Transfer learning is commonly used in computer vision, we want to apply it on visual question answering. We build up a QA pre-trained model to extract QA features from different source datasets and finally find the optimal pre-training for next experiments. We select LSTM model as our QA pre-train model since LSTM could fit different length of questions and has the same structure as our baseline model. We also do experiments on VQA baseline with LSTM+CNN model and pre-train + CNN model on different scales of datasets to find out the effectiveness of transfer learning. We figure out that baseline + pre-train models with different features have different influence. At last, we build up a VQA model with attention mechanism to combine QA pre-train features and image pre-train features, and studied its application in ocean image processing.
