Searching the Space of Feed-Forward Neural-Network Weight-Update Rules with Fixed Depth Symbolic Regression

arXiv cs.LG · 2026-07-27 Cached

This paper investigates using symbolic regression to discover explicit neural network weight-update rules that outperform standard hand-designed optimizers on small symbolic regression benchmarks, achieving an aggregate MSE reduction of 44.47% in 25 out of 30 benchmark/network combinations.

OPTScientist: Multi-Agent Discovery of Typed Optimizer Programs for Transformer Pretraining

arXiv cs.AI · 2026-07-24 Cached

This paper introduces OPTScientist, a theory-guided multi-agent framework for automatically discovering typed optimizer programs using a domain-specific language and closed-loop experimentation. The framework discovered RS-MR, a reduced-state matrix optimizer that improves transformer pretraining over strong baselines.
