An Agentic AI Scientific Community for Automated Neural Operator Discovery

Summary

An agentic AI scientific community is introduced for automated neural operator discovery, comprising a swarm of virtual laboratories operating under a citation-based influence economy. Each lab features an LLM planner for architecture proposals, a numerical worker for training and measurement, and an LLM reviewer for peer review. These labs share a common vocabulary of building blocks like DeepONet, Fourier, and Transformer. Evaluated on five problems, including piecewise regression and various 1D and 2D PDEs (e.g., Navier-Stokes), the system successfully discovers high-accuracy, low-parameter-count neural operator architectures. Audited logs of 9,623 LLM calls reveal that LLM planners consistently hybridize in 99.8% of decisions, producing multi-family hybrids. An ablation study confirmed LLM agency is crucial for maintaining architectural diversity, as rule-based alternatives led to a collapse into non-hybridized single-family stacks. The findings suggest a "no-free-lunch" theorem for neural operators, indicating no single universal winner.

Key takeaway

For Machine Learning Engineers developing neural operators, you should prioritize exploring hybrid architectures rather than seeking a single optimal solution. The "no-free-lunch" finding implies tailoring specific multi-family hybrids to your problem domain will likely yield better results. Integrate LLM-powered agents into your architecture search workflows to foster diversity and accelerate discovery of high-performing, low-parameter models.
