Building K-Anonymous User Cohorts with\\ Consecutive Consistent Weighted Sampling (CCWS)
Xinyi Zheng, Weijie Zhao, Xiaoyun Li +1
To retrieve personalized campaigns and creatives while protecting user privacy, digital advertising is shifting from member-based identity to cohort-based identity. Under such iden…
Package for Fast ABC-Boost
Ping Li, Weijie Zhao
This report presents the open-source package which implements the series of our boosting works in the past years. In particular, the package includes mainly three lines of techniqu…
pGMM Kernel Regression and Comparisons with Boosted Trees
Ping Li, Weijie Zhao
In this work, we demonstrate the advantage of the pGMM (``powered generalized min-max'') kernel in the context of (ridge) regression. In recent prior studies, the pGMM kernel has b…
One-step exfoliation method for plasmonic activation of large-area 2D crystals
Qiang Fu, Jia-Qi Dai, Xin-Yu Huang +16
Advanced exfoliation techniques are crucial for exploring the intrinsic properties and applications of 2D materials. Though the recently discovered Au-enhanced exfoliation techniqu…
Fast ABC-Boost: A Unified Framework for Selecting the Base Class in Multi-Class Classification
Ping Li, Weijie Zhao
The work in ICML'09 showed that the derivatives of the classical multi-class logistic regression loss function could be re-written in terms of a pre-chosen "base class" and applied…
Nonlinear Photoluminescence in Atomically Thin Layered WSe2 Arising from Diffusion-Assisted Exciton-Exciton Annihilation
Shinichiro Mouri, Yuhei Miyauchi, Minglin Toh +3
We studied multi-exciton dynamics in monolayer WSe2 using nonlinear photoluminescence (PL) spectroscopy and Monte Carlo simulations. We observed strong nonlinear saturation behavio…
