Question 1

CNN (Convolutional Neural Network)

Answer 1

Type of ANN, does pattern recognition on images

Question 2

Components of CNN

Answer 2

Convolution operation – filter slides over image extracting local features, Layers – convolutional (for feature extraction), pooling (for dimensionality reduction), and fully connected (for classification)

Question 3

Why CNN

Answer 3

Neuron doesn’t need to see whole image to find pattern, often patterns smaller than whole image, same pattern can appear in different regions, subsampling pixels (making image smaller) will not impact model.
