Description

technical field [0001] The invention belongs to the field of neural networks and relates to a configurable neural network reasoning and online learning fusion computing circuit. Background technique [0002] As an important branch of artificial intelligence, Deep Neural Network (DNN) has received great attention because it can assist or replace humans in the fields of face recognition, speech recognition, natural language processing, and medical aided diagnosis. Among them, many researchers have conducted extensive research on the reasoning and learning (training) of neural networks. The reasoning of the neural network can be regarded as further analysis and inference of the input data, and accurate inference is inseparable from the effective learning of the network parameters by the neural network. Generally, the learning of neural networks can be divided into offline learning and online learning. Offline learning only uses centralized offline data for learning, and the p...
