Critical Difference Diagrams
This repository contains the necessary code to generate a critical difference diagram based on the Wilcoxon-Holm method to detect pairwise significance.
Result
By running the python3 main.py you will generate a critical difference diagram with Wilcoxon-Holm post-hoc analysis for the data present in the example.csv file.
First the Friedman test is performed to reject the null hypothesis, we then proceed with a post-hoc analysis based on the Wilcoxon-Holm method.
We can clearly see how on average clf3 and clf5 were the best algorithms over the 15 datasets.
A thick horizontal line groups a set of classifiers that are not significantly different.

In this paper we used the critical difference diagram to compare the recent deep learning models for time series classification where we evaluated 9 different architectures on 85 different datasets from the UCR/UEA archive.

Deep Neural Network Ensembles for Time Series Classification
In this paper we used the critical difference diagram to show how ensembling hybrid architectures will allow deep learning models to reach even better accuracy when evaluated on 85 different datasets from the UCR/UEA archive.
