Active Regression for Single-Index Models with Unknown Link Functions

Chansophea Wathanak In, Yi Li, Wai Ming Tai +1

This paper studies active regression for single-index models under general $ℓ_{p}$ -loss with an unknown $1$ -Lipschitz link function $f$ , formulated as $min_{f, x} ∥ f (A x) - b ∥_{p}^{p}$ …

Near-optimal Active Regression of Single-Index Models

Yi Li, Wai Ming Tai

The active regression problem of the single-index model is to solve $min_{x} ∥ f (A x) - b ∥_{p}$ , where $A$ is fully accessible and $b$ can only be accessed via entry queries, w…
