New NVE metric enhances biclustering validation by assessing separability and coverage

Researchers have introduced NVE (Normalised Virtual Error), a new internal validation metric for biclustering. This metric extends the Virtual Error (VE) by incorporating a super-bicluster normalization strategy to assess the separability and redundancy of discovered biclusters. An additional variant, NVE extsubscript{cov}, further adjusts for solutions that achieve low error by selecting only small submatrices. Experiments on synthetic data and yeast gene expression datasets indicate that NVE-based measures offer valuable complementary insights beyond standard coherence metrics, particularly when considering coherence, separability, and coverage simultaneously.
