New technique analyzes Q-learning convergence and bias in stochastic approximation
Researchers have developed a new technique for analyzing nonsmooth contractive stochastic approximation (SA) dynamics, particularly relevant to Q-learning. The study establishes weak convergence of iterates to a station…

Research paper explores nonstationarity's impact on regret minimization in bandits
Researchers have investigated satisficing regret minimization in nonstationary K-armed bandits, finding that even minor deviations from stationarity significantly increase regret. The study demonstrates that in piecewis…
