[0080] The present invention will be further described below in conjunction with the drawings.
[0081] Such as figure 1 As shown, the text recognition method based on the attention mechanism and the connection time classification loss of the present invention, the specific implementation steps are as follows:
[0082] S1: Collect the data set. Collect texts in various natural scenes and merge these texts. The data set is divided into three parts: training data set, verification data set, and test data set. In order to ensure that the training set, the validation set and the test set have the same sample distribution, the original data set is first shuffled, and then divided according to the proportion, the division ratio is 7: 2: 1. The training data set is used as optimization model parameters, the verification data set is used as model selection, and the test data set is used as the final evaluation of the model. Denote the selected data set as T={(x 1 ,y 1 ),(x 2 ,y 2 ),…,(...
