MVQAS

Abstract

This paper demonstrates a medical visual question answering (VQA) system to address three challenges: 1) medical VQA often lacks large-scale labeled training data which requires huge efforts to build; 2) it is costly to implement and thoroughly compare medical VQA models on self-created datasets; 3) applying general VQA models to the medical domain by transfer learning is challenging due to various visual concepts between general images and medical images. Our system has three main components: data generation, model library, and model practice. To address the first challenge, we first allow users to upload self-collected clinical data such as electronic medical records (EMRs) to the data generation component and provides an annotating tool for labeling the data. Then, the system semi-automatically generates medical VQAs for users. Second, we develop a model library by implementing VQA models for users to evaluate their datasets. Users can do simple configurations by selecting self-interested models. The system then automatically trains the models, conducts extensive experimental evaluation, and reports comprehensive findings. The reports provide new insights into the strengths and weaknesses of selected models. Third, we provide an online chat module for users to communicate with an AI robots for further evaluating the models. The source codes are shared on https://github.com/shyanneshan/VQA-Demo.
