New theory explains missing data impact on multimodal learning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new theoretical framework to understand how missing data affects Partial Least Squares (PLS) in multimodal learning. Their analysis, based on a high-dimensional spiked model, reveals a sharp phase transition where missing entries significantly attenuate the signal strength. Above a critical threshold, the leading singular vectors become informative, allowing for recovery of latent shared structures, with the study providing formulas for this recovery. AI

IMPACT Provides a theoretical understanding of data imputation challenges in multimodal AI systems.

    Missing-Data-Induced Phase Transitions in Spectral PLS for Multimodal Learning

    arXiv:2601.21294v2 Announce Type: replace-cross Abstract: Partial Least Squares (PLS) learns shared structure from paired data via the top singular vectors of the empirical cross-covariance (PLS-SVD), but multimodal datasets often have missing entries in both views. We study PLS-…
