Boosting uniformity in quasirandom groups: fast and simple

Harm Derksen, Chin Ho Lee, Emanuele Viola

We study the communication complexity of multiplying elements from the group in the number-on-forehead model with parties. We prove a lower bound…

Pseudorandomness, symmetry, smoothing: II

Harm Derksen, Peter Ivanov, Chin Ho Lee +1

We prove several new results on the Hamming weight of bounded uniform and small-bias distributions. We exhibit bounded-uniform distributions whose weight is anti-concentrated, matc…

Trace reconstruction from local statistical queries

Xi Chen, Anindya De, Chin Ho Lee +1

The goal of trace reconstruction is to reconstruct an unknown -bit string given only independent random traces of , where a random trace of is obtained by passing …

Pseudorandomness, symmetry, smoothing: I

Harm Derksen, Peter Ivanov, Chin Ho Lee +1

We prove several new results about bounded uniform and small-bias distributions. A main message is that, small-bias, even perturbed with noise, does not fool several classes of tes…

Approximate Trace Reconstruction from a Single Trace

Xi Chen, Anindya De, Chin Ho Lee +2

The well-known trace reconstruction problem is the problem of inferring an unknown source string from independent "traces", i.e. copies of that have been corr…

Near-Optimal Average-Case Approximate Trace Reconstruction from Few Traces

Xi Chen, Anindya De, Chin Ho Lee +2

In the standard trace reconstruction problem, the goal is to \emph{exactly} reconstruct an unknown source string from independent "traces", which are cop…

Fourier growth of structured -polynomials and applications

Jarosław Błasiok, Peter Ivanov, Yaonan Jin +3

We analyze the Fourier growth, i.e. the Fourier weight at level (denoted ), of various well-studied classes of "structured" -polynomials. This stud…

Polynomial-time trace reconstruction in the low deletion rate regime

Xi Chen, Anindya De, Chin Ho Lee +2

In the \emph{trace reconstruction problem}, an unknown source string is transmitted through a probabilistic \emph{deletion channel} which independently deletes ea…

Polynomial-time trace reconstruction in the smoothed complexity model

Xi Chen, Anindya De, Chin Ho Lee +2

In the \emph{trace reconstruction problem}, an unknown source string is sent through a probabilistic \emph{deletion channel} which independently deletes each bit…

Fractional Pseudorandom Generators from Any Fourier Level

Eshan Chattopadhyay, Jason Gaitonde, Chin Ho Lee +2

We prove new results on the polarizing random walk framework introduced in recent works of Chattopadhyay {et al.} [CHHL19,CHLT19] that exploit Fourier tail bounds for classes…

Fourier bounds and pseudorandom generators for product tests

Chin Ho Lee

We study the Fourier spectrum of functions which can be written as a product of Boolean functions on disjoint -bit inputs. We pro…

Homomorphic encryption from codes

Andrej Bogdanov, Chin Ho Lee

We propose a new homomorphic encryption scheme based on the hardness of decoding under independent random noise from certain affine families of codes. Unlike in previous lattice-ba…
