new_loss_class: Loss

Description

new_loss_class() is an alias for Loss(). See ?Loss() for the full documentation.

Usage

new_loss_class(
  classname,
  call = NULL,
  ...,
  public = list(),
  private = list(),
  inherit = NULL,
  parent_env = parent.frame()
)

Value

A function that returns Loss instances, similar to the builtin loss functions.

Arguments

classname

String, the name of the custom class. (Conventionally, CamelCase).

call

function(y_true, y_pred)

Method to be implemented by subclasses: Function that contains the logic for loss calculation using y_true, y_pred.

..., public

Additional methods or public members of the custom class.

private

Named list of R objects (typically, functions) to include in instance private environments. private methods will have all the same symbols in scope as public methods (See section "Symbols in Scope"). Each instance will have it's own private environment. Any objects in private will be invisible from the Keras framework and the Python runtime.

inherit

What the custom class will subclass. By default, the base keras class.

parent_env

The R environment that all class methods will have as a grandparent.
