layer_rescaling: Multiply inputs by 'scale' and adds 'offset'

In keras: R Interface to 'Keras'

Multiply inputs by scale and adds offset

Description

Multiply inputs by scale and adds offset

Usage

layer_rescaling(object, scale, offset = 0, ...)

Arguments

object	What to compose the new Layer instance with. Typically a Sequential model or a Tensor (e.g., as returned by layer_input()). The return value depends on object. If object is: missing or NULL, the Layer instance is returned. a Sequential model, the model with an additional layer is returned. a Tensor, the output tensor from layer_instance(object) is returned.
scale	Float, the scale to apply to the inputs.
offset	Float, the offset to apply to the inputs.
...	standard layer arguments.

Details

For instance:

1. To rescale an input in the ⁠[0, 255]⁠ range to be in the ⁠[0, 1]⁠ range, you would pass scale=1./255.

2. To rescale an input in the ⁠[0, 255]⁠ range to be in the ⁠[-1, 1]⁠ range, you would pass ⁠scale = 1/127.5, offset = -1⁠.

The rescaling is applied both during training and inference.

Input shape: Arbitrary.

Output shape: Same as input.
