Mitigating Exploitation Bias in Learning to Rank with an Uncertainty-aware Empirical Bayes Approach
2024
Ranking is at the core of many artificial intelligence (AI) applications, including search engines, recommender systems, etc. Modern ranking systems are often constructed with learning-to-rank (LTR) models built from user behavior signals. While previous studies …

A Multi-Source Log Hidden Anomaly Detection Method Integrating Trans-Encoder and LSTM
2025 · IEEE Access
Identifying hidden anomalous behavior is a major challenge in anomaly detection, particularly in complex systems where anomalies are buried within massive log data and cannot be easily identified through simple patterns or rules. To address …
