Adaptive Graph-of-Islands Evolution for Automatic Feature Engineering with LLMs

T TOPOFE is introduced, a framework that formulates AutoFE as graph-structured multi-island evolutionary program search that produces feature sets with lower redundancy and higher representational coverage, while the learned topology graph acquires meaningful task-specific transfer structure correlated with downstream...

TopoFE: topology-aware LLM-guided Automated Feature Engineering

Automatic feature engineering (AutoFE) for tabular learning can be naturally formulated as a program synthesis problem, where the objective is to discover predictive feature transformations from an exponentially large search space. Recent advances in large language models (LLMs) have expanded the expressiveness of Auto...
