Convolutional Neural Network

Today the topic of discussion is Convolutional Neural Network(CNN). We earlier discussed the Feedforward Neural Network where an output of one linear layer was fed to the next layer with an activation layer sandwiched between the two. Here is the link to the article. The CNN is good at identifying the images and classifying them in different classes. Basically a 2D convolution is the sliding of one smaller matrix over the other bigger matrix.
