Unlike previous machine learning models, the hybrid network handles variable-length sequences and does not need to segment characters from plates. The application experiments with a model of hybrid network, evaluates its correct predictions on the validation set by BLEU scores, and compares it with the model of K-nearest neighbors and the model of Support vector machines. Estimated BLEU scores show that the model of hybrid network gives a reliable accuracy, and this result is better than that of two machine learning models.
