NVE: A Separability and Coverage-Aware Internal Validation Metric for Biclustering

Paritosh Tiwari, I Navin Kumar, James C. Bezdek +1

Biclustering, or co-clustering, aims to discover coherent submatrices by grouping rows and columns of a data matrix simultaneously. This local two-dimensional structure makes valid…

Why Clipping Matters in AdaGrad? Toward a High-Probability Theory under Generalized Smoothness

Alokendu Mazumder, Ayaan Mohd, Harshit Rawat +3

We analyze the original same-step coordinate-wise AdaGrad under generalized smoothness and heavy-tailed noise with bounded variance. In this setting, local curvature may grow sub-q…

On Hamming-Lipschitz Type Stability of the Subdominant (Minmax) Ultrametric: Theory and Simple Proofs

Alokendu Mazumder, Arnab Roy, Punit Rathore

The subdominant (minmax) ultrametric is a canonical tree-structured summary of a dissimilarity matrix, arising equivalently as the ultrametric induced by single-linkage clustering.…
