I built Micro-JEPA: A lightweight JEPA (Joint Embedding Predictive Architecture) in Python

Reddit r/ArtificialInteligence Tools

Summary

Micro-JEPA is a lightweight Python implementation of the Joint Embedding Predictive Architecture (JEPA), enabling an agent to learn environment representations, predict future states in latent space, and plan actions to avoid obstacles.

I’ve always been fascinated by Yann LeCun’s vision of world models and autonomous agents, so I decided to build a minimal, lightweight implementation of a Joint Embedding Predictive Architecture (JEPA) from scratch, which I call Micro-JEPA. In this project, the agent learns a representation of the environment, predicts future states in the latent space using a learned world model, and utilizes a cost/energy function to plan its steps toward a target while actively avoiding dynamic or static obstacles. There is a video of it working in the README GitHub Repo:https://github.com/Jacopos311/Micro\_JEPA
