摘要:

几十年来,人工智能(AI)在科学活动中的应用越来越多;然而,在科学过程中,它仍然远远不是一个有洞察力和值得信赖的合作者。大多数现有的人工智能方法要么过于简单,无法解决科学家面临的实际问题,要么过于专业化(甚至教条化),扼杀了变革性的发现或范式转变。我们提出了一个早期科学发现的人工智能研究助理,基于(a)一个新的基于物理的建模的最小偏差本体,它是上下文感知的,可解释的,并且可以在经典和相对论物理学中推广;(b)自动搜索可行和简约的假设,在高级别(通过域不可知结构)表示,具有内置的不变量,例如,由预先假定的时空拓扑隐含的守恒原理的假定形式;以及(c)将所列举的假设自动编译为领域特定的、可解释的和可训练/可测试的基于张量的计算图以学习现象学关系,例如,本构或材料的法律,从稀疏(和可能的噪音)的数据集。

英文摘要:

Artificial intelligence (AI) has been increasingly applied in scientific activities for decades; however, it is still far from an insightful and trustworthy collaborator in the scientific process. Most existing AI methods are either too simplistic to be useful in real problems faced by scientists or too domain-specialized (even dogmatized), stifling transformative discoveries or paradigm shifts. We present an AI research associate for early-stage scientific discovery based on (a) a novel minimally-biased ontology for physics-based modeling that is context-aware, interpretable, and generalizable across classical and relativistic physics; (b) automatic search for viable and parsimonious hypotheses, represented at a high-level (via domain-agnostic constructs) with built-in invariants, e.g., postulated forms of conservation principles implied by a presupposed spacetime topology; and (c) automatic compilation of the enumerated hypotheses to domain-specific, interpretable, and trainable/testable tensor-based computation graphs to learn phenomenological relations, e.g., constitutive or material laws, from sparse (and possibly noisy) data sets.
