New Classifier Discrimination Score (CDS) improves single-cell perturbation evaluation

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced a new evaluation metric called the Classifier Discrimination Score (CDS) for single-cell perturbation data, addressing limitations in traditional per-cell accuracy metrics. This new score averages classifier probability vectors over entire populations, enabling more reliable identification of true perturbations even with overlapping cell classes. CDS demonstrates superior performance over existing methods like the Perturbation Discrimination Score (PDS), particularly when cell data is scarce, and offers a more robust way to compare perturbation models.
