Energy-Efficient Spiking-CNN-Based Cross-Patient Seizure Detection
Bibliographic record
Abstract
A neuromorphic spiking convolutional neural network (SCNN) is presented for cross-patient seizure detection using multi-modal features from multi-channel electroencephalogram (EEG) data. A mixture of spectral, temporal, and spatial features is employed for building robustness against domain-specific noise/artifacts, hence boosting detection sensitivity and specificity. The feature set is converted to temporally-coded spikes before being fed to the SCNN classifier. Thanks to the asynchronous spike-based multiplier-less operation, the SCNN significantly reduces the classification computational cost without sacrificing accuracy. The developed algorithm was validated on a publicly available dataset and an average sensitivity of 83.02%, a specificity of 86.31%, and a false positive rate of 0.69/hr were achieved for cross-patient seizure detection. Our results show that a 1-bit Integer-Net leads to less than 2% drop in sensitivity compared with a 32-bit real-value resolution CNN model while offering more than 27× improvement in memory efficiency. The SCNN achieves an estimated energy efficiency of <tex>$1.28\mu\mathrm{J}$</tex> /classification, which translates into a 98.6% improvement compared to a conventional CNN implementation with the same accuracy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
