A Class of Dependent Random Distributions Based on Atom Skipping

no code implementations28 Apr 2023 Dehua Bi, Yuan Ji

We propose the Plaid Atoms Model (PAM), a novel Bayesian nonparametric model for grouped data.

Hi3+3: A Model-Assisted Dose-Finding Design Borrowing Historical Data

no code implementations20 Oct 2020 Yunshan Duan, Sue-Jane Wang, Yuan Ji

Purpose -- Based on a hybrid design that partly uses probability models and partly uses algorithmic rules for decision making, we aim to improve the efficiency of the dose-finding trials in the presence of historical data, maintain safety for patients, and achieve a level of simplicity for practical applications.

Semiparametric Bayesian Inference for the Transmission Dynamics of COVID-19 with a State-Space Model

1 code implementation10 Jun 2020 Tianjian Zhou, Yuan Ji

In particular, we consider a probabilistic extension of the classical susceptible-infectious-recovered model, which takes into account undocumented infections and allows the epidemiological parameters to vary over time.

Consensus Monte Carlo for Random Subsets using Shared Anchors

no code implementations28 Jun 2019 Yang Ni, Yuan Ji, Peter Mueller

Motivated by three case studies, we focus on clustering induced by a Dirichlet process mixture sampling model, inference under an Indian buffet process prior with a binomial sampling model, and with a categorical sampling model.

Clustering valid
