An efficient quantum algorithm for ensemble classification using bagging

IET Quantum Communication, Volume 5, Issue 3, Page 253-268, September 2024.
A new quantum algorithm that exploits quantum superposition, entanglement, and interference to build an ensemble of classification models is introduced. Thanks to the generation of several quantum trajectories in superposition, the authors obtain an exponentially large number of base models increasing only linearly the depth of the correspondent ...

FPGA‐based parallel process for Walsh–Hadamard transform

Electronics Letters, 2020
A field‐programmable gate array‐based reconfigurable parallel computing unit to calculate the Walsh–Hadamard transform is proposed. The architecture can process long‐duration signals with a large number of samples. Obtained results demonstrate its versatility and usefulness in applications requiring online digital signal processing, utilising few ...

Generalized bent Boolean functions and strongly regular Cayley graphs [PDF]

, 2017
In this paper we define the (edge-weighted) Cayley graph associated to a generalized Boolean function, introduce a notion of strong regularity and give several of its properties.

Walsh - Hadamard Transformation of a Convolution

Radioengineering, 2002
A convolution is mathematical operation used in signal processing,in the homomorphous signal processing and digital image processing(e.g. image interpolation). In regard of computational complexity ofthe convolution in the time domain, it used to calculate in the otherdomain. Exp. x(n) * h(n) R X(W) × H(W), resp.

A NEW DISCRETE HARTLEY TRANSFORM PRECODING BASED INTERLEAVED-OFDMA UPLINK SYSTEM WITH REDUCED PAPR FOR 4G CELLULAR NETWORKS [PDF]

Journal of Engineering Science and Technology, 2011
High peak-to-average power ratio (PAPR) reduction is one of the major challenges in orthogonal frequency division multiple access (OFDMA) systems since last decades. High PAPR increases the complexity of analogue-to-digital (A/D) and digital-to-analogue (

Efficient Quantum Transforms

, 1997
Quantum mechanics requires the operation of quantum computers to be unitary, and thus makes it important to have general techniques for developing fast quantum algorithms for computing unitary transforms.
