Reference issue

Closes issue #290

Type of change

This is my sprint 1 PR with a tutorial notebook on task alignment using a supervised iterative method, based on the ICP algorithm (https://ieeexplore.ieee.org/document/121791). The tutorial notebook is based on #389, since the effectiveness of both domain adaptation algorithms is validated using the same xor-rxor experiment.

What does this implement/fix?

The approach of aligning tasks is different from the CPD method, since this method uses supervision to find a suitable rigid affine registration that aligns the classes + the point distribution. The CPD method only aligns the point distribution without information about classes, which is sufficient for improving BTE (as shown by high BTE in xor-nxor experiment).

@ykobaya9 here is a list of what needs to be addressed in order:

  • Remove empty cell in the notebook
  • Markdown your title with "#" instead of "##" reserved for subtitles
  • Unify names of tutorial and function file, and I recommend xor_rxor_with_icp. Is it rxor or nxor?
  • Add the updated name to a proper place in tutorials.rst
