📝 摘要（中文）
构建能够在任意3D环境中遵循任意语言指令的具身AI系统是实现通用AI的关键挑战。SIMA项目通过训练代理在多样化的虚拟3D环境中执行自由形式的指令，旨在开发一种能够在任何模拟3D环境中完成任何人类可执行任务的指令代理。该方法专注于语言驱动的通用性，允许代理实时与环境交互，输入为图像观察和语言指令，输出为键盘和鼠标动作。本文描述了我们的动机、目标、初步进展及在多种研究环境和商业视频游戏中的初步结果。
🔬 方法详解
问题定义：本论文旨在解决具身AI系统在复杂3D环境中执行语言指令的能力不足，现有方法通常依赖于特定环境或任务，缺乏通用性和适应性。
核心思路：SIMA项目的核心思想是训练代理在多种虚拟3D环境中执行自由形式的语言指令，强调通过图像观察和语言输入来驱动代理的行为，从而实现更高的通用性和灵活性。
技术框架：整体架构包括三个主要模块：环境感知模块（处理图像输入）、语言理解模块（解析语言指令）和行为执行模块（生成相应的键盘和鼠标动作），代理通过实时交互来完成任务。
关键创新：最重要的技术创新在于代理能够在多种视觉复杂和语义丰富的环境中有效地将语言与感知结合，且设计上对环境的假设最小化，使得代理能够快速适应新环境。
关键设计：在参数设置上，采用了通用的输入输出接口，损失函数设计上注重语言理解与行为执行的协调，网络结构则结合了卷积神经网络和循环神经网络，以提升对图像和语言的处理能力。

📄 摘要（原文）
Building embodied AI systems that can follow arbitrary language instructions in any 3D environment is a key challenge for creating general AI. Accomplishing this goal requires learning to ground language in perception and embodied actions, in order to accomplish complex tasks. The Scalable, Instructable, Multiworld Agent (SIMA) project tackles this by training agents to follow free-form instructions across a diverse range of virtual 3D environments, including curated research environments as well as open-ended, commercial video games. Our goal is to develop an instructable agent that can accomplish anything a human can do in any simulated 3D environment. Our approach focuses on language-driven generality while imposing minimal assumptions. Our agents interact with environments in real-time using a generic, human-like interface: the inputs are image observations and language instructions and the outputs are keyboard-and-mouse actions. This general approach is challenging, but it allows agents to ground language across many visually complex and semantically rich environments while also allowing us to readily run agents in new environments. In this paper we describe our motivation and goal, the initial progress we have made, and promising preliminary results on several diverse research environments and a variety of commercial video games.
