We descrive a very simple bag-of-words baseline for visual question answering. The description of the baseline is in the arXiv paper http://arxiv.org/pdf/1512.02167.pdf. The code is developed by Bolei Zhou and Yuandong Tian.

Demo is available at http://visualqa.csail.mit.edu/

To train the model using the code, the following data of the VQA dataset are needed:

• The pre-processed data of text is at http://visualqa.csail.mit.edu/data_vqa_txt.zip
• The googlenet feature of all the COCO images is at http://visualqa.csail.mit.edu/data_vqa_feat.zip

The pre-trained model used in the paper is at http://visualqa.csail.mit.edu/coco_qadevi_BOWIMG_bestepoch93_final.t7model. It has 55.89 on the Open-Ended and 61.69 on Multiple-Choice for the test-standard of COCO VQA dataset.
