Abstract: A training system, a training method, and a recognition system are provided. The training method is used to train a neural network module including: an encoder module, a shared decoder module, a synthesis module, and a classification module. The training method includes performing in a training epoch: repeatedly executing: taking a training image from a training set as an input image, obtaining a first loss based on training feature images of the training image and the feature images corresponding to the training image, and obtaining a second loss based on a classification marker of the training image and a classification generated by the classification module in correspondence with the training image; and updating first parameters and second parameters based on an average value of all the first losses and an average value of all the second losses obtained in the preceding step and an update algorithm.
