# HPC-MEC World Model

This repository hosts pretrained checkpoints for **Structure Abstraction and Generalization in a Hippocampal-Entorhinal Inspired World Model**.

The model is a hippocampal-entorhinal inspired world model that learns reusable transition structures from observation-only videos. It separates content-rich episodic representations from compact abstract dynamics, and uses velocity-like latent transitions for prediction and structural generalization across objects and scenes.
