An approach to adaptive filtering with variable step size based on geometric algebra
IET Communications, 2022 Recently, adaptive filtering algorithms have attracted much more attention in the field of signal processing. By studying the shortcoming of the traditional real‐valued fixed step size adaptive filtering algorithm, this paper proposed the novel approach ...

A multi‐channel geometric algebra residual network for traffic data prediction
IET Intelligent Transport Systems, 2022 Traffic data prediction offers a significant way to evaluate the future traffic congestion status; many deep learning based approaches have been widely applied in this field. Most current methods only consider short‐term traffic data forecasting; however,

Dynamic and Geometric Phase Formulasin the Hestenes-Dirac Theory [PDF]
, 2003 We examine the dynamic and geometric phases of the electron in quantum mechanics using Hestenes' spacetime algebra formalism. First the standard dynamic phase formula is translated into the spacetime algebra.

Geometric-algebra affine projection adaptive filter
EURASIP Journal on Advances in Signal Processing, 2021 Geometric algebra (GA) is an efficient tool to deal with hypercomplex processes due to its special data structure. In this article, we introduce the affine projection algorithm (APA) in the GA domain to provide fast convergence against hypercomplex ...

Universal corner symmetry and the orbit method for gravity
Nuclear Physics B, 2023 A universal symmetry algebra organizing the gravitational phase space has been recently found. It corresponds to the subset of diffeomorphisms that become physical at corners – codimension-2 surfaces supporting Noether charges.

UAV’s Agricultural Image Segmentation Predicated by Clifford Geometric Algebra
IEEE Access, 2019 Image segmentation is widely used in the field of agriculture to improve the yields and protecting them from pests, herbs, shrubs, and weeds. Precision agriculture is also contributing to the inter and intra crop monitoring.

Hopf algebras up to homotopy and the Bockstein spectral sequence [PDF]
, 2004 Anick proved that every q-mild Hopf algebra up to homotopy is isomorphic to a primitively-generated chain Hopf algebra. We provide a new proof, that involves extensive use of the Bockstein spectral sequence.Comment: Published by Algebraic and Geometric ...
