plot_param_importances

Visualize the importance of hyperparameters in optimization studies. Specify parameters, target values, and names to generate a clear plot for analyzing parameter impact on results.

Instructions

Return the parameter importances plot as an image.

    Args:
        params:
            Parameter list to visualize. The default is all parameters.
        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.
            By default, all objective will be plotted by setting target to None.
        target_name:
            Target’s name to display on the legend.
