bat-country: an extendible, lightweight Python package for deep dreaming with Caffe and Convolutional Neural Networks

We can’t stop here, this is bat country. Just a few days ago, the Google Research blog published a post demonstrating a unique, interesting, and perhaps even disturbing method to visualize what’s going inside the layers of a Convolutional Neural Network (CNN). Note: Before you go, I suggest taking a look at the images generated using […]
