INTERACT: Achieving Low Sample and Communication Complexities in Decentralized Bilevel Learning over Networks

no code implementations27 Jul 2022 Zhuqing Liu, Xin Zhang, Prashant Khanduri, Songtao Lu, Jia Liu

Our main contributions in this paper are two-fold: i) We first propose a deterministic algorithm called INTERACT (inner-gradient-descent-outer-tracked-gradient) that requires the sample complexity of $\mathcal{O}(n \epsilon^{-1})$ and communication complexity of $\mathcal{O}(\epsilon^{-1})$ to solve the bilevel optimization problem, where $n$ and $\epsilon > 0$ are the number of samples at each agent and the desired stationarity gap, respectively.
