EQA stands for Embodied Question Answering, and is a visual question answering dataset based on House3D. After receiving a question, an agent at any position in the environment can find useful information in the environment and answer the question. For example: Q: What color is the car? In order to answer this question, the agent must first explore the environment through intelligent navigation, collect necessary visual information from a first-person perspective, and then answer the question: orange.
