FLAG n' FLARE: Fast Linearly-Coupled Adaptive Gradient Methods

Xiang Cheng, Farbod Roosta-Khorasani, Stefan Palombo +2

We consider first order gradient methods for effectively optimizing a composite objective in the form of a sum of smooth and, potentially, non-smooth functions. We present accelera…

Asymptotic behavior of $ℓ_{p}$ -based Laplacian regularization in semi-supervised learning

Ahmed El Alaoui, Xiang Cheng, Aaditya Ramdas +2

Given a weighted graph with $N$ vertices, consider a real-valued regression problem in a semi-supervised setting, where one observes $n$ labeled vertices, and the task is to label…
