Machine Collective Intelligence for Explainable Scientific Discovery

Researchers introduce machine collective intelligence, a paradigm combining symbolic reasoning and metaheuristics to autonomously discover governing equations from empirical data. The approach recovers underlying equations across deterministic, stochastic, and uncharacterized systems while reducing extrapolation error by up to six orders of magnitude compared to deep neural networks and condensing millions of parameters into just 5-40 interpretable ones.

LLM-ACES: Closed-Loop Discovery of Dynamical Systems with LLM-Guided Adaptive Search

Researchers introduce LLM-ACES, a framework combining large language models with active learning to discover governing equations of dynamical systems from data. The approach achieves significant improvements in accuracy and sample efficiency by using LLM-proposed hypotheses to guide strategic data acquisition, outperforming existing methods on 122 ODE systems while requiring substantially less training data.

naPINN: Noise-Adaptive Physics-Informed Neural Networks for Recovering Physics from Corrupted Measurement

Researchers introduce naPINN (Noise-Adaptive Physics-Informed Neural Networks), a novel machine learning approach that recovers accurate physical equations from corrupted or noisy measurement data without requiring prior knowledge of noise characteristics. The method uses energy-based models to identify and filter outliers while maintaining data integrity, substantially outperforming existing robust PINN methods across benchmark tests with non-Gaussian noise and varying outlier rates.

Discovering Ordinary Differential Equations with LLM-Based Qualitative and Quantitative Evaluation

Researchers introduce DoLQ, a new method that combines large language models with symbolic regression to discover ordinary differential equations from observational data. The approach integrates both qualitative physical reasoning and quantitative metrics through a multi-agent architecture, demonstrating superior performance over existing methods in recovering accurate symbolic equations.
