BN parameter learning based on improved QMAP algorithm under small data set conditions

open access: yesXi'an Gongcheng Daxue xuebao, 2023
Under the condition of Bayesian network (BN) small data set, the qualitative maximum a posteriori (QMAP) estimation tends to violate expert constraints, which causes the QMAP estimation to deviate the true value.

A dual active set algorithm for optimal sparse convex regression

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
The shape-constrained problems in statistics have attracted much attention in recent decades. One of them is the task of finding the best fitting monotone regression. The problem of constructing monotone regression (also called isotonic regression) is to

Bayesian Isotonic Regression and Trend Analysis [PDF]

open access: yesBiometrics, 2004
Summary. In many applications, the mean of a response variable can be assumed to be a nondecreasing function of a continuous predictor, controlling for covariates. In such cases, interest often focuses on estimating the regression function, while also assessing evidence of an association.
