Call()
call() is the Keras method that defines the forward computation a layer or model performs on its inputs.
Deep Learning with R, Third Edition
A call method defines the forward computation performed when a neural-network layer or model receives inputs.
- How it is used
- Defines the forward data transformation executed when a Keras layer or model receives inputs.
- How deep it goes
- Explains implementation through custom dense and diffusion examples, while deferring detailed build() behavior.
- Examples
- Uses SimpleDense, shape inference, diffusion denoising, and PyTorch linear models to demonstrate forward computation.
- What you can do after
- Build custom Keras layers that transform inputs and return outputs through a call() method.

Deep Learning with Python, Third Edition
A Keras layer or model method that defines the forward computation applied to inputs.
- How it is used
- Defines the forward computation inside custom Keras layers and models.
- How deep it goes
- Explains implementation with matrix multiplication and activation, while deferring broader build mechanics to adjacent treatment.
- Examples
- Uses a SimpleDense layer that multiplies inputs by W, adds b, applies ReLU, and maps 784 features to 32 outputs.
- What you can do after
- Build it from scratch by implementing call() for a custom Keras layer’s forward computation.
