Fig. 4: The automatic medical diagnosis system using the 1M1R1C temporal kernel and the experiment results in the two sections.

a A system for diagnosing the malignancy of breast lesions, which is much simpler than in the existing method (inset in a). In this system, ultrasonic signals are applied directly to the kernel machine, so the imaging step is omitted. b V–t graph for one echo line of a benign sample (inset in Fig. 4b). c A part of the electrocardiogram of a patient with arrhythmia. Long intervals caused by abnormal beats discharged the capacitor, and the conductance of the memristor increased in the next pulse. d Five-minute temporal kernel monitoring based on the ECG of one normal patient (case 1) and two arrhythmic patients (cases 2 and 3). When arrhythmia occurred, the conductance of the memristor increased. Case 3, which had the most severe arrhythmia symptoms, showed the highest conductance.
