Print and plot the provided confusion matrix. Normalization can be applied by setting normalize=True.


  • confusion_matrix - confusion matrix to plot
  • classes - class labels
  • normalize - If set to true, normalization will be applied.
  • title - title of the plot
  • color_map - color mapping zmin:
  • output_file - output file to save plot to

density: bool = False,
x_pad_fraction: float = 0.05,

Plots a side-by-side comparative histogram of the confidence distribution.


  • histogram_data - Two data vectors
  • title - Title to be displayed above the plot
  • output_file - File to save the plot to
  • num_bins - Number of bins to be used for the histogram
  • colors - Left and right bar colors as hex color strings
  • axes_label - Labels shown above the left and right histogram, respectively
  • frame_label - Labels shown below and on the left of the histogram, respectively
  • density - If true, generate a probability density histogram
  • x_pad_fraction - Percentage of extra space in the horizontal direction
  • y_pad_fraction - Percentage of extra space in the vertical direction


def plot_curve(output_directory: Text, number_of_examples: List[int],
x_label_text: Text, y_label_text: Text,
graph_path: Text) -> None

Plot the results from a model comparison.


  • output_directory - Output directory to save resulting plots to
  • number_of_examples - Number of examples per run
  • x_label_text - text for the x axis
  • y_label_text - text for the y axis
  • graph_path - output path of the plot
