用好奇心驱动的AI在流型细胞自动机中发现多样生态动态
Exploring Flow-Lenia Universes with a Curiosity-driven AI Scientist: Discovering Diverse Ecosystem Dynamics
- 用内在动机探索过程寻找复杂系统中的自组织模式
- 比随机搜索覆盖更广的动态空间,发现类生物行为
- 适合研究复杂系统自下而上集体行为的学者
我们提出一种好奇心驱动的AI科学家方法,用于探索具有质量守恒和参数局部化的连续细胞自动机Flow-Lenia中的系统级动态。在先前工作基础上,将内在动机目标探索过程(IMGEP)扩展至大尺度相互作用模式环境,使用演化活跃度、压缩比和多尺度物质分布等全局指标。在两项实验中——生态系统级动态与障碍物环境中物质运动——IMGEP显著拓展了度量空间的覆盖范围,并揭示出定性类似多种生物现象的自组织行为。基于生成的档案,我们进行了跨六种空间尺度和七种时间跨度的缩放研究,发现宏观尺度存在基础尺度无对应结构,并刻画了目标空间度量在不同尺度下的表现。该方法优势在于:低成本的大规模多样性搜索可作为后续高成本实验的结构化基础,支持实验设计、检视与重设计的迭代循环,且配有交互式探索工具让研究人员持续参与。尽管以Flow-Lenia为例,该方法可推广至其他可参数化复杂系统中对自下而上集体行为的研究。
原文摘要 · Abstract (English)
We present a curiosity-driven AI scientist method for discovering system-level dynamics in Flow-Lenia, a continuous cellular automaton (CA) with mass conservation and parameter localization. Building on prior work that uses diversity search in Lenia to find individual self-organized patterns, we adapt Intrinsically Motivated Goal Exploration Processes (IMGEPs) to large environments of interacting patterns, using simulation-wide metrics such as evolutionary activity, compression ratio, and multi-scale matter distribution. We apply IMGEP in two exploration experiments: one targeting ecosystem-level dynamics, the other matter movement through obstacle-laden environments. In both, IMGEP illuminates significantly more of the metric space than random search and reveals self-organized behaviors qualitatively resembling many biological phenomena. Leveraging the resulting archive, we then run a scaling study across six spatial scales and seven time horizons, uncovering macro-scale organization with no analogue at the base scale and characterizing how goal-space metrics behave at scale. This illustrates a strength of our approach: a relatively cheap large-scale diversity search can act as a principled scaffold for designing subsequent, more expensive experiments, enabling an iterative loop of experiment design, inspection, and redesign, supported by an interactive exploration tool that keeps scientists in the loop. Though demonstrated with Flow-Lenia, this approach potentially applies to other parameterizable complex systems where studying bottom-up collective behavior is of interest.
