new_metric_class: Metric

In rstudio/keras: R Interface to 'Keras'

Metric

Description

new_metric_class() is an alias for Metric(). See ⁠?⁠Metric() for the full documentation.

Usage

new_metric_class(
  classname,
  initialize = NULL,
  update_state = NULL,
  result = NULL,
  ...,
  public = list(),
  private = list(),
  inherit = NULL,
  parent_env = parent.frame()
)

Arguments

classname	String, the name of the custom class. (Conventionally, CamelCase).
initialize, update_state, result	Recommended methods to implement. See description section.
..., 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.

Value

A function that returns Metric instances, similar to the builtin metric functions.
