Web10 jan. 2024 · 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. class Linear(keras.layers.Layer): def __init__(self, units=32, … Web8 feb. 2024 · To make custom layer that is trainable, we need to define a class that inherits the Layer base class from Keras. The Python syntax is shown below in the class declaration. This class requires three functions: __init__(), build() and call(). These ensure that our custom layer has a state and computation that can be accessed during training …
