A meeting point for two predictive traditions

World models and joint-embedding predictive architectures (JEPA) start from a simple premise: intelligence rests on internal models that predict how the world evolves — learned in abstract representation spaces rather than raw pixels or measurements.

Physics has built predictive models of the world from first principles for centuries. This workshop asks what these two traditions can learn from each other. Can self-supervised, joint-embedding methods recover physical structure — symmetries, conservation laws, dynamics — directly from data? Can physical priors make world models more sample-efficient, interpretable, and reliable?

Over five days at the Aspen Center for Physics, roughly seventy researchers from machine learning and the physical sciences work through these questions in focused morning sessions and long, unstructured afternoons built for collaboration.

“The world is predictable in the right coordinates. The open question is whether a model can learn those coordinates on its own.”

Themes

T1

Joint-embedding prediction

JEPA and self-supervised representation learning as a route to abstract, predictive features.

T2

World models & latent dynamics

Learning state spaces, rollouts, and model-based planning over learned representations.

T3

Symmetry & physical priors

Conservation laws, equivariance, and geometry as inductive biases for learning.

T4

Foundation models for science

Large pretrained models for physics, astronomy, and the natural sciences.

T5

Emergence & interpretability

What physical structure emerges in learned dynamics, and how to read it.

T6

Predictive vs. generative

Energy-based and predictive objectives against generative modeling in latent space.

Program

Participants arrive Sunday, February 28, with an evening welcome reception; sessions run Monday through Friday. Afternoons are deliberately kept open — the Aspen tradition of unstructured time for collaboration, working groups, and the occasional ski. Confirmed speakers appear below; additional speakers and the detailed schedule will be announced.

Venue

The workshop is hosted at the Aspen Center for Physics, an independent institution that has convened physicists for focused, collaborative research since 1962. Its format — short mornings, open afternoons, no distractions — is the reason the meeting is structured the way it is.

Aspen sits at 2,400 m in the Elk Mountains of Colorado. Late February is deep winter: bring layers. Lodging and travel guidance will be shared with registered participants.
