Quarkyonic Matter Equation of State in Beta-Equilibrium

1 code implementation17 Apr 2020 Tianqi Zhao, James M. Lattimer

Quarkyonic stellar models are able to satisfy observed mass and radius constraints with a wide range of model parameters, avoiding the obligatory fine-tuning of conventional hybrid star models, including requiring the transition density to be very close to the nuclear saturation density.

A Likelihood Ratio Framework for High Dimensional Semiparametric Regression

no code implementations6 Dec 2014 Yang Ning, Tianqi Zhao, Han Liu

(i) We develop a regularized statistical chromatography approach to infer the parameter of interest under the proposed semiparametric generalized linear model without the need of estimating the unknown base measure function.

Mode Estimation for High Dimensional Discrete Tree Graphical Models

no code implementations NeurIPS 2014 Chao Chen, Han Liu, Dimitris Metaxas, Tianqi Zhao

Though the mode finding problem is generally intractable in high dimensions, this paper unveils that, if the distribution can be approximated well by a tree graphical model, mode characterization is significantly easier.
