Locally Correctable Lattices

ICASSP 2025accepted

Point lattices play an important role in various fields of computer science, including communication, cryptography, optimization, and machine learning. In this work, we introduce the concept of Locally Correctable Lattices (LCLs)—a class of lattices with an efficient reconstruction algorithm that ca…

Support Recovery in 1-Bit Compressed Sensing with Burst Sparse Noise

ICASSP 2025accepted

1-bit compressed sensing (1bCS) is a quantized signal acquisition technique to compress high-dimensional sparse signals. The goal is to design sensing matrices A ∈ ℝ<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m×n</sup> with the fewest possible rows…

Support Recovery of Sparse Signals from a Mixture of Linear Measurements

NeurIPS 2021poster

Recovery of support of a sparse vector from simple measurements is a widely studied problem, considered under the frameworks of compressed sensing, 1-bit compressed sensing, and more general single index models. We consider generalizations of this problem: mixtures of linear regressions, and mixture…

vqSGD: Vector Quantized Stochastic Gradient Descent

AISTATS 2021poster

In this work, we present a family of vector quantization schemes vqSGD (Vector-Quantized Stochastic Gradient Descent) that provide an asymptotic reduction in the communication cost with convergence guarantees in first-order distributed optimization. In the process we derive the following fundamental…

Recovery of sparse linear classifiers from mixture of responses

NeurIPS 2020poster

In the problem of learning a mixture of linear classifiers, the aim is to learn a collection of hyperplanes from a sequence of binary responses. Each response is a result of querying with a vector and indicates the side of a randomly chosen hyperplane from the collection the query vector belong to.…

Superset Technique for Approximate Recovery in One-Bit Compressed Sensing

NeurIPS 2019poster

One-bit compressed sensing (1bCS) is a method of signal acquisition under extreme measurement quantization that gives important insights on the limits of signal compression and analog-to-digital conversion. The setting is also equivalent to the problem of learning a sparse hyperplane-classifier. In…
