Hardware architectures and chip micrographs of ML-embedded neural prostheses for epilepsy: (a) Linear dual-detector SVM classifier and closed-loop transcranial neurostimulator [13], (b) non-linear SVM-based seizure detector [14], (c) linear least square (LLS) classifier and closed-loop stimulator [17], (d) ridge regression classifier (RRC) and closed-loop stimulator [88]. (e) Gradient-boosted tree ensemble for seizure detection [12], (f) exponentially decaying-memory SVM and closed-loop stimulator [16], (g) AdaBoost decision tree classifier and closed-loop stimulator [29], (h) two-level coarse/fine classifier and closed-loop stimulator [89].
