THE AI ANGLE
Reviewing data pipelines to detect data leakage

Researchers planted four common data leakage flaws into real machine learning projects and asked four AI models to evaluate the setups. Every model detected the primary leak from pipeline descriptions or code snippets without hints. Data practitioners can use language models as an early review tool to catch flawed validation designs before training.

THE TEACHING ANGLE
Simpler AI models caught primary leaks but missed secondary temporal split errors, whereas larger models identified both problems and critiqued the underlying metrics.
