Then, we'll see how to do it using PyTorch's nn module which provides a much more convenient and powerful method for defining network architectures. Our input image is a Variable but is not a leaf of the tree that requires computation of gradients. It uses a filter based on the derivative of a Gaussian in order to compute the intensity of the gradients. PyTorch also allows you to convert a model to a mobile version, but you will need Caffe2 – they provide quite useful documentation for this. The diagonal elements represent the number of points for which the predicted label is equal to the true label, while off-diagonal elements are those that are mislabeled by the classifier.
