A day in the life of a Adrian Rosebrock: computer vision researcher, developer, and entrepreneur.


Ever wonder what it’s like to work as a computer vision researcher or developer?

You’re not alone.

Over the past few years running PyImageSearch I have received emails and inquiries that are “outside” traditional computer vision and OpenCV questions.

They instead focus on something much more personal — my daily life.

PyImageSearch reader Jared, asked:

“What is it like being a computer vision researcher and developer? What do you actually do day-to-day?”

Another reader, Miguel, inquired:

“You’ve written a computer vision book and a course. And now you’re starting a new book on deep learning? How do you get all this done? What’s your secret?”

Saanvi’s suggestion is one of my personal favorites:

“Adrian, you should write your next book on productivity.”

Now that the Deep Learning for Computer vision with Python Kickstarter campaign is online, I’ve been getting more of these questions than ever.

Because of this, I thought I could do something a little different today — give you an exclusive, behind the scenes look at:

  • How I spend my day.
  • What it’s like balancing my role as a computer vision researcher/developer with a writer on PyImageSearch.
  • The habits and practices I’ve spent years perfecting to help me get shit done.

To see what it’s like to live a day in my shoes, keep reading.

Morning (5:15AM – 12:00PM)

The follow blog post follows my daily activities on Monday, January 23rd.

Getting out of bed

Figure 1: I wake up around 5:15AM every morning.

Figure 1: I wake up around 5:15AM-5:20 every morning.


My alarm goes off on my iPhone.

I reach over and turn it off after a few seconds, readjusting to consciousness.

Time to get out of bed.

I don’t think twice about it.

I don’t check Facebook notifications. I don’t look a Twitter. And I don’t even think about checking email.

I sit up


And immediately drink 12oz of water from the Nalgene on my nightstand.

The water helps start my metabolism, flushes out toxins built up from the night before, and most importantly, helps me hydrate — at this point I’ve gone ~8 hours without water and I need to rehydrate. Your brain tissue is 75% water after all.

This 12oz of water is the first of ~200oz I’ll consume throughout the rest of the day.

The day has started and I only have one goal: get shit done.

Caffeinate (strategically)

Figure 2: Every day starts off with a strong cup of coffee with a splash of heavy cream. This is my only caffeine intake for the entire day.

Figure 2: Every day starts off with a strong cup of coffee with a splash of heavy cream. This is my only caffeine intake for the entire day.

My work day starts immediately.

I walk from the bedroom to the kitchen and prepare a nice hot cup of coffee — this is the only caffeine I will consume the entire day.

Don’t get me wrong:

I love coffee.

But I’m also a strong believer in the strategic use of caffeine (whether in coffee or tea form).

Back in graduate school I would drink a large mug of coffee in the morning followed by a massive iced coffee from Dunkin Donuts soon after lunch. By the afternoon I felt exhausted. I didn’t realize my caffeine intake was actually hurting my productivity.

Caffeine may give you a short term jolt of energy, but it also comes with a crash later on in the day. Therefore, we can actually view consuming caffeine as borrowing energy from later in the day. That energy and focus have to come from somewhere. And unfortunately, that “loan” must be paid in the afternoon during our crash.

Two years ago I stopped consuming large amounts of caffeine.

Now all I have is a (very) strong dark roast in the morning with a splash of heavy cream. The heavy cream contains fats that help jumpstart by brain. I avoid sugar as much as possible.

Check on neural network training

I’m currently running a Kickstarter campaign to fund the creation of my new book, Deep Learning for Computer Vision with Python.

For this book I am running a bunch of experiments where I train various network architectures (AlexNet, VGGNet, SqueezeNet, GoogLeNet, ResNet, etc.) on the massive ImageNet dataset.

I currently have experiments running for both VGGNet and SqueezeNet. These networks have been training overnight so I need to:

  • Inspect their accuracy/loss curves.
  • Determine if the networks are overfitting (or at risk for overfitting).
  • Adjust any relevant hyperparameters (i.e., learning rate, weight decay) and restart training.
  • Estimate when I should check the networks again.

First up is VGGNet:

Figure 3: VGGNet is hitting 53.52% rank-1 accuracy after 20 epochs. Learning is starting to stagnate, but adjusting the learning rate now would be too early.

Figure 3: VGGNet is hitting 53.52% rank-1 accuracy after 20 epochs. Learning is starting to stagnate, but adjusting the learning rate now would be too early.

After just 20 epochs of training VGGNet is hitting 53.52% rank-1 accuracy.

Accuracy (and loss, not pictured) are starting to stagnate slightly — I will likely have to lower the learning rate from 1e-2 to 1e-3 within the next 20 epochs.

Then comes SqueezeNet:

Figure 4: Learning has definitely stagnated for SqueezeNet. Time to update the learning rate.

Figure 4: Learning has definitely stagnated for SqueezeNet. Time to update the learning rate.

Epochs 0-45 were trained with a 1e-2 learning rate. As training and validation accuracy/loss started to diverge around epoch 45 I updated the learning rate to be 1e-3.

However, we can now see that learning is quite stagnated and unable to get above the 50.2% rank-1 hump.

We are also getting a bit of overfitting, but nothing too terribly concerning (yet).

I’m going to change the learning rate to 1e-4, but I’m not really expecting any more large gains in accuracy out of the experiment at this point.

Future experiments with include replacing the default activation function (ReLU) with a leaky ReLU variant (such as ELU). I’m also considering playing around with adding BatchNorm layers to the architecture as I’m unaware of any previous SqueezeNet experiments that have done this, but I have seen it (successfully) work before with other micro-architectures such as GoogLeNet and ResNet (experimenting is half the fun, after all).

The reason why I spend the first 10 minutes of my morning look at training progress is so I can update any relevant hyperparameters and continue training the network.

Some of these networks can take a long time to train (VGGNet is currently taking ~2.9 hours per epoch) so it’s important to spend time looking at the accuracy/loss, then moving on with your day (and trying not to think about them again until you have more data to make an informed decision with).

When I first started working with deep learning I was guilty of making a critical mistake: looking at my loss/accuracy plots too often.

When training deep neural networks you often need the context of 10-15 epochs to make informed decisions regarding updating learning rates and which epoch you restart training at. Without this context you’ll find yourself spinning your wheels and overthinking the training process.

Let your network train.

The results will come in.

And then you’ll be able to make an informed decision on how to continue.

What about email?

You might be wondering why I’m not popping open my inbox and reading through my email?

The answer is because my mornings are my most productive and creative time of the day, thus I guard this time very closely. These hours of the day are the equivalent to by Biological Prime Time where I have the most energy and are most likely to be hyper productive.

In short, my goal for this time of day is to reach flow state as soon as possible and maintain it for as long as possible.

I classify email as a procedural task — read email, reply, and repeat until inbox is empty. It’s not task that requires creative energy.

On the other hand, there are a lot of tasks I undertake that are creative in nature. Examples include:

  • Writing a new blog post/tutorial.
  • Outlining a chapter in my upcoming deep learning book.
  • Working on a tricky piece of code.
  • Researching a new algorithm.

All of these tasks require a bit of extra brainpower stemming from the creative side. I spend my mornings working on these types of tasks. Email has its place, just not until later in the day.

Planning my “3 Big Things”

I first heard the phrase “relentless execution” from Rob Walling a year or two ago at a conference. The cornerstone of the idea is something we’re all familiar with:

  1. Break a complex project down into smaller pieces/sub-pieces.
  2. Individually complete each piece.
  3. Combine the pieces together to form the solution to the problem.

The concept of relentless execution focuses on Step #2. Once we’ve identified the parts that make up the whole, we need to relentlessly and consistently complete them on a day-to-day basis.

This also goes hand-in-hand with incremental improvement — small, consistent daily changes added up over a period of time yield large growth.

To facilitate this process I spend every Sunday morning planning out the tasks that I want to get done the following week. You can think of this list as an informal sprint task list that developers use, except:

  1. This list combines business and software tasks.
  2. Is done on a weekly basis rather than every 2-3 weeks.

Every morning I take three of the tasks from my weekly list and add them to my 3 Big Things I aim to accomplish for the day:

Figure 5: Setting my "3 big things" for the day. My goal will be to accomplish all three of these tasks before my day ends.

Figure 5: Setting my “3 Big Things” for the day. My goal will be to accomplish all three of these tasks before my day ends. (Note: Apparently I missed the “3” in “23” when writing in my notebook that day — I’m only human after all!)

Today my three big tasks are:

  1. Document “A day in my life” (which allowed me to write this blog post).
  2. Plan out the Kickstarter stretch goals for my deep learning book (which you can find here).
  3. Start working with age/gender classification (one chapter in my upcoming deep learning book will demonstrate how to use CNNs to classify the age and gender of a person from a photo; more on that later in this post).

Again, Being productive and solving challenging problems isn’t about solving them all at once. Instead, break down large, complex problems into smaller pieces and solve each of them individually. Doing this on a daily basis guarantees you incremental “wins” which add up in the long run. Not to mention, aiming for smaller wins in the short term allows you to create momentum and gives your brain a nice endorphin rush.

If you haven’t noticed yet, I’m a big productivity geek so if you’re interested in learning more about productivity hacks you can apply to your own life, check out The Productivity Project: Accomplishing More by Managing your Time, Attention, and Energy by Chris Bailey.

I normally don’t recommend productivity books (since they tend to rehash the same material), but Chris’ is the real deal.

Start on item #1

After I’ve mapped out my “3 Big Things” for the day I immediately jump into the first one.

Today is a special case since I’m already documenting my day and will be for the rest of the day.

I then move into #2, planning out the Kickstarter stretch goals. I’ll continue doing this task until breakfast.


My mother always told me that breakfast is the most important meal of the day — I never believed her, but then again, that might be because I didn’t get out of bed until 10:30AM when I was in college.

It wasn’t until I started getting up around 5AM in the morning every day that my perspective shifted and I realized breakfast is the most important meal (at least for me).

Having a large healthy breakfast of proteins, fats, and veggies ensures that I’ll be able to come off the caffeine high and continue to be productive, even towards the end of the morning. Furthermore, going with a high protein, high fat diet ensures the fats deliver a longer, sustainable energy burn throughout the rest of the day — this is also beneficial when I go to the gym in the mid-afternoon.

For the health geeks out there (like me) I’m referring to a paleo-esque diet, a diet that consists predominantly of veggies, fruits, nuts, roots, and meats. Dairy products (there is no lactose in heavy cream), grains, and processed foods are avoided.

There are many variations and interpretations of the paleo diet and it’s taken me a few years to zero-in on what works for me. For example, I’ve been able to add in small amounts of dairy (like cheese) into my diet without adverse affects. The fun part about these types of diets is finding what works for you personally.

In my case, I’m fortunate enough to have a fiancé that prepares breakfast every morning (yes, every morning). I’m extremely lucky and grateful to have hit such a jackpot.

At around 7:45AM her and I eat breakfast together before she heads off to work. Doing this ensures we have quality time together every morning:

Figure 7: Between 7-7:30AM each morning I have a breakfast heavy in proteins and fats.

Figure 7: Between 7-7:30AM each morning I have a breakfast heavy in proteins and fats.

Today I’m having:

  • Three eggs scrambled with sausage, onions, peppers, and spinach.
  • Two slices of bacon.
  • A handful of orange slices.

Her and I have breakfast together and then around 8:15AM I go back to work.

Turning off notifications

After breakfast all notifications go off so I can reach and maintain flow state.

My iPhone is silenced.

Slack is shut down.

I don’t even think about checking Facebook, Twitter, or reddit.

Next I put on Gunnar eye glasses (to reduce eye strain; I have issues with ocular migraines if I strain my eyes too long under stressful situations) and noise canceling headphones to ensure I’m not disturbed:

Figure 8: Noise canceling headphones and strain reducing glasses help me reach (and sustain) flow state.

Figure 8: Noise canceling headphones and strain reducing glasses help me reach (and sustain) flow state.

Lastly, I even turn off the actual clock on my desktop:

Figure 9: No distractions include turning off the clock on my desktop.

Figure 9: No distractions include turning off the clock on my desktop.

Time is constant distraction. It’s too easy to look up from your work and think “Man, I’ve been at this for 40 minutes” and then allow your mind to wonder. In short, looking at the clock breaks flow state.

Instead, turn off your clock and stop caring — you’ll realize that time is relative and you’ll break from flow when you’re naturally tired.

Now that I’m “in the zone” my goal is to finish up planning the Kickstarter stretch goals along with creating visualizations for GoogLeNet’s Inception module and ResNet’s Residual module:

Figure 10: Tackling the first task on my list for the day -- planning the stretch goals and designing images for them.

Figure 10: Tackling the first task on my list for the day — planning the stretch goals and designing images for them.

By 10:54AM I have finished planning the Kickstarter stretch goals and the network module visualizations.

From there I come out of flow so I can share the latest PyImageSearch blog post on social media (since it’s a Monday and new posts are published on Mondays):

Figure 11: Since it's a Monday I need to compose a tweet for the latest blog post that was just published on PyImageSearch.com.

Figure 11: Since it’s a Monday I need to compose a tweet for the latest blog post that was just published on PyImageSearch.com.

Before lunch I check-in on SqueezeNet again and see that loss and accuracy have topped out. I’m also seeing the threat of overfitting becoming bothersome (but again, not terrible):

Figure 12: Maxing out SqueezeNet accuracy for my current experiment. Time to record the results in my lab journal and try something new.

Figure 12: Maxing out SqueezeNet accuracy for my current experiment. Time to record the results in my lab journal and try something new.

I log the results to my lab journal and then update the code to experiment with BatchNorm. I kick the experiment off — and then it’s time for lunch.


My ideal time to eat lunch is between 11:00-11:30AM.

I normally eat leftovers from dinner the night before or a salad from the shop down the street. Since I don’t have any leftovers from last night, I opted for a salad:

Figure 13: A lighter lunch, but still packed with good fats.

Figure 13: A lighter lunch, but still packed with good fats.

On my salad I have roasted turkey, tomato, avocado (healthy fats!) and yes, a tiny bit of cheese. As I mentioned above, I’ve tweaked my own personal paleo diet over the years and found I can consume small amounts of dairy without it affecting my energy levels or overall health.

At this point I start consuming my daily allotment of coconut water (about 300mL) along with my regular water. Coconut water helps reduce cortisol levels which in turn reduces stress. It’s also a good source of potassium.

Meditation and mindfulness

After lunch I spend 10-15 minutes meditating. I personally like to use the Calm app:

Figure 14: I like to use the Calm app for mindfulness and meditation.

Figure 14: I like to use the Calm app for mindfulness and meditation.

A bit of mindfulness allows me to re-center myself and continue with my day.

Afternoon (12:00PM – 5PM)

I start off my afternoon by picking the next uncompleted task off my “3 Big Things” list and cranking away on it. I continue to keep notifications off and keep my noise canceling headphones on.

If I’m outline a tutorial or writing a blog post I tend to go for instrumental music. This Will Destroy YouExplosions in the Sky, and God is an Astronaut are personal favorites for these types of task. The lack of lyrics allows me to not get distracted (I tend to sing along if there are lyrics).

On the other hand, if I’m writing code I normally default to music with lyrics — genres such as ska, punk, and hardcore are my favorite. I’ve spent countless hours in my lifetime coding to bands such as Minor ThreatDillinger Four, and The Mighty Mighty Bosstones.

Today I’m starting some experiments for the age and gender classification chapter of my upcoming deep learning book. Given a photo of a person the goal is to:

  1. Detect the face in the image.
  2. Determine the age of the person.
  3. Approximate the gender of the person.

Deep learning algorithms have been quite successful for this specific task and will make for an excellent chapter in the book.

To start, I download the IMDB-WIKI face image dataset and start exploring.

My first task is to understand the .mat  annotation file included with the dataset. After ~45 minutes of hacking I’m able to extract the date of birth, age, and bounding box for each face in the dataset:

Figure 15: Exploring the IMBDB-WIKI dataset and unpacking the annotations file.

Figure 15: Exploring the IMBDB-WIKI dataset and unpacking the annotations file.

I then take a subset of the data and attempt to fine-tune VGG16 on the data as an initial trial run:

Figure 16: A simple "proof of concept" experiment demonstrating that VGG16 can be fine-tuned for gender classification. This simple approach is obtaining 91%+ accuracy after only 5 epochs.

Figure 16: A simple “proof of concept” experiment demonstrating that VGG16 can be fine-tuned for gender classification. This simple approach is obtaining 91%+ accuracy after only 5 epochs.

As the above screenshot demonstrates, after only a 5 epochs I’m getting 91%+ gender classification accuracy. This initial experiment is successful and warrants more exploration into fine-tuning VGG16.

Around 2:30-3PM I head to the gym for 1-1.5 hours.

Fitness is a huge part of my life.

I’ve played sports since I was a kid — soccer, baseball, basketball, you name it.

During my first year of graduate school I started weight lifting. I spent about a year lifting with a friend, and then when he graduated, I spent another year working out solo.

From there I found I got bored of the regular gym routine and started doing CrossFit. That eventually led me to olympic lifting. I now do a hybrid of olympic lifting (for strength) and CrossFit (for stamina).

The important takeaway here is the physical exercise is key to a healthy life. It doesn’t have to be much — just getting out of your chair (or better yet, use a standing desk) and going for a walk around the block can dramatically increase your productivity (and save you from heart issues). Find out what works for you and keep doing it. But also be mindful of what worked for you five years ago may not be working for you now.

Once I get back to the gym I shower and log back in to my computer.

Evening (5PM – 8PM)

At this point in the day the creative portion of my brain is exhausted. I’ve been up for approximately 12 hours and I’m hitting the natural cycle of my day where I have less energy.

That said, I can still handle procedural tasks without a problem, thus I spend much of this time reading and replying to emails.

If I don’t have any emails to answer, I might work on a bit of code.

Night (8PM – 10:30PM)

Once 8PM rolls around I try to disconnect as much as possible.

My laptop goes into sleep mood and I try to stay off my phone.

I normally like to unwind at the end of the night playing whatever my favorite RPG is at the moment:

Figure 17: Spending the night unwinding and playing a bit of old school Final Fantasy on the SNES.

Figure 17: Spending the night unwinding and playing a bit of old school Final Fantasy on the SNES.

I just beat The Witcher III: Wild Hunt (a game that has made its way into my  “all time favorites list”) so I’m currently I’m playing through Final Fantasy VI (called Final Fantasy III in North America) on the SNES.

After a bit of gaming I might watch a bit of TV before calling it a night.

Then, it’s off to bed — ready to “relentlessly execute” the following morning.

    Ironically, I read this post when I should have been getting out of bed instead. Also, I assume you got dressed at some point, right? ? Lastly, some obnoxious grammar pedantry: “She and I have breakfast”.

    • Adrian Rosebrock January 30, 2017 at 4:16 pm #

      Well, some mornings 😉 When your “office” is just down the hallway it becomes hard to change out of sweats if you don’t have any calls or meetings during the day.

  8. Brian January 30, 2017 at 11:53 am #

    Absolutely brilliant! Having a ultra-productive day is extremely rewarding, but to document it in such detail must have been an excruciating yet fun lay-over task. Have you ever tried counting the number of intersections you drive through when going from point A to B? It’s a great exercise in “brain focus”, and nearly impossible for longer drives through the city. But I digress… I love the phrase: “Relentless execution”. Massive success on your new book!

    • Adrian Rosebrock January 30, 2017 at 4:15 pm #

      Hey Brian, thanks for the comment. The phrase “relentless execution actually comes from Rob Walling — I can’t take credit for it 😉

      I’ve never tried counting the number of intersections I drive through. It sounds a lot like walking meditation only for driving. Next time I’m the car I’ll give it a try 🙂

  9. Tyler January 30, 2017 at 12:52 pm #

    Nice read!

    I’ve noticed that I am distracted a lot by having ambient light. Darkness sort of helps me focus, and is less stressful of an environment for me.

    Being more of a night person myself, are you more of a day person by nature, or do you simply find that you are more productive during the day?

    Good points on nutrition. Looking forward to the deep learning book!

    • Adrian Rosebrock January 30, 2017 at 4:14 pm #

      During my teenage and early college years I was absolutely a night person. I hated being awake early in the morning. However, that started to change my junior year when I logged my productivity. I noticed that I had more creative energy in the morning. Now it’s evolved to the point where I get up early and have my most creative time undisrupted.

  10. steve southworth January 30, 2017 at 1:14 pm #

    Thnks, you do good work.

    Maybe (in your spare time) you could jot down some notes on “best practices”

    • Adrian Rosebrock January 30, 2017 at 4:13 pm #

      What specific type of best practices are you interested in?

  11. Karolis January 30, 2017 at 1:31 pm #

    I am a sucker for reading about other people’s routines and this one is wildly impressive! Shows how important it is to forge your own path so as to be able to create the routine that helps you roll at your 100%. If you work at an office and have to be there at 8 am, and then have a meeting at 9 am, and then water-cooler chit-chat and so on, it’s pretty much impossible to get anything meaningful done.

    One question I am curious about, have you always been an early bird or how did get into the rhythm of getting up so early?

    • Adrian Rosebrock January 30, 2017 at 4:12 pm #

      I totally agree Karolis — being able to have control over your schedule can make a huge impact on your productivity. Once I learned the concept of a “Biological Primetime” I started to track it over a month period. From there I started to schedule my hardest classes during these times, my study periods, and any work that as critical that needed to be accomplished during the day. I was also very defensive around these times and wouldn’t let anything schedule with them.

      To answer your question, no, I was not always a morning person. As a young kid (birth to ~8 years old) I got up around 5AM every morning. As I grew into my teenage years I slept consistently to 10:30-11AM every morning. This continued until junior year of college when I started slowly getting up earlier. Each month I bumped it back 30 minutes until I found myself naturally getting up around 5:30AM and feeling great.

  12. Preetinder Singh January 30, 2017 at 2:27 pm #

    Quite empowering 🙂

    Very interesting read. Thanks also for sharing. I have identified several things you do that will improve my productivity. I am already trying to eat right and exercise, but the other things you did to be productive were very enlightening. Thanks. I have just recently started reading your posts and am going back and reading others. I am excited about the deep learning book and wish you well in it’s development. I can hardly wait, but I will. Looking forward to many future posts and your books.

    • Adrian Rosebrock February 1, 2017 at 1:00 pm #

      Thanks David, I’m happy the blog post helped! I hope I can do more of these types of “behind the scenes” posts in the future.

  15. Hilman January 30, 2017 at 11:09 pm #

    Quite same with me! Waking up early, taking care of food intake, and do something else at night. Except that I will always have a 5 times break interval because as a Muslim, I need to do the prayers. By the way Adrian, I am also a productive geek ?. We are on the same ship here…

    • Adrian Rosebrock February 1, 2017 at 12:59 pm #

      Taking breaks is extremely important. It’s great that your religion facilitates this. In Western culture it becomes too easy to spend all your time working and burn yourself out.

      • Hilman February 1, 2017 at 5:53 pm #

        A little correction. 4 times break per day.
        The first prayer is at the early morning, and it does facilitates me to wake up early.

        Whatever it is, keep spreading your knowledge Adrian! It can really change the world.

    This is fantastic one of a kind mannerism.

    I always wondered how you managed all this writing(my question answered).

    Thanks for sharing the details of your day with some interesting pointers. I wonder how do you manage the deviations – snags, interruptions, or travel.

    • Adrian Rosebrock February 1, 2017 at 12:43 pm #

      When it comes to travel I always plan ahead — this includes my Sunday’s when I sit down and plan my week. I make sure to account for the fact that I’ll be traveling and purposely put less on my to-do list. If I go on long vacations I normally block out time to get work done one morning.

      As for snags and interruptions, they happen all the time to everyone. At that point it’s more of a mindset problem — accepting there are things outside of your control and not getting upset by it.

    I admire your speed of text processing. Your blog is fascinating to read. My reading can’t even keep up with your writing.

    I spent lots of time reading and ended up with very little time writing each day. If I write, my writing is very slow, and I can call that a writing day. I imagine you got a lot to read and you are already writing a lot! Could you also share a little bit about how you do writing efficiently?

    • Adrian Rosebrock February 3, 2017 at 11:24 am #

      Hi Jay — for me writing is a habit just like anything else. I make it a habit to write 1,000 words per day. If I am in the process of writing a book I will often go on “writing binges” where I write 5,000-10,000 words per day for 3 days straight, then spend 2 days recovering and doing as little writing as possible. This is made possible having really good outlines. I’ll consider doing a tutorial on writing efficiently and effectively, although I don’t think the PyImageSearch.com blog is the write outlet for such a post.

    Great post, Adrian. I look forward to more behind the scenes looks at PyImageSearch. Also, I now know your productivity secret: you skip dinner! Jk, I’m sure you have it sometime in the evening!

    • Adrian Rosebrock February 3, 2017 at 11:20 am #

      My dinner time normally fluctuates a bit since it’s dependent on my fiance’s schedule and when she gets home from work 🙂

  22. Kapil February 1, 2017 at 10:50 pm #

    Hey Adrian,
    Your post made be feel ashamed of my disorganized life. Well it’s time for me to introspect and organize life to increase productivity. Thanks for sharing mate. As always you rock.

    • Adrian Rosebrock February 3, 2017 at 11:19 am #

      Thanks Kapil! 🙂

  23. Simon Burfield February 2, 2017 at 5:35 am #

    Good post mate :0

      Thanks Simon!

    I have issues with ocular migraines too. I need to buy that glasses. Thank you. By the way that was a good blog post 😉

    • Adrian Rosebrock February 3, 2017 at 11:18 am #

      They really work, I highly recommend them! Also consistent usage of coconut water and mindfulness have helped reduce stress which in turn have reduced my ocular migraines.

  25. Roger February 2, 2017 at 7:35 am #

    Thanks for sharing your routine.

    Two questions:
    1) which exact model is your gunnar eyeglasses? Does they really produce less eye fatigue?
    2) with your high productive, intensive and “day-consuming” routine how do you manage the time to pass with your girlfriend? Doesn’t she complain that you spend little time with you?

    • Adrian Rosebrock February 3, 2017 at 11:17 am #

      1. I have two pairs. Here is one pair. I can’t seem to find the second model on the Gunnar site though. It may have been discontinued. And yes, they do help with eye fatique.

      2. Actually, if you look at my daily schedule her and I have plenty of time to spend with each other — more than most couples do. We always eat breakfast together and spend time together in the morning (30-60 minutes). We also have evenings together as well (anytime past 6:30-7PM). She also works so her day is busy as well.

      • Roger February 10, 2017 at 9:14 am #

        Thanks for you reply.

        Some other questions:
        1) What webapp do you use for drawing flow-chart diagrams?
        2) Does you girlfriend complain that in the evenings you play Final Fantasy or other retro-gaming consoles? How do you manage evening times and retro-gaming (or other interests you may have)? For me it’s very hard because my wife always pretends that after work time I spend nearly all time with her and my interests time tends to zero. Do I have to eliminate my interests or to change wife? 🙂

        Thanks for answering these private questions too.

        • Adrian Rosebrock February 10, 2017 at 1:57 pm #

          Hey Roger, thanks for the comment. To answer your questions:

          1. I use LucidChart for diagrams.
          2. My fiance actually works later than I do some nights, so I often have an hour or so to myself to hang out and play video games. During the weekend we spend a lot of focused time together. In your particular situation, I would suggest having an honest conversation with your life and letting her know that you need your personal time to either (1) code or (2) play video games. I personally need at least 1-3 hours per day of “alone time” or I start to lose my mind 😉

    Thank you for sharing this, Adrian. You are a tremendous inspiration!! Congratulations on everything.

      Thanks Greg!

    This is a very useful post.
    I have a or actually two question as follows: –
    1. Why you don’t eat dairy food?
    2. Headphone all the time will have negative effects on ears and
    3. Magnet all the time on head is not good.

    What do you think about it?

    • Adrian Rosebrock February 7, 2017 at 9:20 am #

      1. Humans are one of the few (only?) mammals that can actually consume dairy passed nursing years. Some people have problems processing dairy. This is called lactose intolerance. Through my diet I’ve found that I can consume small amounts of dairy, but too much dairy can cause stomach problems.
      2-3. I don’t wear headphones all the time, only when I want to focus and not be distracted.

      • Shamail February 7, 2017 at 10:05 am #

        Thanks a lot, so nice of you to reply to the question in comments.

  28. Martyna February 6, 2017 at 2:46 am #

    Hey Adrian,
    Which part of the day you check your phone on purpose?
    Also, tell us what you eat for dinner 🙂

    • Adrian Rosebrock February 7, 2017 at 9:15 am #

      I will normally check my phone on purpose before or after lunch, before I go to the gym, and after I shower in the afternoon. As for dinner, it’s basically whatever follows my paleo-esque diet.

  29. Alex February 11, 2017 at 4:16 am #

    Excellent and very interesting article! I’d love to be able to work from home a bit more than I do – though it might be a bit distracting with children!

    I see you check on your experiments in the morning and look at fine tuning the learning rates. What do you find the best way to do this? Do you have to checkpoint, kill the algorithm, adjust the learning rates and then restart training?



    • Adrian Rosebrock February 13, 2017 at 1:51 pm #

      You’re exactly right Alex. I normally checkpoints the weights + optimizer state to disk every epoch. Then I kill the process, update my learning rate, and restart training. I’ll be covering the exact process more in my upcoming book.

  30. Casey Clayton February 13, 2017 at 1:26 pm #

    Excellent post. I will definitely have to try out this process for my personal projects on the weekends.

    • Adrian Rosebrock February 13, 2017 at 1:28 pm #

      Thanks Casey, I’m glad you enjoyed it!
