Modeling Function-Valued Processes with Nonseparable and/or Nonstationary Covariance Structure

1 code implementation24 Mar 2019 Evandro Konzen, Jian Qing Shi, Zhanfeng Wang

We discuss a general Bayesian framework on modeling multidimensional function-valued processes by using a Gaussian process or a heavy-tailed process as a prior, enabling us to handle nonseparable and/or nonstationary covariance structure.

Active learning for binary classification with variable selection

no code implementations29 Jan 2019 Zhanfeng Wang, Yumi Kwon, Yuan-Chin Ivan Chang

For a classification problem, this means that the essential label information may not be readily obtainable, in the data set in hands, and an extra labeling procedure is required such that we can have enough label information to be used for constructing a classification model.

Distributed sequential method for analyzing massive data

no code implementations22 Dec 2018 Zhanfeng Wang, Yuan-Chin Ivan Chang

To analyse a very large data set containing lengthy variables, we adopt a sequential estimation idea and propose a parallel divide-and-conquer method.
