initializer_constant: Initializer that generates tensors with constant values.

In rstudio/keras: R Interface to 'Keras'

Initializer that generates tensors with constant values.

Description

Only scalar values are allowed. The constant value provided must be convertible to the dtype requested when calling the initializer.

Usage

initializer_constant(value = 0)

Arguments

value

A numeric scalar.

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_constant(10)
values <- initializer(shape = c(2, 2))

# Usage in a Keras layer:
initializer <- initializer_constant(10)
layer <- layer_dense(units = 3, kernel_initializer = initializer)
