An Electrolyte‐Gated InGaZnO Phototransistor that Emulates Visual Experience‐Dependent Plasticity
Advanced Electronic Materials, EarlyView.By utilizing the light‐history‐dependent property of the IGZO electrolyte‐gated transistor, Bienenstock‐Cooper‐Munro (BCM) learning rule is successfully emulated. Moreover, the BCM learning rule enables a variety of bionic vision functions including image edge detection and associative memory, which offers a promising route for simulating high‐order ...

Unsupervised learning by a nonlinear network with Hebbian excitatory and anti-Hebbian inhibitory neurons [PDF]
arXiv, 2018 This paper introduces a rate-based nonlinear neural network in which excitatory (E) neurons receive feedforward excitation from sensory (S) neurons, and inhibit each other through disynaptic pathways mediated by inhibitory (I) interneurons. Correlation-based plasticity of disynaptic inhibition serves to incompletely decorrelate E neuron activity ...

Advanced Electronic Materials, EarlyView.An optoelectronic synaptic transistor based on core‐multi‐shell quantum dots and Pentacene achieves a recognition capability under different light intensities that closely resembles that of the human eye. Under optimal light intensity, the recognition accuracy for the MNIST dataset can reach 91.52%.
