Most VQA models would use some kind of Recurrent Neural Network (RNN) to process the question input
- Most VQA will use RNN to process the question input
- Easier VQA datasets shall be fine with using BOW to transport vector input to a standard (feedforward) NN
-
The standard approach to performing VQA looks something like this: Process the image. Process the question. Combine features from steps 1/2. Assign probabilities to each possible answer.
Approach to handle VQA problems:
