Core Concepts
Explainable AI is effective in identifying and mitigating prediction anomalies caused by feature corruption in machine learning models.
Abstract
The paper introduces the application of Explainable AI (XAI) to address performance degradation in machine learning models.
Feature corruption can lead to prediction anomalies, impacting model reliability in systems like personalized advertising.
Techniques like temporal shifts in global feature importance distribution help isolate the cause of prediction anomalies.
The methodology involves estimating local feature importances, aggregating them to obtain global feature importances, and ranking features to identify the root cause of anomalies.
Results show the effectiveness of XAI in identifying various types of feature corruptions compared to model-feature correlation approaches.
Continuous monitoring using XAI aids in proactive anomaly detection and root cause analysis.
