To deal with sensor reliability in evidence modeling, the sensor credibility is evaluated by means of the statistical characters. Then an evidence model based on sensor credibility is established. When modeling, plausibility discount strategy is used to integrate the credibility into the evidence model. The total uncertainty of the evidence model decreases. The simulation example shows that the method...
When evidence theory is used to aggregate large-scale distributed databases, it is often the case that the evidence model has complicated BPA functions. Such an intractable model severely limits the application prospects of evidence theory in this area. In this paper, a compact evidence model is developed to represent uncertain knowledge discovered from large-scale databases. This model categorizes...
Evidence gathered from different sources may have different reliabilities. Such reliability should be integrated into corresponding evidence model to make the evidence combination result rational. In this paper, a novel discounting strategy is developed for the integration of evidence's model and reliability. Dissimilar to the current one based on BPA, this strategy discounts the evidence's plausibility...
