A new paper explores the concept of "benchmark hacking" in machine learning contests, where participants optimize models for specific evaluation metrics rather than true generalization. The research models this phenomenon as a game theory problem, identifying conditions under which contestants will engage in such hacking. It suggests that skewed reward structures, favoring top performers, can lead to more desirable contest outcomes and provides empirical evidence for these theoretical predictions. AI
