Quasipolynomial Trace Reconstruction

Arnav Burudgunte, Paul Valiant, Hongao Wang

We show that trace reconstruction on n-bit strings is possible using a quasipolynomial number of traces, for any retention probability p that is at least inverse polylogarithmic in…

The Median is Easier than it Looks: Approximation with a Constant-Depth, Linear-Width ReLU Network

Abhigyan Dutta, Itay Safran, Paul Valiant

We study the approximation of the median of inputs using ReLU neural networks. We present depth-width tradeoffs under several settings, culminating in a constant-depth, linear-…

New Bounds for Circular Trace Reconstruction

Arnav Burudgunte, Paul Valiant, Hongao Wang

The ''trace reconstruction'' problem asks, given an unknown binary string and a channel that repeatedly returns ''traces'' of with each bit randomly deleted with some proba…

A Generalized Trace Reconstruction Problem: Recovering a String of Probabilities

Joey Rivkin, Gregory Valiant, Paul Valiant

We introduce the following natural generalization of trace reconstruction, parameterized by a deletion probability and length : There is a length string of prob…

Depth Separations in Neural Networks: Separating the Dimension from the Accuracy

Itay Safran, Daniel Reichman, Paul Valiant

We prove an exponential size separation between depth 2 and depth 3 neural networks (with real inputs), when approximating a -Lipschitz target function to constant…

Optimality in Mean Estimation: Beyond Worst-Case, Beyond Sub-Gaussian, and Beyond Moments

Trung Dang, Jasper C. H. Lee, Maoyuan Song +1

There is growing interest in improving our algorithmic understanding of fundamental statistical problems such as mean estimation, driven by the goal of understanding the limits of…
