## 📖 About
Official MetaDiT HuggingFace Repository for paper MetaDiT at AAAI 2026. This repository contains data and weights.

- `weight`: It contains weights for MetaDiT-S, surrogate model and the pre-trained spectrum encoder.
- `metadit_s_seed0_generation.zip`: Generation result of MetaDiT-S with seed 0 on our machine.
- `split_data`: Our split of the dataset, from https://github.com/SensongAn/Meta-atoms-data-sharing.
