Web2. Define and intialize the neural network¶. Our network will recognize images. We will use a process built into PyTorch called convolution. Convolution adds each element of an image to its local neighbors, weighted by a kernel, or a small matrix, that helps us extract certain features (like edge detection, sharpness, blurriness, etc.) from the input image.
