Task: Question Answering
Input (English): The encoder is a Convolutional Neural Network (CNN) and the decoder is a Long Short-Term Memory (LSTM) network, as presented in Figure 2 . The image is passed through the encoder generating the image representation that is used by the decoder to know the content of the image and generate the description word by word. 
 Question: What model is used to encode the images?
Output (English): a Convolutional Neural Network (CNN)
