Detecting Nonlinear Causality in Multivariate Time Series with Sparse Additive Models
Yingxiang Yang, Adams Wei Yu, Zhaoran Wang +1
We propose a nonparametric method for detecting nonlinear causal relationship within a set of multidimensional discrete time series, by using sparse additive models (SpAMs). We sho…
Nonparametric Hawkes Processes: Online Estimation and Generalization Bounds
Yingxiang Yang, Jalal Etesami, Niao He +1
In this paper, we design a nonparametric online algorithm for estimating the triggering functions of multivariate Hawkes processes. Unlike parametric estimation, where evolutionary…
Prospect Pricing in Cognitive Radio Networks
Yingxiang Yang, Leonard T. Park, Narayan B. Mandayam +3
Advances in cognitive radio networks have primarily focused on the design of spectrally agile radios and novel spectrum sharing techniques that are founded on Expected Utility Theo…
Efficient Neighborhood Selection for Gaussian Graphical Models
Yingxiang Yang, Jalal Etesami, Negar Kiyavash
This paper addresses the problem of neighborhood selection for Gaussian graphical models. We present two heuristic algorithms: a forward-backward greedy algorithm for general Gauss…
