Latent world models allow agents to reason about complex environments with
high-dimensional observations. However, adapting to new environments and
effectively leveraging previous knowledge remain significant challenges. We
present variational causal dynamics (VCD), a structured world model that
exploits the invariance of causal mechanisms across environments to achieve
fast and modular adaptation. By causally factorising a transition model, VCD is
able to identify reusable components across different environments. This is
achieved by combining causal discovery and variational inference to learn a …
