A Local Modal Outer-Product-Gradient Estimator for Dimension Reduction

Kavli Affiliate: Wei Gao | First 5 Authors: Zheng Li, Chong Ding, Wei Gao, , | Summary: Sufficient dimension reduction (SDR) is a valuable approach for handling high-dimensional data. Outer Product Gradient (OPG) is an popular approach. However, because of focusing the mean regression function, OPG may ignore some directions of central subspace (CS) when […]

Spectral instability of black holes: relating the frequency domain to the time domain

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiqiu Yang, Zhan-Feng Mai, Run-Qiu Yang, Lijing Shao, Emanuele Berti | Summary: Recent work has shown that the quasinormal mode spectrum of black holes is unstable under small perturbations (of order $epsilon$) of the radial potential, while the early time-domain ringdown waveform is only marginally affected. In […]
