plot.keras_training_history: Plot training history

In keras3: R Interface to 'Keras'

Plot training history

Description

Plots metrics recorded during training.

Usage

## S3 method for class 'keras_training_history'
plot(
  x,
  y,
  metrics = NULL,
  method = c("auto", "ggplot2", "base"),
  smooth = getOption("keras.plot.history.smooth", TRUE),
  theme_bw = getOption("keras.plot.history.theme_bw", FALSE),
  ...
)

Arguments

x	Training history object returned from fit.keras.src.models.model.Model().
y	Unused.
metrics	One or more metrics to plot (e.g. c('loss', 'accuracy')). Defaults to plotting all captured metrics.
method	Method to use for plotting. The default "auto" will use ggplot2 if available, and otherwise will use base graphics.
smooth	Whether a loess smooth should be added to the plot, only available for the ggplot2 method. If the number of epochs is smaller than ten, it is forced to false.
theme_bw	Use ggplot2::theme_bw() to plot the history in black and white.
...	Additional parameters to pass to the plot() method.

Value

if method == "ggplot2", the ggplot object is returned. If method == "base", then this function will draw to the graphics device and return NULL, invisibly.
