abstract
Q-learning is a fundamental algorithmic primitive in reinforcement learning. This paper develops a new framework for analyzing Q-learning from a switching linear system (SLS) viewpoint. In particular, we derive a stochastic SLS representation of the Q-learning error, and a finite-time error analysis through the joint spectral radius (JSR) of the corresponding SLS model, where the JSR is the exact worst-case exponential rate of the associated SLS. To the best of our knowledge, this is the first convergence rate analysis of standard Q-learning whose leading exponential rate is expressed through the JSR. The resulting rate is tied to the intrinsic worst-case exponential rate of the direct SLS representation and can be sharper than row-sum upper bounds when those bounds are conservative.

Periodic and soft target updates guarantee convergence in linear Q-learning to the exact projected Q-Bellman solution under spectral and step-size conditions via joint spectral radius analysis of switched linear systems.
Sign-separated analysis decomposes Q-learning errors into negative parts dominated by an optimal-policy LTI system and positive parts controlled by a switching system, yielding finite-time bounds for deterministic and stochastic cases.
Deflated Q-value iteration admits a projected switching-system model whose joint spectral radius can be strictly smaller than the discount factor, yielding a sharper convergence characterization while leaving the greedy policy sequence unchanged.
Derives an exact linear switched model for the mean dynamics of Q-learning with linear function approximation and relates convergence to joint spectral radius stability of the switched system, extending the view to stochastic and regularized cases.
Introduces and analyzes the λ-target update for linear Q-learning via geometric averaging of periodic target maps, studied with a switching-system model in the deterministic case.
