File:Application of a bioinspired neuromorphic motion-cognition nerve in human activity recognition.webp

English: "a Hardware diagram of the bioinspired neuromorphic motion-cognition nerve. Information flow during the execution of the motion recognition task is illustrated. b Photograph of the flexible synaptic electronics attached to human skin. c Acceleration (Acc) and gyroscopic (Gyro) signals acquired during an activity of running. d Encoded spike trains (Acc Spike, Gyro Spike) corresponding to the bimodal motion signals (Acc, Gyro) in (c). e–j Postsynaptic current (PSC) of the synaptic transistor when a human subject performed e jumping, f rope skipping, g torso rotation, h running, i race walking, and j falling. k Visualization of two hardware outputs (mean firing rate of acceleration spikes facc, mean firing rate of gyroscopic spikes fgyro) in 2D coordinates. l Visualization of three hardware outputs (facc, fgyro, synaptic response ΔPSC) in 3D coordinates, illustrating higher-dimensional classification strategy. The data clusters in six colors correspond to different activity types. m Confusion matrix showing the results of human activity recognition."
