Researchers have introduced StrADiff, a novel framework for unsupervised blind source separation that handles both linear and nonlinear mixtures. This method treats each latent dimension as a separate source branch, employing an individual adaptive reverse diffusion process for each. StrADiff optimizes source-wise generation, structural regularization, and observation-space reconstruction jointly, enabling direct recovery of latent sources from observed mixtures without requiring supervised labels or post-processing.
