Documented resultValidated EEG → FRP pipelinePreprocessing / FRP pipeline validation (local research; completed): 19 EEG channels; delta/theta/alpha/beta/gamma filtering; non-overlapping 1-second seizure windows; per-segment AMI/FNN and signal-dependent fuzzy threshold; phase-space reconstruction and fuzzy C-means. Selected annotated TUSZ recordings. Four-class segment discrimination remains challenging; accuracy is modest across bands. MYSZ has only one patient and is excluded from the patient-separated pilot. Only five held-out test patients; initial generalization pilot, not a definitive cross-patient performance estimate. Segment and patient results are not directly comparable: class sets, evaluation units and split strategies differ. Controlled CNN-vs-Swin patient-separated comparison is ongoing/planned; it has no supplied completed results. Internal Biomedical Sensors and Systems Lab, University of Memphis research; no public repository, publication URL or stable external artifact link is supplied.
