Unpaired Joint Distribution Modeling via Multi-Scale Image Representations
Yihang Zou, Hui Zhang, Zuowei Shen, Chenglong Bao
This paper studies the problem of learning a joint distribution from marginal observations, which is inherently ill-posed due to the ambiguity of feasible couplings. We propose LUD-MSR, a latent-variable probabilistic framework that models the joint distribution via auxiliary rep…
