Dataset Usage Inference without Shadow Models or Held-out Data

arXiv:2606.26257v1 Announce Type: new Abstract: How much of my data was used to train a machine learning model? Dataset Usage Inference (DUI) aims to answer this by estimating what fraction of a dataset contributed to a model's training. However, existing DUI methods rely on assumptions that rarely hold in practice: they require training expensive shadow models to imitate the target model, and they assume access to both known training samples and an in-distribution held-out set confirmed to be absent from training. These conditions make current approaches impractical for modern large models an

Why this matters
Why now

The proliferation of advanced AI models necessitates improved methods for understanding data lineage and usage, especially in light of increasing regulatory and ethical concerns.

Why it’s important

This research addresses a critical gap in AI model auditing and transparency, enabling better compliance, intellectual property protection, and trust in AI systems.

What changes

New methodologies for Dataset Usage Inference (DUI) will allow more practical and scalable assessment of how data contributes to large machine learning models, without the prohibitive costs of prior methods.

Winners
  • · AI developers
  • · Data owners
  • · Regulatory bodies
  • · Ethical AI advocates
Losers
  • · Developers of less transparent models
  • · Systems reliant on proprietary 'black box' data usage
Second-order effects
Direct

Easier and more accurate assessment of data contributions to large AI models, improving transparency.

Second

Increased accountability for AI model training data, potentially impacting intellectual property and privacy regulations.

Third

The development of 'data footprint' audits becoming a standard requirement for AI model deployment and certification.
