New paper proposes precision-recall metrics for dimensionality reduction validation

A new paper introduces a precision-recall framework to evaluate dimensionality reduction (DR) techniques, specifically focusing on how well they preserve cluster structures in data visualizations. The proposed metrics assess the relationship phase of DR, quantifying the alignment between modeled similarities and expected cluster labels. This approach aims to accelerate hyperparameter tuning, identify projection artifacts, and confirm if underlying cluster structures are captured, thereby making the DR process more efficient and reliable.

    Why Can't I See My Clusters? A Precision-Recall Approach to Dimensionality Reduction Validation

    arXiv:2509.04222v2 Announce Type: replace Abstract: Dimensionality Reduction (DR) is widely used for visualizing high-dimensional data, often with the goal of revealing expected cluster structure. However, such a structure may not always appear in the projections. Existing DR qua…
