Estimation of Monotone Multi-Index Models

David Gamarnik, Julia Gaudio

In a multi-index model with $k$ index vectors, the input variables are transformed by taking inner products with the index vectors. A transfer function $f: \mathbb{R}^k \to \mathbb…

An Improved Lower Bound for the Traveling Salesman Constant

Julia Gaudio, Patrick Jaillet

Let $X_{1}, X_{2}, \dots, X_{n}$ be independent uniform random variables on $[0, 1]^{2}$ . Let $L (X_{1}, \dots, X_{n})$ be the length of the shortest Traveling Salesman tour through these points…

Sparse High-Dimensional Isotonic Regression

David Gamarnik, Julia Gaudio

We consider the problem of estimating an unknown coordinate-wise monotone function given noisy measurements, known as the isotonic regression problem. Often, only a small subset of…

Attracting Random Walks

Julia Gaudio, Yury Polyanskiy

This paper introduces the Attracting Random Walks model, which describes the dynamics of a system of particles on a graph with $n$ vertices. At each step, a single particle moves t…
