A Smoothed Analysis of Online Lasso for the Sparse Linear Contextual Bandit Problem
Zhiyuan Liu, Huazheng Wang, Bo Waggoner +3
We investigate the sparse linear contextual bandit problem where the parameter is sparse. To relieve the sampling inefficiency, we utilize the "perturbed adversary" where the c…
Utilizing Players' Playtime Records for Churn Prediction: Mining Playtime Regularity
Wanshan Yang, Ting Huang, Junlin Zeng +4
In the free online game industry, churn prediction is an important research topic. Reducing the churn rate of a game significantly helps with the success of the game. Churn predict…
Maximum A Posteriori Probability (MAP) Joint Fine Frequency Offset and Channel Estimation for MIMO Systems with Channels of Arbitrary Correlation
Mingda Zhou, Zhe Feng, Xinming Huang +2
Channel and frequency offset estimation is a classic topic with a large body of prior work using mainly maximum likelihood (ML) approach together with Cramér-Rao Lower bounds (CRLB…
Dual Link Algorithm for the Weighted Sum Rate Maximization in MIMO Interference Channels
Xing Li, Seungil You, Lijun Chen +3
MIMO interference network optimization is important for increasingly crowded wireless communication networks. We provide a new algorithm, named Dual Link algorithm, for the classic…
Duality and Optimization for Generalized Multi-hop MIMO Amplify-and-Forward Relay Networks with Linear Constraints
An Liu, Vincent K. N. Lau, Youjian Liu
We consider a generalized multi-hop MIMO amplify-and-forward (AF) relay network with multiple sources/destinations and arbitrarily number of relays. We establish two dualities and…
Stochastic Ordering based Carrier-to-Interference Ratio Analysis for the Shotgun Cellular Systems
Prasanna Madhusudhanan, Juan G. Restrepo, Youjian +3
A simple analytical tool based on stochastic ordering is developed to compare the distributions of carrier-to-interference ratio at the mobile station of two cellular systems where…
