Researchers have introduced LakeMLB, the first benchmark specifically designed for multi-table machine learning within data lake environments. This benchmark addresses the scarcity of standardized evaluations for ML performance in data lakes, which are crucial for managing large-scale, heterogeneous data. LakeMLB encompasses two primary scenarios, Union and Join, utilizing six real-world datasets and supporting three multi-table learning paradigms: pre-training, data augmentation, and feature augmentation, complete with standardized data splits and evaluation protocols. The project aims to foster rigorous research by releasing both the datasets and associated code. AI
