-Mnist World dataset for experiments of FloWM: https://huggingface.co/papers/2601.01075.
+# MNIST World Dataset
+
+This repository contains the **MNIST World** dataset, used for experiments in the paper [Flow Equivariant World Models: Memory for Partially Observed Dynamic Environments](https://huggingface.co/papers/2601.01075), accepted at ICML 2026.
+
+MNIST World is a 2D partially observed video world modeling benchmark designed to evaluate how well models can handle smooth, time-parameterized symmetries and unobserved regions that continue to evolve.

+
+## Dataset Configurations
+
+The dataset is provided in several configurations to test different aspects of world modeling:
+
+- **`dynamic_po`**: Partially observed environments with dynamic elements (the main benchmark for the paper).
+- **`static_po`**: Partially observed environments where the world is static.
+- **`dynamic_fo`**: Fully observed environments with dynamic elements.
+- **`dynamic_fo_no_sm`**: Fully observed environments with dynamic elements but no self-motion.
+
+Each configuration includes `train` and `validation` splits.
