Morph an input dataset of 2D points into select shapes, while preserving the summary statistics to a given number of decimal points through simulated annealing. It is intended to be used as a teaching tool to illustrate the importance of data visualization. python animation simulated-annealing summa...

As a result, it is typical for the first table (“Table 1”) of a research paper to include summary statistics for the study data. Our objectives are 2-fold. First, we seek to provide a simple, reproducible method for providing summary statistics for research papers in the Python ...

In python, you can useshaplibraries to understand how much each input variable in the machine learning model contributes to the model prediction. But, I'm not able to have that flexibility in MATLAB. Ref:https://towardsdatascience.com/explain-your-model-with-the-shap-values-bc36aac4de3d ...
