Researchers have introduced DiffTR, a novel unsupervised framework designed for low-rank tensor recovery across various data structures and observation processes. This approach unifies tasks such as tensor completion, denoising, and hyperspectral super-resolution by employing coordinate-conditioned diffusion. The framework utilizes shared factors, indexed by tensor coordinates, to condition a score network, enabling joint learning of factors and an implicit tensor representation from available observations. Experiments across multiple tensor modalities demonstrate competitive reconstruction quality and the flexibility of this unified conditional generative representation. AI
