Common edge-detection filters in convolutional neural networks
Edge-detection filter matrices, also called kernels, detect changes between neighboring image regions. Vertical-edge kernels detect vertical boundaries, while horizontal-edge kernels detect horizontal boundaries. For vertical-edge detection, the Sobel filter gives greater weight to pixels in the central rows, which may make it more robust.

Which of the following do you typically see as you move to deeper layers in a ConvNet?
In order to be able to build very deep networks, we usually only use pooling layers to downsize the height/width of the activation volumes while convolutions are used with “valid” padding. Otherwise, we would downsize the input of the model too quickly.
Training a deeper network (for example, adding additional layers to the network) allows the network to fit more complex functions and thus almost always results in lower training error. For this question, assume we’re referring to “plain” networks.
Suppose you have an input volume of dimension 64x64x16. How many parameters would a single 1x1 convolutional filter have (including the bias)?
