Data concerning statistical relation between obliquity and Dansgaard–Oeschger events

open access: yesData in Brief, 2019
Data presented are related to the research article entitled “Using Holo-Hilbert spectral analysis to quantify the modulation of Dansgaard-Oeschger events by obliquity” (J. Deng et al., 2018). The datasets in Deng et al.

Multisensor Data Fusion in IoT Environments in Dempster–Shafer Theory Setting: An Improved Evidence Distance-Based Approach

open access: yesSensors, 2023
In IoT environments, voluminous amounts of data are produced every single second. Due to multiple factors, these data are prone to various imperfections, they could be uncertain, conflicting, or even incorrect leading to wrong decisions. Multisensor data

A new weighting factor in combining belief function. [PDF]

open access: yesPLoS ONE, 2017
Dempster-Shafer evidence theory has been widely used in various applications. However, to solve the problem of counter-intuitive outcomes by using classical Dempster-Shafer combination rule is still an open issue while fusing the conflicting evidences ...

Finite-Temperature Gutzwiller Approximation from Time-Dependent Variational Principle

open access: yes, 2015
We develop an extension of the Gutzwiller approximation to finite temperatures based on the Dirac-Frenkel variational principle. Our method does not rely on any entropy inequality, and is substantially more accurate than the approaches proposed in ...

Quantum information analysis of the phase diagram of the half-filled extended Hubbard model

open access: yes, 2009
We examine the phase diagram of the half-filled one-dimensional extended Hubbard model using quantum information entropies within the density-matrix renormalization group.

A Novel Sensor Dynamic Reliability Evaluation Method and its Application in Multi-Sensor Information Fusion

open access: yesIEEE Access, 2019
The improvement in recognition accuracy of a multi-sensor system is inseparable from the sensors' dynamic reliability, especially in the case of highly conflicting information. Recent research on multi-sensor system has shown that a difficult problem for

A hierarchical loss and its problems when classifying non-hierarchically

open access: yes, 2019
Failing to distinguish between a sheepdog and a skyscraper should be worse and penalized more than failing to distinguish between a sheepdog and a poodle; after all, sheepdogs and poodles are both breeds of dogs.

Weighted Evidence Combination Based on Distance of Evidence and Entropy Function

open access: yesInternational Journal of Distributed Sensor Networks, 2016
Conflict management in Dempster-Shafer theory (D-S theory) is a hot topic in information fusion. In this paper, a new weighted evidence combination on the basis of the distance between evidence and entropy function is presented.
