Researchers have analyzed the training dynamics of energy-based learning models, which are known for their non-convexity and potential for poor local optima. Their work introduces the concept of an "effective model" to understand this process, revealing that learning strictly positive distributions can lead to both accurate data-consistent points and spurious, non-matching fixed points. The study also demonstrates a hierarchical learning process where lower-order interactions are prioritized over higher-order ones, offering a mechanistic explanation for the observed distributional simplicity bias in these models.
