Article Snippet: Time-resolved EL (TR-PSEL, fig. S20C) and Tr.-PSEL (fig. S24) measurements were accomplished by using a function generator (Keysight; 81150A) to generate a square-wave signal, a photomultiplier (Hamamatsu; H10721-01) to receive lights generated by the Cs 1− x FA x PbBr QD–based synaptic device, and an oscilloscope (Keysight; DSOX1204G) to receive the square-wave signal and light-emitting response signal of the devices.

Figure Lengend Snippet: ( A ) Cognitive-inspired MT processing with PSC and PSEL outputs for tasks 1 to 3. All matrix elements are assumed to correspond to the conductance value of the node, and the experimental electrical and optical weights of the dual-output Cs 1− x FA x PbBr 3 QD–based synaptic 8-by-8 array are used as kernels. ( B and D ) MT-CNN model configuration for tasks 1 and 2. It consists of an input layer, four PSEL/PSC convolution layers, max pooling layers, and FC layers (FC1** and FC2**). ( C and E ) MT-ResNet-15 model architecture for tasks 2 and 3. It consists of an input layer, four RB layers, three UB layers, max pooling layers, and an FC2 layer. The ResNet-7–based decoder was used to reconstruct the input image. The total loss for each configuration is determined by considering the relative ratio of regression (reconstruction) loss and classification (regression) loss, which can be used to update the weights of both the shared kernel and task-specific layers by backpropagation.
