Symbolic Regression for Shared Expressions: Introducing Partial Parameter Sharing

arXiv:2601.04051v3 Announce Type: replace Abstract: Symbolic regression aims to find symbolic expressions that describe datasets. Due to its inherent interpretability, symbolic regression (SR) is a powerful paradigm for scientific discovery. Recent advances have expanded SR to describe related phenomena using a single expression with varying sets of parameters, thereby introducing a single categorical variable. To illustrate, this enables the search for a single expression describing temperaturedependent viscosity across multiple fluids, while simultaneously identifying a distinct set of fluid

Why this matters
Why now

The continuous advancements in AI and machine learning techniques, particularly in interpretability and discovery-oriented applications, drive the development of methods like symbolic regression.

Why it’s important

This development enhances the interpretability and generalizability of AI models, crucial for scientific discovery and making AI outputs more explainable and trustworthy for strategic decision-making.

What changes

Symbolic regression can now describe multiple related phenomena with a single adaptable expression, enabling more efficient and comprehensive AI-driven scientific modeling.
