plot_optimization_history
Visualize optimization history as an image to analyze hyperparameter tuning progress. Specify target index for multi-objective optimization or use auto-detection for single-objective tasks.
Instructions
Return the optimization history plot as an image.
Args:
target:
An index to specify the value to display. To plot nth objective value, set this to n.
Note that this is 0-indexed, i.e., to plot the first objective value, set this to 0.
For single-objective optimization, None (auto) is recommended.
For multi-objective optimization, this must be specified.
target_name:
Target's name to display on the axis label and the legend.
