Heng Xu was appointed by the Association for Computing Machinery (ACM) Publications Board to a three-year term (May 15, 2024 - May 14, 2027) as the Editor-in-Chief for the ACM Transactions on Management Information Systems....
Language models alter their behavior when they infer that they are being trained, evaluated, deployed, or weakly overseen. Recent AI safety work treats this as evidence of scheming, and substantial...
Autoregressive reasoning traces often sharpen as they unfold — entropy falls and token probabilities concentrate — suggesting decoding is resolving uncertainty. Yet the same pattern persists after clear reasoning errors....
Machine learning has long held intuitive appeal in aiding theory building, owing to its capacity to automatically uncover intricate patterns from vast amounts of observed data. Yet, recent literature in...

“Reducing Subgroup Differences in Personnel Selection through the Application of Machine Learning”, a paper co-authored by Nan Zhang, Heng Xu, and 11 other co-authors, received the 2025 Best Paper Award...
Two potential obstacles stand between the observation of a statistical correlation and the design (and deployment) of an effective intervention, omitted variable bias and reverse causality. Whereas the former has...
