Convolutional Neural Network

Inspiration Convolutional Neural Networks are a kind of network inspired by the cats’ visual cortex. A cat visual cortex is made of 2 distinct type of cells: simple cells which specializes into edge detection. complex cells with larger receptive field which are sensitive to a small region of the visual field and are less sensitive to the exact […]

Keras – Tensorflow and Theano abstraction

As we’ve seen in the Tensorflow introduction having access to the computation  is a powerful feature. We can define any operation we’d like and tensor flow (or Theano) will compute the gradient and perform the optimisation for us. That’s great! However if you always define the same kind of operation you’ll eventually find this approach a […]
