Researchers have identified a sharp computational phase transition in the task of learning-to-sample for Ising models. They constructed a family of Ising models where learning-to-sample becomes computationally hard, even with access to samples and parameters. This finding establishes a distinct boundary between tractable and intractable learning scenarios for generative modeling, suggesting that learning-to-sample can be more difficult than parameter learning.
