abstract = {Objective
Evaluating the performance of multiple complex models, such as those found in biology, medicine, climatology, and machine learning, using conventional approaches is often challenging when using various evaluation metrics simultaneously. The traditional approach, which relies on presenting multi-model evaluation scores in the table, presents an obstacle when determining the similarities between the models and the order of performance.
Methods
By combining statistics, information theory, and data visualization, juxtaposed Taylor and Mutual Information Diagrams permit users to track and summarize the performance of one model or a collection of different models. To uncover linear and nonlinear relationships between models, users may visualize one or both charts.
Results
Our library presents the first publicly available implementation of the Mutual Information Diagram and its new interactive capabilities, as well as the first publicly available implementation of an interactive Taylor Diagram. Extensions have been implemented so that both diagrams can display temporality, multimodality, and multivariate data sets, and feature one scalar model property such as uncertainty. Our library, named polar-diagrams, supports both continuous and categorical attributes.
Conclusion
The library can be used to quickly and easily assess the performances of complex models, such as those found in machine learning, climate, or biomedical domains.}

Abstract:

Objective:
Evaluating the performance of multiple complex models, such as those found in biology, medicine, climatology, and machine learning, using conventional approaches is often challenging when using various evaluation metrics simultaneously. The traditional approach, which relies on presenting multi-model evaluation scores in the table, presents an obstacle when determining the similarities between the models and the order of performance.

Methods:
By combining statistics, information theory, and data visualization, juxtaposed Taylor and Mutual Information Diagrams permit users to track and summarize the performance of one model or a collection of different models. To uncover linear and nonlinear relationships between models, users may visualize one or both charts.

Results:
Our library presents the first publicly available implementation of the Mutual Information Diagram and its new interactive capabilities, as well as the first publicly available implementation of an interactive Taylor Diagram.
Extensions have been implemented so that both diagrams can display temporality, multimodality, and multivariate data sets, and feature one scalar model property such as uncertainty.
Our library, named \emph{polar-diagrams}, supports both continuous and categorical attributes.

Conclusion:
The library can be used to quickly and easily assess the performances of complex models, such as those found in machine learning, climate, or biomedical domains.

Data

Location
Description

Data/
contains all datasets used in Source/main.ipynb.

Data/Dataset_0/
contains the Anscombe's quartet data set and the Datasaurus data set.

Data/Dataset_1/
contains the official, automatically generated script for downloading the CMIP3 data from the https://esgf-node.llnl.gov/projects/cmip3/. To generate the whole data set, the user should first place itself into this directory and then run the following command from the terminal sh generate_dataset_1.sh. [1]

Data/Dataset_2/
contains the data set from the subsection 3.2 Example 2 — Machine Learning Model Evaluation of our paper.

Data/Dataset_3/
contains the data set from the subsection 3.3 Example 3 — Biomedical Similarity Assertion of our paper.

[1] The script used for downloading the Dataset_1/ was generated using the tutorial found here https://esgf.github.io/esgf-user-support/faq.html#how-to-preserve-the-directory-structure.
Script can be automatically generated and downloaded again from here https://esgf-data.dkrz.de/esg-search/wget?download_structure=model&project=CMIP3&experiment=historical&ensemble=run1&variable=ts.
