In recent years, machine learning has been widely used in image recognition while conventional models such as linear classifiers, K-nearest neighbors, non-linear classifiers, and Support Vector Machines (SVM) all require a large number of training samples to train the model to achieve good results. Previous researches on handwritten numerals recognition in Tibetan also need a large number of training samples to train the model. Therefore, this paper conducts training and recognition research on TextCaps model proposed by Vinoj Jayasundara et al., by using Tibetan handwritten numerals data set with a few training samples. In this paper, the training samples of 200 tags for each class are used to add random noise to the original image instantiation parameters and generate new image data sets through the Capsule Network (CapsNet) and its decoder network to achieve the purpose of data expansion. Finally, the character images are classified by the a new model.
