Bayesian Tensor Decomposition with Diffusion Model Prior

arXiv:2606.03212v1 Announce Type: new Abstract: Low-rank tensor decomposition (TD) is usually effective on clean, fully observed data, but it often degrades under severe missingness or noise. Low-rankness is itself a useful but limited structural prior, and additional handcrafted priors (e.g., sparsity or smoothness) still fall short of capturing the rich statistics of real-world data. To compensate for this weak inductive bias under heavy corruption, one would like to inject a learned, data-driven prior; however, the state-of-the-art diffusion models are not readily compatible with current TD

Why this matters
Why now

This paper represents a current effort in AI research to overcome limitations of traditional low-rank tensor decomposition by integrating advanced data-driven priors from diffusion models.

Why it’s important

Improving tensor decomposition with machine learning techniques could lead to more robust AI models operating on incomplete or noisy real-world data, enhancing performance in various applications.

What changes

The ability to integrate diffusion models into tensor decomposition signifies a potential advancement in handling complex data, perhaps making AI systems more resilient to real-world imperfections.
