Experiment 011 · Two pretrained EEG encoders
Research Note 011 compares two independently pretrained continuous EEG encoders on identical public around-ear EEG inputs.
- 122 selected 30-second blocks; five paired people and 110 primary blocks.
- 610 new CBraMod forwards and 610 reused CodeBrain outputs, with exact input/output hashes.
- Mean paired original-minus-phase contrast: geometry 0.0713; change profile 0.0947. Both adjusted p values are 0.125. These findings are inconclusive and do not establish universal tokens or semantic brain meaning.
- No additional source people or recorded hours. Reserved people and later sessions remain untouched.
The data archive includes the captured source/input layout, selected numerical waves, both latent archives, full candidate and analysis ledgers, frozen protocol, retained corrections, and independent review. Full raw recordings and model weights remain upstream. Extract into a new directory and follow the included README; offline reproduction requires no model call.
Independent review accepted every shipped source/report/data hash. A fresh final extraction reproduced scientific values and SQLite table contents; file headers can vary with SQLite versions. Verify the assets against SHA256SUMS-v0.7.0.txt.
