Postoperative delirium (POD) is a common postoperative complication that is relevant to poor outcomes. Therefore, it is critical to find effective methods to identify patients with high risk of POD rapidly. Creating a fully automated score based on an automated machine‐learning algorithm may be a method to predict the incidence of POD quickly.

Attribute discretization is one of the key issues for the Rough Set theory. First, a method is proposed to compute an initial cut points set. The indistinguishable relation of decision tables did not change, and the number of elements in the initial cut points set was reduced. Then, the cut point information entropy was defined to measure the importance of a cut point. Finally, an attribute discretization...
In many data mining tasks, there is a large supply of unlabeled data but limited labeled data since it is expensive generated. Therefore, a number of semi-supervised clustering algorithms have been proposed, but few of them are specially designed for multi-type relational data. In this paper, a semi-supervised k-means clustering algorithm for multi-type relational data is proposed, which is based...
A novel method for self adapting morphological top-hat operator was presented. The structural elements of opening top-hat are trained by utilizing the support vector machine from a mass of sample sets. Once the machine is trained by the samples of structural elements, it can implement background suppressing in the following frames. Practical infrared image sequence background suppressing shows that...
A novel adaptive reference model control design is proposed to approach for a class of nonlinear system. The general description of this system is presented. The conditions of the tracking control scheme are discussed. The design of feed forward matrix and the iterative regulative algorithm of feedback matrix are put forward, which may lead the system to meet a good tracking performance. This kind...
