 -   Diagram and define the layers of a neural network, introducing the concept of a “convolutional layer”.
 -   Distinguish between a “feature vector” (aka logits) and the last layer (aka softmax probabilities) of a classification network.
 -   Understand the process of “transfer learning”.
+-   Learn about k-nearest neighbors algorithm (_k_-NN).
 -   Learn to save a trained model for re-use later.
