To continuously improve quality and reflect changes in data, machine learning applications have to regularly retrain and update their core models.<\/p>\n
We show that a differential analysis of language model snapshots before and after an update can reveal a surprising amount of detailed information about changes in the training data.<\/p>\n
We propose two new metrics—differential score<\/em> and differential rank<\/em>—for analyzing the leakage due to updates of natural language models. We perform leakage analysis using these metrics across models trained on several different datasets using different methods and configurations.<\/p>\n We discuss the privacy implications of our findings, propose mitigation strategies and evaluate their effect.<\/p>\n","protected":false},"excerpt":{"rendered":" To continuously improve quality and reflect changes in data, machine learning applications have to regularly retrain and update their core models.
