Researchers have developed a novel online statistical inference framework for nonlinear stochastic approximation algorithms that utilize Markovian data. This framework establishes a functional central limit theorem for partial-sum paths, enabling the creation of self-normalized confidence intervals without the need for asymptotic variance estimation. The proposed method, which employs a five-dimensional polynomial-series normalizer, demonstrates near-nominal coverage and offers reduced computational costs compared to online bootstrap methods. Its applications include Q-learning, generalized linear models with Markov data, and inference for low-rank adaptation (LoRA). AI
