• Authors: Aditya Kane, V Manushree, Sahil Khose
• Abstract summary: Visual Question Answering (VQA) is a multi-modal task that involves answering questions from an input image. Main challenge is the delay caused by the generation of labels in the assessment of the affected areas. We deploy pre-trained CLIP model, which is trained on visual-image pairs. We surpass previous state-of-the-art results on the FloodNet dataset.

• Abstract: Visual Question Answering (VQA) is a multi-modal task that involves answering questions from an input image, semantically understanding the contents of the image and answering it in natural language. Using VQA for disaster management is an important line of research due to the scope of problems that are answered by the VQA system. However, the main challenge is the delay caused by the generation of labels in the assessment of the affected areas. To tackle this, we deployed pre-trained CLIP model, which is trained on visual-image pairs. however, we empirically see that the model has poor zero-shot performance. Thus, we instead use pre-trained embeddings of text and image from this model for our supervised training and surpass previous state-of-the-art results on the FloodNet dataset. We expand this to a continual setting, which is a more real-life scenario. We tackle the problem of catastrophic forgetting using various experience replay methods.

We also justify the validity of the class imbalance interpretation scheme on other computer vision tasks, such as face recognition and image classification.

  Visual Question Generation (VQG) is the task of generating natural questions based on an image. In this paper, we try to exploit the different visual cues and concepts in an image to generate questions using a variational autoencoder (VAE) without ground-truth answers. Our approach solves two major shortcomings of existing VQG systems: (i) minimize the level of supervision and (ii) replace generic questions with category relevant generations.
