@charlotte-pel is this still relevant up-to-date?

I think it is an interesting feature. Does that cost a lot to compute the confusion matrix?
It might be computed easily on the load method defined in notebooks/Evaluation.ipynb.
And the confusion matrices might be concatenate in a 3D array, in the load_table method and return (with the variable table).

But feel free to close this issue if you don't find it crucial.
