EMG2Pose-emg2pose

emg2pose — emg2pose Regression baseline

Meta's released regression_emg2pose.ckpt from the emg2pose benchmark, rehosted with braindecode's parameter names:

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.
