WebJan 10, 2024 · The Layer class: the combination of state (weights) and some computation. One of the central abstraction in Keras is the Layer class. A layer encapsulates both a state (the layer's "weights") and a transformation from inputs to outputs (a "call", the layer's forward pass). Here's a densely-connected layer. It has a state: the variables w and b. WebForward propagation (or forward pass) refers to the calculation and storage of intermediate variables (including outputs) for a neural network in order from the input layer to the …
