New research details theoretical limits of Partial Least Squares in multi-modal learning

A new paper published on arXiv provides a rigorous random matrix theory analysis of spiked cross-covariance models, which are relevant to multi-modal learning and Partial Least Squares (PLS). The research identifies specific thresholds for the emergence of informative components and reveals a fundamental performance gap between PLS and optimal estimators. The findings clarify the theoretical limits of PLS and offer guidance for developing reliable multi-modal inference methods in high-dimensional settings. AI
