New framework analyzes policy learning problems with limited data · 2 sources tracked

Researchers have introduced a new mathematical framework to analyze the relationships between different policy learning problems, particularly when data is insufficient for traditional methods. The framework formalizes three problems: finding the optimal policy, learning an improving policy that outperforms baselines, and determining if an improving policy even exists. The study demonstrates that the policy existence problem can be reduced to the improving policy problem, which in turn reduces to the optimal policy problem, indicating a hierarchy of difficulty. The research also suggests that a gap exists between finding an improving policy and merely determining its existence, potentially allowing for answers even with limited data. AI
