Multi-step prediction in linearized latent state spaces for representation learning

Andrii Tytarenko • Sistemnì Doslìdženâ ta Informacìjnì Tehnologìï (2022)

In this paper, we derive a novel method as a generalization over LCEs such as E2C. The method develops the idea of learning a locally linear state space by adding a multi-step prediction, thus allowing for more explicit control over the cur...
