Figure 6

Simulation of neural network based on WSe2 QDs device. (a) A three-layer neural network structure is shown. It contains input layer, hidden layer and output layer. (b) Image representation of some handwritten digits in the MNIST dataset. (c) The comparison between the recognition accuracy of the optical recognition dataset of handwritten digits in the neural network simulation and the ideal case. After 40 training sessions, the ideal case recognition accuracy reaches 96.71%, and the device-based recognition accuracy reaches 91.59%. (d) Regarding the comparison of the recognition accuracy of the MNIST dataset in the neural network simulation with the ideal case, after 40 training sessions, the ideal case recognition accuracy reaches 98.19%, and the device-based recognition accuracy reaches 94.05%.
