从植物行为中汲取灵感,构建新型AI问题框架。
Plant-Inspired AI: Plants as Inspiration for Novel Problem Formulations, and Two Case Studies

- 借鉴植物适应环境的智能行为,提出新计算范式。
- 发现叶形模仿与根茎协调生长两类未被现有AI覆盖的问题。
- 适合对生物启发算法、跨系统协同优化感兴趣的学者。
人工智能长期受生物智能研究启发,如强化学习源自动物学习研究,并已成为解决诸多现实问题的强大范式。近期植物生物学揭示了植物在多变环境中灵活适应的复杂行为。本文认为,这些行为可激发新的AI框架,涵盖现有方法如监督学习、树搜索和约束满足所忽略的问题。以两种植物智能行为为例:(1) Boquila trifoliolata藤本植物能同时模仿多种寄主树木的叶形;(2) 多数植物通过协调根茎系统资源分配,在不同环境区域探索。尽管叶形模仿具有物种特异性,但根茎协调生长普遍存在。我们提炼其背后计算原理,识别出当前未被AI解决的新问题,并初步提出任务建模,探讨其在非植物场景中的应用潜力。
原文摘要 · Abstract (English)
Artificial Intelligence (AI) has long been inspired by studies of biological intelligence. Reinforcement learning, for instance, drew inspiration from studies involving animal learning and is now a powerful paradigm for solving many real-world problems. Recently, plant biologists have uncovered a wide range of complex behaviors in plants that enable them to flexibly adapt to variable environments. Here, we argue that such behavior can motivate new AI frameworks encompassing a range of problems overlooked by existing problem-solving frameworks such as supervised learning, tree search, and constraint satisfaction. We illustrate this idea with two examples of intelligent problem-solving in plants: (1) leaf mimicry in Boquila trifoliolata, a vine capable of altering its leaves' morphology to resemble those of multiple host trees simultaneously; and (2) coordinated root-shoot growth, wherein plants allocate resources across organ systems exploring distinct environments. While leaf mimicry is highly specific to Boquila, coordination of root-shoot growth is shared across most plants. For both examples, we capture underlying computational principles and identify problems fitting these frameworks that are currently unaddressed by AI. Finally, we outline preliminary task formulations and discuss how these formulations may be applied to non-plant problems.
