Description

Hi!

I was playing a bit with spikecomponents, and I was wondering if someone was already working on it, or if it could be worth it that I add a clustering class (https://github.com/SpikeInterface/spikeinterface/blob/main/src/spikeinterface/sortingcomponents/clustering/method_list.py), with UMAP as a dimensionality reduction method. Indeed, this thesis shows that UMAP is promising https://dalspace.library.dal.ca/handle/10222/83717 if we manage to compute it efficiently.

Best,

Florent

Research direction

Start by reading src/spikeinterface/sortingcomponents/clustering/method_list.py and examining how dimensionality-reduction methods are currently represented. Assess the proposed UMAP approach, including whether its computation can be efficient enough for spikecomponents. Done means the project has a defined UMAP method and an agreed way to evaluate its practicality.
