Researchers have developed a new PAC-Bayesian framework to provide generalization guarantees for Variational Autoencoders (VAEs) when applied to time series data. This framework extends existing PAC-Bayesian guarantees to models with Markovian latent structures, effectively capturing temporal dependencies without the guarantees growing with the length of the data trajectory. The proposed bounds rely on assumptions common in the field, and the authors demonstrate their applicability in a specific example. AI
