What are Kernels, Convolutions, Feature Maps, Filters, Convolutions, Channels in CNNs?

More questions:

  1. What is the difference between a kernel and a convolution?
  2. What is the difference between a feed forward network and a convolutional network?
  3. Why are the number of filters and channel ouputs the same?
  4. We progressively decrease the image size (term “image map” or “feature map”) while we increase the number of channels ( why ??? )
