通过生成未来视角图像语义来提升视觉 - 语言导航能力（英文版）

英文标题：Improving Vision-and-Language Navigation by Generating Future-View Image Semantics中文摘要：该研究旨在探讨智能体是否可以在导航的同时生成未来视图的语义，并通过三个代理任务和一项辅助损失来教授模型实现该目的；实验表明这种能力使智能体的性能得到了提升，并且学习如何预测未来视图语义使智能体对于长路径的表现更好。英文摘要：Vision-and-Language Navigation (VLN) is the task that requires an agent tonavigate through the environment based on natural language instructions. Ateach step, the agent takes the next action by selecting from a set of navigablelocations. In this paper, we aim to take one step further and explo
