initializer_identity: Initializer that generates the identity matrix.

In rstudio/keras: R Interface to 'Keras'

Initializer that generates the identity matrix.

Description

Only usable for generating 2D matrices.

Usage

initializer_identity(gain = 1)

Arguments

gain	Multiplicative factor to apply to the identity matrix.

Value

An Initializer instance that can be passed to layer or variable constructors, or called directly with a shape to return a Tensor.

Examples

# Standalone usage:
initializer <- initializer_identity()
values <- initializer(shape = c(2, 2))

# Usage in a Keras layer:
initializer <- initializer_identity()
layer <- layer_dense(units = 3, kernel_initializer = initializer)
