Imprecise probability and decision in civil engineering : Dempster-Shafer theory and application
Over the last three decades, Bayesian theory has been widely adopted in civil engineering for dealing with uncertainty and for purposes of decision making under uncertainty. However the Bayesian approach is not without criticisms. One major concern has been that information or knowledge, no matter …

Collaborative Intrusion Detection in Federated Cloud Environments using Dempster-Shafer Theory of Evidence
… For collaborative intrusion detection, the Dempster-Shafer (D-S) theory of evidence is applied, executing as a fusion node with the role of collecting and fusing the information provided by the monitoring entities, taking the final decision regarding a possible attack. This type of detection …

Reasoning for Public Transportation Systems Planning: Use of Dempster-Shafer Theory of Evidence
… goals. It applies the belief measures in the Dempster-Shafer theory of evidence as the mathematical mechanism to represent knowledge under uncertainty and ambiguity and to analyze the degree of achievement of stated goals. Three phases are involved in implementing the Belief Reasoning method. …

Information fusion schemes for real time risk assessment in adaptive control systems
… two data fusion techniques, one based on Dempster-Shafer theory and the other based on fuzzy logic. Our techniques were applied to nine flight simulation datasets including those with failures. The monitor fusion algorithms provide unique, meaningful and novel technique for V&V of adaptive …

Uncertainty-aware fusion of foundation and task-specific models for cardiac MRI segmentation
… cardiac MRI segmentation. The approach combines Dempster-Shafer Theory (DST) with an entropy-guided fallback mechanism to perform voxel-wise fusion of calibrated probability maps. DST fusion is applied in regions of agreement, while high-conflict regions are handled by selecting predictions from …

An Evidence Theoretic Approach to Design of Reliable Low-Cost UAVs
… used to evaluate a system's (un)reliability and Dempster-Shafer Theory (Evidence Theory) is used to deal with imprecise failure data. Three unique sensitivity analyses highlight the most cost-effective improvement for the system by either spending money to research a component and reduce …

THE DEVELOPMENT OF A HOLISTIC EXPERT SYSTEM FOR INTEGRATED COASTAL ZONE MANAGEMENT
… yet very few have taken it up. COAMES uses the Dempster- Shafer theory of evidence to reason with uncertainty and importantly introduces the power of ignorance and integration to model the holistic approach. In addition, object orientation enables a modular approach, embodied in the inference …

Uncertainty Assessment in High-Risk Environments Using Probability, Evidence Theory and Expert Judgment Elicitation
… judgment elicitation to probability and evidence theory. This research shows how one type of monotone measure, namely Dempster-Shafer Theory of Evidence can expand the framework of uncertainty to provide decision makers a more robust solution space. The issues imbedded in this research are focused …

Methods for Rigorous Uncertainty Quantification with Application to a Mars Atmosphere Model
… research communities. An expanded formalism for Dempster-Shafer structures is introduced, allowing for the representation of continuous random variables and fuzzy variables as Dempster-Shafer structures. Then, the correctness and incorrectness of probability bounds analysis and the Cartesian …

An integrated approach for multimedia information retrieval.
… multiple retrieval techniques, and the Dempster-Shafer theory of evidence combination is employed for this purpose. The integration of the exact and inexact match retrieval is thereby achieved in one computational model. The framework is supported at the architectural level by developing …

Information selection and fusion in vision systems
… general purpose camera selection based on the Dempster-Shafer theory of evidence. Applied to tracking, it allows tracking people using a dynamic selection of as little as three cameras with the same accuracy as when using up to ten cameras.

Integration of search theories and evidential analysis to Web-wide Discovery of information for decision support
… combined with techniques adapted from grounded theory and Dempster-Shafer theory to significantly enhance the discovery of topic related Web-sourced intelligence. This thesis also describes the development of the new search solution by showing the integration of the mathematical methods used as …

Sliced inverse approach and domain recovery for stochastic inverse problems
… based on rigorous measure-theoretic probability theory that uses all the information encapsulated in both the model and data. We introduce a problem in which a portion of the inputs can be observed and varied to study the hidden inputs, and we employ a formulation of the problem that uses all the …

Agent Trust Management Based on Human Plausible Reasoning and Rough Sets: Application to Agent-based Web search
… for Agent Trust Management (ATM) based on the theory of Rough Sets. ROSTAM is a generic ATM framework that can be applied to any kinds of multi agent systems. However, the features of the application domain must be provided to ROSTAM as trust attributes. By collecting the values for these …
