Adaptive label thresholding methods for online multi-label classification
Tingting Zhai, Hongcheng Tang, Hao Wang
Existing online multi-label classification works cannot well handle the online label thresholding problem and lack the regret analysis for their online algorithms. This paper propo…
Instability of de-Sitter black hole with massive scalar field coupled to Gauss-Bonnet invariant and the scalarized black holes
Zhen-Hao Yang, Guoyang Fu, Xiao-Mei Kuang +1
The black hole scalarization in a special Einstein-scalar-Gauss-Bonnet (EsGB) gravity has been widely investigated in recent years. Especially, the spontaneous scalarization of sca…
Classification of Teleparallel Horndeski Cosmology via Noether Symmetries
Konstantinos F. Dialektopoulos, Jackson Levi Said, Zinovia Oikonomopoulou
Teleparallel Horndeski theory offers an avenue through which to circumvent the speed constraint of gravitational waves in an efficient manner. However, this provides an even larger…
A note on the dynamical system formulations in gravity
Saikat Chakraborty, Peter K. S. Dunsby, Kelly Macdevette
A number of dynamical system formulations have been proposed over the last few years to analyse cosmological solutions in gravity. The aim of this article is to provide a br…
Self-consistent Effective-one-body theory for spinless binaries based on post-Minkowskian approximation I: Hamiltonian and decoupled equation for
Jiliang Jing, Shuai Chen, Manman Sun +3
To build a self-consistent effective-one-body (EOB) theory, in which the Hamiltonian, radiation-reaction force and waveform for the "plus" and "cross" modes of the gravitational wa…
Critical phenomena in dynamical scalarization of charged black hole
Cheng-Yong Zhang, Qian Chen, Yunqi Liu +3
We report a new black hole scalarization mechanism and disclose novel dynamical critical phenomena in the process of the nonlinear accretion of the scalar field into black holes. T…
