A spectral approach for online covariance change point detection
Zhigang Bao, Kha Man Cheong, Yuji Li +1
Change point detection in covariance structures is a fundamental and crucial problem for sequential data. Under the high-dimensional setting, most of the existing research has focu…
Signal detection from spiked noise via asymmetrization
Zhigang Bao, Kha Man Cheong, Jaehun Lee +1
The signal plus noise model is a fundamental model in signal detection when a low rank signal is polluted by noise . In the high-dimensional setting, one often uses…
Flavor Physics at the CEPC: a General Perspective
Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron +147
We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is d…
Reconstruction of Unstable Heavy Particles Using Deep Symmetry-Preserving Attention Networks
Michael James Fenton, Alexander Shmakov, Hideki Okawa +5
Reconstructing unstable heavy particles requires sophisticated techniques to sift through the large number of possible permutations for assignment of detector objects to the underl…
