Elapsed headband label duration reduced mean sleep stage log loss under fixed tables in 50 BOAS v1.1.3 test people

Elapsed headband label duration improved sleep stage probability scores in 50 BOAS v1.1.3 test people. The rule used the current and earlier stored headband labels. We fitted fixed tables on 50 other people. Mean person log loss fell from 0.5374 to 0.4993 nats per valid epoch. The gain was 0.0381 nats, with a 95% person bootstrap interval of 0.0253 to 0.0431. Both tables were fitted again in each draw. Gain occurred in 47 of 50 test people. All 60,417 hard stage predictions stayed the same. Six planned checks also had positive gains. The package has the source bytes, fixed split, local plan, fitted tables, epoch results, draw indices, code, and hash checks. A fresh source download and a full numerical repeat matched the archive. The cohort had been studied before. Original AI folds were not available. These results do not establish use on new cohorts or live signals.

We used the archived BOAS v1.1.3 source files, hash manifest, and exact 50-person training and test split. Its fixed Markov result motivated a direct test of elapsed stored label duration.

We read the joint device label table report before the local plan. It informed the probability table design. The present rule uses current headband labels and their elapsed duration.
