Crypto-Mine: Cryptanalysis Via Mutual Information Neural Estimation

ICASSP 2024accepted

The use of Mutual Information (MI) as a measure to evaluate the efficiency of cryptosystems has an extensive history. However, estimating MI between unknown random variables in a high-dimensional space is challenging. Recent advances in machine learning have enabled progress in estimating MI using n…

Multi-Level Group Testing with Application to One-Shot Pooled COVID-19 Tests

ICASSP 2021accepted

One of the main challenges in containing the Coronoavirus disease 2019 (COVID-19) pandemic stems from the difficulty in carrying out efficient mass diagnosis over large populations. The leading method to test for COVID-19 infection utilizes qualitative polymerase chain reaction, implemented using de…

Distributed Quantization for Sparse Time Sequences

ICASSP 2020accepted

Analog signals processed in digital hardware are quantized into a discrete bit-constrained representation. Quantization is typically carried out using analog-to-digital converters (ADCs), operating in a serial scalar manner. In some applications, a set of analog signals are acquired individually and…

Combined Weighted Prediction Error and Minimum Variance Distortionless Response for dereverberation

ICASSP 2017accepted

Considering the dereverberation problem using multichannel processing, two main paradigms exist. The first paradigm utilizes the long-term correlation of the reverberant component for reducing it, e.g. Weighted Prediction Error (WPE) [1]. The second paradigm, treats the reverberation as a diffuse no…
