Best Subset Selection with Efficient Primal-Dual Algorithm
Shaogang Ren, Guanhua Fang, Ping Li
Best subset selection is considered the `gold standard' for many sparse learning problems. A variety of optimization techniques have been proposed to attack this non-convex and NP-…
Regression with Label Permutation in Generalized Linear Model
Guanhua Fang, Ping Li
The assumption that response and predictor belong to the same statistical unit may be violated in practice. Unbiased estimation and recovery of true label ordering based on unlabel…
Offline Change Detection under Contamination
Sujay Bhatt, Guanhua Fang, Ping Li
In this work, we propose a non-parametric and robust change detection algorithm to detect multiple change points in time series data under contamination. The contamination model is…
Group Network Hawkes Process
Guanhua Fang, Ganggang Xu, Haochen Xu +2
In this work, we study the event occurrences of individuals interacting in a network. To characterize the dynamic interactions among the individuals, we propose a group network Haw…
A Latent Topic Model with Markovian Transition for Process Data
Haochen Xu, Guanhua Fang, Zhiliang Ying
We propose a latent topic model with a Markovian transition for process data, which consist of time-stamped events recorded in a log file. Such data are becoming more widely availa…
Latent Theme Dictionary Model for Finding Co-occurrent Patterns in Process Data
Guanhua Fang, Zhiliang Ying
Process data, temporally ordered categorical observations, are of recent interest due to its increasing abundance and the desire to extract useful information. A process is a colle…
