Nonlinear SVD with Asymmetric Kernels: feature learning and asymmetric Nyström method [PDF]
arXiv, 2023 Asymmetric data naturally exist in real life, such as directed graphs. Different from the common kernel methods requiring Mercer kernels, this paper tackles the asymmetric kernel-based learning problem. We describe a nonlinear extension of the matrix Singular Value Decomposition through asymmetric kernels, namely KSVD. First, we construct two nonlinear

Asymmetric Federalism in India [PDF]
SSRN Electronic Journal, 2004 The focus of this paper is unequal arrangements and special treatment for some units within Indian federalism, namely. We first explore the conceptual issues - the causes and consequences of asymmetric federalism. Next, we trace the evolution of Indian federalism and analyze the factors contributing to the asymmetric arrangements in political ...

Asymmetric Responses of Energy Consumption in Malaysia: Evidence from Nonlinear ARDL
International Journal of Energy Economics and Policy, 2022 Many studies have modelled the prices, growth, technology and financial effects on energy consumption in a linear fashion. However, structural changes may trigger asymmetric or nonlinear behaviour in time series analysis.

On the bifurcation and continuation of periodic orbits in the three-body problem
, 2011 We consider the planar three body problem of planetary type and we study the generation and continuation of periodic orbits and mainly of asymmetric periodic orbits. Asymmetric orbits exist in the restricted circular three body problem only in particular

Optimal multicopy asymmetric Gaussian cloning of coherent states [PDF]
, 2006 We investigate the asymmetric Gaussian cloning of coherent states which produces M copies from N input replicas, such that the fidelity of all copies may be different.

Giant asymmetric second-harmonic generation in bianisotropic metasurfaces based on bound states in the continuum [PDF]
arXiv, 2021 Bianisotropy is a powerful concept enabling asymmetric optical response, including asymmetric reflection, absorption, optical forces, light trapping, and lasing. The physical origin of these asymmetric effects can be understood from magnetoelectric coupling and asymmetrical field enhancement.

String Theories on the Asymmetric Orbifolds with Twist-Untwist Intertwining Currents [PDF]
Prog.Theor.Phys.Suppl.110:261-276,1992, 1992 We give various examples of asymmetric orbifold models to possess intertwining currents which convert untwisted string states to twisted ones, and vice versa, and see that such asymmetric orbifold models are severely restricted. The existence of the intertwining currents leads to the enhancement of symmetries in asymmetric orbifold models.

Global Collapses and Expansions in Star-Forming Clouds
, 2009 Spectral molecular line profile observations of star-forming molecular clouds sometimes show distinct red asymmetric double-peaked molecular line profiles with weaker blue peaks and stronger red peaks.
