# TEDBench — Supervised from scratch (structure only)
**Variant:** `miae_l` | **Parameters:** 339M | **Layers:** 24 | **Hidden dim:** 1024 | **Attn heads:** 16
This **MiAEClassifier** was trained from scratch on TEDBench without pretraining. It is part of the research presented in the paper [Protein Fold Classification at Scale: Benchmarking and Pretraining](https://arxiv.org/abs/2605.18552).
MiAE is an SE(3)-invariant masked autoencoder that masks up to 90% of backbone frames and reconstructs the full structure with a lightweight decoder. It establishes a strong recipe for protein fold classification on the [TEDBench](https://github.com/BorgwardtLab/TEDBench) benchmark.
## 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
```python
from tedbench.utils.io import load_from_hf
model = load_from_hf("TEDBench/miae-l-sc")
model.eval()
```
### From a Lightning checkpoint
```python
from tedbench.model import MiAEClassifier
model = MiAEClassifier.load_from_checkpoint("model.ckpt", weights_only=False)
model.eval()
```
