Abstract: In this paper, the recognition algorithm of handwritten numerals is studied based on deep learning stack Auto-Encoder neural network and full connection layer. The Auto-Encoder neural network can mine the internal information of data and extract effective features; all connection layers are classified for prediction. Compared with traditional machine learning methods such as SVM and Random Forest, the MINIST dataset and college students’ handwritten digit dataset have achieved better results with an accuracy of 0.967. The algorithm designed in this paper provides a research basis for the application prospect of stacked Auto-Encoder neural networks.
