plot_slice

Generate slice plots for hyperparameter optimization results. Visualize parameter impact on target values, specify axes labels, and analyze optimization trends effectively.

Instructions

Return the slice 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.
        target_name:
            Target’s name to display on the axis label.
