A new method is proposed in this paper to determine the rejection thresholds. First, the minimum risk decision rules are analyzed and the cost function is founded. After taking into account the rejection cost, the cost function is modified and the requirement that the rejection thresholds shall satisfy to minimize the cost function is given. Second, the property of ROC is analyzed based on conditional...
D-S evidence theory has been widely used in various fields of information fusion due to its efficiency in dealing with uncertain information. Unfortunately, combination of conflicting evidences with the classical Dempster's rule may produce the counter-intuitive results. In this paper, Definitions of correlation coefficient and credibility are first presented, followed by the introduction of evidence...
This paper gave a visually interval algorithm for the global optimal solution to solve the problem of the constraint global optimization. This algorithm ensured that the problem cannot fall into the local optimal solution and improved the convergence speed through using local lipschitz constants. This paper proved the convergence of the algorithm, and numerical examples showed that the algorithm is...
