| # emg2pose — emg2pose Regression baseline |
|
|
| Meta's released `regression_emg2pose.ckpt` from the |
| [emg2pose benchmark](https://github.com/facebookresearch/emg2pose), rehosted with |
| [braindecode](https://braindecode.org)'s parameter names: |
|
|
| ```python |
| from braindecode.models import VEMG2Pose |
| |
| model = VEMG2Pose.from_pretrained("braindecode/EMG2Pose-emg2pose") |
| ``` |
|
|
| 16-channel sEMG at 2 kHz in, 20 joint angles per sample out. The encoder uses **valid** |
| convolutions and consumes a left context of **1790** samples, so windows must be longer |
| than that; the paper trains on 11,790 (10,000 + 1790). |
|
|
| ## Configuration |
|
|
| `decoder="mlp"`, `parameterization="position"`. The stateless MLP decoder reads the pose out directly at each step, still conditioned on the previous pose. Trained without a ground-truth initial pose. |
|
|
| ## Provenance |
|
|
| Not retrained — the authors' checkpoint with parameter names rewritten. Loaded into |
| `braindecode.models.VEMG2Pose` and run against the reference `emg2pose.pose_modules` |
| implementation on the same input, the outputs are **bit-identical** (max absolute |
| difference 0.0), with all 68 tensors mapped. |
