What are they: Convolutional Neural Networks are a type of Neural Networks that use the operation of convolution (sliding a filter across an image) in order to extract relevant features. Why do we need them: They perform better on data (rather than using normal dense Neural Networks) in which there is a strong correlation between, for example, pixels because the spatial context is not lost Convolutional Neural Networks To address this problem, bionic convolutional neural networks are proposed to reduced the number of parameters and adapt the network architecture specifically to vision tasks.
