What are sparse labels?
Sparse labelling can be achieved either by targeting labels to specific cells, or by distributing them in a stochastic manner. Recent molecular approaches combine these two aspects, distributing markers (or combinations of markers) within genetically defined populations.
What is sparse cross entropy?
Sparse Categorical Cross-entropy and multi-hot categorical cross-entropy use the same equation and should have the same output. The difference is both variants covers a subset of use cases and the implementation can be different to speed up the calculation.
What is dense or sparse?
