The source addresses the critical limitations in evaluating single-cell profile embeddings, which are widely used for characterizing cell types and states in biological investigations. To demonstrate the incompleteness of existing quality assessment metrics, the researchers introduce a model called Islander, a three-layer perceptron that outperforms established integration methods on standard metrics but severely distorts actual biological structures by creating separate cell "islands." This flaw reveals that current evaluation methods, such as those within the scIB framework, prioritize…
