Baseline CSP classifiers achieve approximately 61.5% / 61.7% mean session-wise LOSO accuracy. Baseline CSP + LDA and CSP + linear SVM mean LOSO accuracy.
Documented resultBaseline CSP classifiers achieve approximately 61.5% / 61.7% mean session-wise LOSO accuracyMotor imagery baseline LOSO (local research; completed): 8–30 Hz filtering; cue-locked epochs -1.0 to 4.0 s, baseline -1.0 to 0.0 s, classification window 0.5 to 3.5 s. Fit CSP on training folds only. Subject-wise Leave-One-Session-Out across R04, R08 and R12, avoiding random trial splits. PhysioNet EEG Motor Movement/Imagery: clean 106-subject baseline, sessions R04, R08 and R12. Baseline CSP + LDA LOSO accuracy: ~61.5%. Baseline CSP + LDA; reported mean research LOSO accuracy. PhysioNet EEG Motor Movement/Imagery: clean 106-subject baseline, sessions R04, R08 and R12. Within-subject Leave-One-Session-Out (R04, R08, R12). Not a clinical or held-out-subject result. Baseline CSP + linear SVM LOSO accuracy: ~61.7%. Baseline CSP + linear SVM; reported mean research LOSO accuracy. PhysioNet EEG Motor Movement/Imagery: clean 106-subject baseline, sessions R04, R08 and R12. Within-subject Leave-One-Session-Out (R04, R08, R12). Not a clinical or held-out-subject result. Research workflows and benchmarks, not clinical diagnostic systems or production medical devices. S088, S092 and S100 were excluded because their 128 Hz recordings differed from the expected 160 Hz; the clean baseline contains 106 of 109 audited subjects. LOSO means Leave-One-Session-Out within subjects across R04, R08 and R12, not leave-one-subject-out or clinical performance. Tuning cohort size and uncertainty estimates are not separately supplied. Tuning yielded only about 1–1.2 percentage points of reported mean LOSO improvement; subject/session non-stationarity remained a larger constraint than classifier choice alone.
Tuned CSP classifiers achieve approximately 62.7% / 62.4% mean session-wise LOSO accuracy. Tuned CSP + LDA and CSP + linear SVM mean LOSO accuracy; no inferred tuning cohort size.
