# TEDBench — Pretrained autoencoder (structure only)

**Variant:** `miae_b`  |  **Parameters:** 102M  |  **Layers:** 12  |  **Hidden dim:** 768  |  **Attn heads:** 12

This repository contains the **pretrained MiAE-B** (base) checkpoint, a self-supervised model for protein structure representation learning introduced in the paper [Protein Fold Classification at Scale: Benchmarking and Pretraining](https://huggingface.co/papers/2605.18552). 

MiAE (Masked Invariant Autoencoders) is an $\mathrm{SE(3)}$-invariant autoencoder that uses an extremely high masking ratio (up to 90%) of backbone frames to reconstruct full protein structures. It can be used as a feature extractor or as the starting point for fine-tuning on protein fold classification tasks.

- **Authors:** Dexiong Chen, Andrei Manolache, Mathias Niepert, Karsten Borgwardt

## Architecture sizes

| Variant | Params | Layers | Hidden dim | Attn heads |
|---------|-------:|-------:|-----------:|-----------:|
| `miae_s` | 29 M | 6 | 512 | 8 |
| `miae_b` | 102 M | 12 | 768 | 12 |
| `miae_l` | 339 M | 24 | 1 024 | 16 |

Append `+model.use_seq_input=true` to `miae_b` for the **+seq** variant.

## Usage

### Load from the HuggingFace Hub

Using the `tedbench` library:

```python
from tedbench.utils.io import load_from_hf

model = load_from_hf("TEDBench/miae-b")
model.eval()
```

### From a Lightning checkpoint

```python
from tedbench.model import MiAE

model = MiAE.load_from_checkpoint("model.ckpt", weights_only=False)
model.eval()
```
