Learn world models by building them: from the intuition behind latent dynamics to a working simulation, planning, and evaluation system.
Caution
Structured learning path with lecture and project cards.
Concept-first explanations with mermaid diagrams and background callouts for deep-learning readers.
Seven architecture families, three planning mechanisms, side-by-side comparison tables.
Five lectures and five projects that take you from the intuition behind world models to a working three-model evaluation dashboard.
| # | Type | Title | Core Topics |
|---|---|---|---|
| L01 | Lecture | Internal Simulation & Historical Context | Craik's mental models, predictive coding, four eras of world model evolution |
| L02 | Lecture | Observation Encoding & Latent Dynamics | VAE, CNN encoder, ELBO, GRU → MDN-RNN → RSSM |
| L03 | Lecture | Architecture Patterns, Learning Paradigms & Planning | Seven architecture families, CEM-MPC, latent Actor-Critic, TD-MPC |
| L04 | Lecture | Evaluation by World Model | FID, reward correlation, consistency loss, PSNR, horizon drift |
| L05 | Lecture | Frontier Debates | Language vs physical grounding, Bitter Lesson, AGI as a research target |
| P01 | Project | Train a VAE Encoder | Small CNN VAE on 64×64 pixels; ELBO loss curve; latent slider visualization |
| P02 | Project | Build an RSSM Dynamics Model | GRU, MDN-RNN, and RSSM compared; prior vs posterior rollout plots |
| P03 | Project | Train a Dreamer Agent | Full training loop: encoder + RSSM + latent Actor-Critic on a small pixel env |
| P04 | Project | Swap the Dynamics Backbone | Replace RSSM with a small causal Transformer (STORM-style); architecture comparison |
| P05 | Project | World Model Evaluation Dashboard | Per-model metrics side by side: FID, reward correlation, PSNR, latent drift |

You do not need to finish all theory before starting a project. Build, then come back with questions.
