多模态AI系统将成为我们日常生活中的普遍存在。通过将这些系统具象化为物理和虚拟环境中的代理,能够提升其互动性。当前,系统利用现有的基础模型作为构建具象代理的基本模块。将代理嵌入环境中,有助于模型处理和解释视觉及上下文数据,这对于创建更复杂和具有上下文感知能力的AI系统至关重要。我们定义“Agent AI”为一种能够感知视觉刺激、语言输入及其他环境数据的交互系统,并能够产生有意义的具象行为。我们探讨了通过引入外部知识、多感官输入和人类反馈来改善基于下一步具象行为预测的代理系统。
🔬 方法详解
问题定义:论文旨在解决现有多模态AI系统在环境感知和用户互动中的不足,特别是缺乏上下文理解和行为生成的能力。现有方法往往依赖于单一模态,导致输出的环境信息不准确。
核心思路:论文提出的核心思路是将代理嵌入物理和虚拟环境中,利用多模态输入(如视觉、语言和音频)和外部知识来提升代理的互动能力和上下文理解。通过这种方式,代理能够更好地理解用户行为和环境状态,从而生成更合适的响应。
技术框架:整体架构包括三个主要模块:环境感知模块、行为生成模块和反馈学习模块。环境感知模块负责处理多模态输入,行为生成模块根据感知信息生成具象行为,反馈学习模块则通过人类反馈不断优化代理的表现。
关键创新:最重要的技术创新在于引入了多模态输入和外部知识的结合,显著提升了代理的环境感知能力和行为生成的准确性。这一方法与传统的单一模态方法形成鲜明对比,能够有效减少生成错误输出的情况。
关键设计:在技术细节上,论文采用了多层次的神经网络结构,结合了不同模态的特征提取,并设计了适应性损失函数以平衡各模态的影响。此外,反馈学习模块通过强化学习机制不断调整代理的行为策略。

📄 摘要(原文)
Multi-modal AI systems will likely become a ubiquitous presence in our everyday lives. A promising approach to making these systems more interactive is to embody them as agents within physical and virtual environments. At present, systems leverage existing foundation models as the basic building blocks for the creation of embodied agents. Embedding agents within such environments facilitates the ability of models to process and interpret visual and contextual data, which is critical for the creation of more sophisticated and context-aware AI systems. For example, a system that can perceive user actions, human behavior, environmental objects, audio expressions, and the collective sentiment of a scene can be used to inform and direct agent responses within the given environment. To accelerate research on agent-based multimodal intelligence, we define "Agent AI" as a class of interactive systems that can perceive visual stimuli, language inputs, and other environmentally-grounded data, and can produce meaningful embodied actions. In particular, we explore systems that aim to improve agents based on next-embodied action prediction by incorporating external knowledge, multi-sensory inputs, and human feedback. We argue that by developing agentic AI systems in grounded environments, one can also mitigate the hallucinations of large foundation models and their tendency to generate environmentally incorrect outputs. The emerging field of Agent AI subsumes the broader embodied and agentic aspects of multimodal interactions. Beyond agents acting and interacting in the physical world, we envision a future where people can easily create any virtual reality or simulated scene and interact with agents embodied within the virtual environment.
