A Novel Qualitative Maximum a Posteriori Estimation for Bayesian Network Parameters Based on Computing the Center Point of Constrained Parameter Regions

IEEE Access, 2022
Introducing parameter constraints has become a mainstream approach for learning Bayesian network parameters with small datasets. The QMAP (Qualitative Maximum a Posteriori) estimation has produced the best learning accuracy among existing learning ...

Temporal Constraints on Linear BRDF Model Parameters [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2010
Linear models of bidirectional reflectance distribution are useful tools for understanding the angular variability of surface reflectance as observed by medium-resolution sensors such as the Moderate Resolution Imaging Spectrometer. These models are operationally used to normalize data to common view and illumination geometries and to calculate ...

Learning Bayesian Network Parameters With Small Data Set: A Parameter Extension under Constraints Method

IEEE Access, 2020
Recent advances have illustrated substantial benefits from learning Bayesian networks (BNs). However, when the available data size is small, the BN parameter learning becomes a key challenge in many intelligent applications.

Multi-Objective Digital PID Controller Design in Parameter Space and its Application to Automated Path Following

IEEE Access, 2021
This paper presents a multi-objective digital PID controller design method using the parameter space approach of robust control. Absolute stability is treated first by finding the digital PID controller gain parameter space corresponding to closed loop ...

Toward an Optimal Selection of Constraints for Terrestrial Reference Frame (TRF)

Remote Sensing, 2022
Given that the observations from current space geodetic techniques do not carry all the necessary datum information to realize a Terrestrial Reference System (TRS), and each of the four space geodetic techniques has limits, for instance: Very Long ...

Cosmological Parameter Constraints from the SDSS Density and Momentum Power Spectra

The Astrophysical Journal, 2023
We extract the galaxy density and momentum power spectra from a subset of early-type galaxies in the Sloan Digital Sky Survey (SDSS) DR7 main galaxy catalog. Using galaxy distance information inferred from the improved fundamental plane described in Yoon

Solitary Wave and Shock Wave Perturbation for the Modified Kawahara Equation

East European Journal of Physics
This paper retrieves shock waves and solitary wave solutions to the modified Kawahara equation in the presence of perturbation terms. The generalized G'/G-expansion approach is the adopted integration methodology for the model.

Positivity constraints on aQGC: carving out the physical parameter space

Journal of High Energy Physics, 2019
Searching for deviations in quartic gauge boson couplings (QGCs) is one of the main goals of the electroweak program at the LHC. We consider positivity bounds adapted to the Standard Model, and show that a set of positivity constraints on 18 anomalous ...

A Join-Based Hybrid Parameter for Constraint Satisfaction [PDF]

, 2019
We propose joinwidth, a new complexity parameter for the Constraint Satisfaction Problem (CSP). The definition of joinwidth is based on the arrangement of basic operations on relations (joins, projections, and pruning), which inherently reflects the steps required to solve the instance.
