An interview with Kapil Varshney, Data Scientist at Esri R&D

In today’s blog post, I interview Kapil Varshney, a PyImageSearch reader who was recently hired at Esri Research and Development as a Data Scientist focusing on Computer Vision and Deep Learning. Kapil’s story is really important as it shows that, no matter what your background is, you can be successful in computer vision and deep learning — you just […]

Optimizing dlib shape predictor accuracy with find_min_global

In this tutorial you will learn how to use dlib’s find_min_global function to optimize the options and hyperparameters to dlib’s shape predictor, yielding a more accurate model. A few weeks ago I published a two-part series on using dlib to train custom shape predictors: Part one: Training a custom dlib shape predictor Part two: Tuning […]

Label smoothing with Keras, TensorFlow, and Deep Learning

In this tutorial, you will learn two ways to implement label smoothing using Keras, TensorFlow, and Deep Learning. When training your own custom deep neural networks there are two critical questions that you should constantly be asking yourself: Am I overfitting to my training data? Will my model generalize to data outside my training and […]
