percom-experiments

Use when designing or auditing IEEE PerCom empirical evaluations, covering real human subjects, leave-one-subject-out / cross-subject evaluation, F1 and event-level metrics on imbalanced activity classes, deployment realism (free-living vs. lab), fair baselines, contamination-aware model ablations, and matching evidence to the shape of each pervasive-computing claim.

# PerCom Experiments

Use this before submission when the evaluation is not yet locked. PerCom reviewers are ubicomp
empiricists; the evaluation is where a sensing idea is won or lost, and — because the review is a
single round with a bounded rebuttal — **the evaluation must be complete at submission** (you
cannot add experiments in the rebuttal). The organizing principle is **evidence proportional to the
claim**, tested on **people and conditions a skeptic would accept**.

## Evaluation audit

- **Evaluate cross-subject by default.** A recognition claim about *users* needs
  **leave-one-subject-out** (or leave-one-session-out) results, not a pooled split that lets the
  same person appear in train and test. Within-subject numbers are a supporting detail, never the
  headline.
