Skip-Sliding Window Codes

2017 · arXiv (Cornell University)

Constrained coding is used widely in digital communication and storage systems. In this paper, we study a generalized sliding window constraint called the skip-sliding window. A skip-sliding window (SSW) code is defined in terms of …

SGA: A Robust Algorithm for Partial Recovery of Tree-Structured\n Graphical Models with Noisy Samples

2021 · arXiv (Cornell University)

We consider learning Ising tree models when the observations from the nodes\nare corrupted by independent but non-identically distributed noise with unknown\nstatistics. Katiyar et al. (2020) showed that although the exact tree structure\ncannot be recovered, one …

Mean Estimation with User-Level Privacy for Spatio-Temporal IoT Datasets

2024

This paper considers the problem of the private release of sample means of speed values from traffic datasets. Our key contribution is the development of user-level differentially private algorithms that incorporate carefully chosen parameter values …
