Decision Models, World Action Models, Egocentric Video

Welcome back to AI, but simple, your AI research beacon with visual explanations.

In this issue, we’ll unpack and visually explain the three directions that each gained a cluster of new papers over the past few weeks.

1. Decision models (e.g., Jev) have become their own class of model, and the open question is now whether those probabilities can be trusted.

2. World action models are now considering how much of the future the model actually needs to simulate.

3. New pipelines turn first-person (egocentric) video into 3D records of human activity that models can learn from.
