From Random to Explicit via Subspace Designs With Applications to Local Properties and Matroids
Joshua Brakensiek, Yeyuan Chen, Manik Dhar +1
In coding theory, a common question is to understand the threshold rates of various local properties of codes, such as their list decodability and list recoverability. A recent wor…
Combinatorial Bounds for List Recovery via Discrete Brascamp--Lieb Inequalities
Joshua Brakensiek, Yeyuan Chen, Manik Dhar +1
In coding theory, the problem of list recovery asks one to find all codewords of a given code which such that at least fraction of the symbols of lie in some pred…
Optimal Erasure Codes and Codes on Graphs
Yeyuan Chen, Mahdi Cheraghchi, Nikhil Shagrithaya
We construct constant-sized ensembles of linear error-correcting codes over any fixed alphabet that can correct a given fraction of adversarial erasures at rates approaching the Si…
Unique Decoding of Reed-Solomon and Related Codes for Semi-Adversarial Errors
Joshua Brakensiek, Yeyuan Chen, Manik Dhar +1
Motivated by recent developments in coding theory, particular in list-decoding, we introduce a new error model which we call semi-adversarial errors. This error model bridges betwe…
