A new research paper introduces a benchmark for data quality profiling in large-scale AI pipelines, evaluating nine different sampling strategies. The study found that simple, schema-free random uniform sampling performed best, achieving the lowest mean relative error on various real-world and synthetic datasets. In contrast, more complex proxy-guided methods, such as those using Metropolis-Hastings or directed acyclic graphs, were significantly less effective and computationally more expensive, especially at scale.
