Least Squares Approximation via Sparse Subsampled Randomized Hadamard Transform
IEEE Transactions on Big Data, 2022Solving least squares (LS) problems is a major topic in many applications. With recent data explosion, traditional approach is no longer suitable while working with large datasets, instead, randomized algorithms become popular in addressing this issue ...

Design and implementation of the Walsh-Hadamard transform on a ternary optical computer.
Applied Optics, 2021Walsh-Hadamard is a commonly used mathematical transformation, a mathematical method for spectrum analysis in the real number domain, which has been widely used in many fields such as digital signal processing, spectral modulation, and image processing ...

In many fields (e.g., spectroscopy, imaging spectroscopy, photoacoustic imaging, coded aperture imaging) binary bit patterns known as m sequences are used to encode (by multiplexing) a series of measurements in order to obtain a larger throughput. The observed measurements must be decoded to obtain the desired spectrum (or image in the case of coded ...

HPLC-Detector Based on Hadamard-Transform Fluorescence Excitation-Emission-Matrix Spectroscopy.
Analytical Chemistry, 2021We present a new rapid-acquisition HPLC detector based on a Hadamard-transform (HT) excitation-emission-matrix (EEM) fluorescence spectrometer allowing the acquisition of two-dimensional spectra at a rate faster than 6 spectra per second (

Hadamard Transform Capillary Electrophoresis
Analytical Chemistry, 1999This paper reports the first demonstration of a multiplex sample injection technique in capillary electrophoresis. The sample was injected into a capillary (effective length, 4 cm) as a pseudorandam Hadamard sequence by a photodegradation technique using a high-power gating laser, and the fluorescence signal, which was measured using a probe excitation
