@yosinski could you help with it when you have time? Many thanks.

The maximal activations has two flavors:

1. Using an existing dataset of images - the tool goes over all the images and checks which [9] images are maximizing the activation value of a neuron, it does it for every neuron
2. Using optimization - the tool generates an image which maximizes the activation value of a neuron, it does it by running a gradient ascent process
