Support-CSP support-feature 標準化對照
共同 8 通道；中榮採 IIR-only event 2–4 秒，正常人／患者採同型 IIR-only event 0–2 秒。
唯一比較因子：Support CSP log-variance feature 是否套用
(F - μ_support) / σ_support。兩條件使用相同 support/query fold、low-trial selection、target initialization seed；各自使用相同 34 位來源受試者重新預訓練的 base model。限制：中榮 9 個 unit 是 2 位受試者的不同日次，僅作 session-level 描述；不能當作 9 位獨立受試者的群體推論。
結果判讀
- 沒有穩定證據支持 support feature z-score：六個 dataset × trial-setting 的 paired bootstrap 95% CI 都跨 0。
- 低 Trial：正常人 z-score 對 raw 為 +1.06 pp（CI [-0.48, 2.64]）；患者為 +0.80 pp；中榮反而為 -0.98 pp。
- 工程結論：保留 z-score 並不會造成明顯傷害，但目前沒有足夠理由把它視為模型提升來源。後續 CSP 改良應優先看頻帶、support trial 品質或 prototype 設計，而不是這個 feature scaling 開關。
