• Title: Beyond VQA: Generating Multi-word Answer and Rationale to Visual Questions
• Authors: Radhika Dua, Sai Srinivas Kancheti and Vineeth N Balasubramanian
• Abstract summary: We introduce ViQAR (Visual Question Answering and Reasoning), wherein a model must generate the complete answer and a rationale that seeks to justify the generated answer. We show that our model generates strong answers and rationales through qualitative and quantitative evaluation, as well as through a human Turing Test.

• Abstract: Visual Question Answering is a multi-modal task that aims to measure high-level visual understanding. Contemporary VQA models are restrictive in the sense that answers are obtained via classification over a limited vocabulary (in the case of open-ended VQA), or via classification over a set of multiple-choice-type answers. In this work, we present a completely generative formulation where a multi-word answer is generated for a visual query. To take this a step forward, we introduce a new task: ViQAR (Visual Question Answering and Reasoning), wherein a model must generate the complete answer and a rationale that seeks to justify the generated answer. We propose an end-to-end architecture to solve this task and describe how to evaluate it. We show that our model generates strong answers and rationales through qualitative and quantitative evaluation, as well as through a human Turing Test.

  Programmatic VLM Evaluation (PROVE) is a new benchmarking paradigm for evaluating VLM responses to open-ended queries. We benchmark the helpfulness-truthfulness trade-offs of a range ofVLMs on PROVE, finding that very few are in-fact able to achieve a good balance between the two.

  Visual question answering (VQA) is the task of answering questions about an image. Answering the question requires commonsense knowledge, world knowledge, and reasoning about ideas and concepts not present in the image. We propose a framework that uses language guidance (LG) in the form of rationales, image captions, scene graphs, etc to answer questions more accurately.

We propose a new retriever-ranker paradigm of KB-VQA, Graph pATH rankER (GATHER for brevity) Specifically, it contains graph constructing, pruning, and path-level ranking, which not only retrieves accurate answers but also provides inference paths that explain the reasoning process.

  We introduce a new benchmark, Open-vocabulary Video Question Answering (OVQA), to measure the generalizability of VideoQA models. In addition, we introduce a novel GNN-based soft verbalizer that enhances the prediction on rare and unseen answers. Our ablation studies and qualitative analyses demonstrate that our GNN-based soft verbalizer further improves the model performance.

  Question and answer generation (QAG) consists of generating a set of question-answer pairs given a context. In this paper, we establish baselines with three different QAG methodologies that leverage sequence-to-sequence language model (LM) fine-tuning. Experiments show that an end-to-end QAG model, which is computationally light at both training and inference times, is generally robust and outperforms other more convoluted approaches.
