Description: A set of convolutional neural networks (CNNs) and recurrent neural networks (RNNs) were configured to perform the text recognition task using SROIE data set. Features produced from CNN-RNN models were interpreted to the text using an attention mechanism. We further process the data using a language model (LM) to find the best answer.

Description: We mainly completed the task 2 using CRNN. Different from the content in the paper, we modified the structure of CNN to PVANet-like and used multiple GRU layers. And we adjusted the training strategy to continue to improve the recognition result.
