vemg2pose — emg2pose Tracking baseline

Meta's released tracking_vemg2pose.ckpt from the emg2pose benchmark, rehosted with braindecode's parameter names:

from braindecode.models import VEMG2Pose

model = VEMG2Pose.from_pretrained("braindecode/VEMG2Pose-emg2pose-tracking")

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="lstm", parameterization="velocity". The recurrent decoder emits one velocity per joint, integrated from a supplied initial pose. Call model(x, y0); this checkpoint was trained with the 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.
