让智能体像人一样随时间逐步推理,突破现有模型的思维瓶颈。
Time-Scaling Is What Agents Need Now
- 通过延长推理时间路径,实现更深层的问题空间探索
- 在不增加参数量的前提下提升复杂任务解决能力
- 适合需要深度思考的AI系统设计与优化
早期人工智能范式分工明确:神经网络专注感知表征,强化学习负责决策行为,符号AI侧重知识推理。随着基于Transformer的大模型和世界模型的发展,这些范式正融合为具备闭环‘感知-决策-行动’能力的认知代理。人类在认知资源有限的情况下,通过时序化连续推理解决复杂问题,语言依赖问题空间搜索实现深层语义推理。尽管早期大语言模型能生成流畅文本,但缺乏稳健的语义推理能力。提示技术如思维链(CoT)和思维树(ToT)通过显式中间步骤扩展了推理路径,近期模型如DeepSeek-R1通过显式推理轨迹提升了性能。然而,这些方法在搜索完整性和效率上仍有局限。这凸显出‘时间缩放’(Time-Scaling)的必要性——即系统性地扩展与优化代理随时间展开推理的能力。时间缩放指通过架构设计利用扩展的时间路径,实现更深层次的问题空间探索、动态策略调整和增强的元认知控制,类比人类在认知约束下的序列推理。它代表了在不成比例增加静态模型参数的前提下,提升深度推理与解决问题能力的关键前沿。提升智能体能力需将时间缩放原则置于核心位置,将显式的时间推理管理作为基础。
原文摘要 · Abstract (English)
Early artificial intelligence paradigms exhibited separated cognitive functions: Neural Networks focused on "perception-representation," Reinforcement Learning on "decision-making-behavior," and Symbolic AI on "knowledge-reasoning." With Transformer-based large models and world models, these paradigms are converging into cognitive agents with closed-loop "perception-decision-action" capabilities. Humans solve complex problems under limited cognitive resources through temporalized sequential reasoning. Language relies on problem space search for deep semantic reasoning. While early large language models (LLMs) could generate fluent text, they lacked robust semantic reasoning capabilities. Prompting techniques like Chain-of-Thought (CoT) and Tree-of-Thought (ToT) extended reasoning paths by making intermediate steps explicit. Recent models like DeepSeek-R1 enhanced performance through explicit reasoning trajectories. However, these methods have limitations in search completeness and efficiency. This highlights the need for "Time-Scaling"--the systematic extension and optimization of an agent's ability to unfold reasoning over time. Time-Scaling refers to architectural design utilizing extended temporal pathways, enabling deeper problem space exploration, dynamic strategy adjustment, and enhanced metacognitive control, paralleling human sequential reasoning under cognitive constraints. It represents a critical frontier for enhancing deep reasoning and problem-solving without proportional increases in static model parameters. Advancing intelligent agent capabilities requires placing Time-Scaling principles at the forefront, positioning explicit temporal reasoning management as foundational.
