 # Visual Question Answering in Tensorflow

 This is a Tensorflow implementation of the VIS + LSTM visual question answering model from the paper [Exploring Models and Data for Image Question Answering][1]
 by Mengye Ren, Ryan Kiros & Richard Zemel. The model architectures vaires slightly from the original - the image embedding is plugged into the last lstm step (after the question) instead of the first. The LSTM model uses the same hyperparameters as those in the [Torch implementation of neural-VQA][2].
