Backpropagation Through DBSCAN #7

Closed M-Hammod closed 4 months ago

Thank you so much for sharing your work, it's awesome, Could you please help me understand how the backpropegation through DBSCAN works?

Thank you for your question.

DBSCAN isn't differentiable, hence backpropagation doesn't apply directly to DBSCAN. It is one of the improvements that could be applied to RaTrack by replacing DBSCAN with differentiable clustering.
