AdaBoost was proposed as an efficient algorithm of the ensemble learning field, it selects a set of weak classifiers and combines them into a final strong classifier. However, conventional AdaBoost is a sequential forward search procedure using the greedy selection strategy, redundancy can not be avoided. We proposed a post optimization procedure for the(More)
A new method to evaluate the conceptual design of a mechanical system by means of a fuzzy distance measure is proposed. Firstly, all the factors that constrain the conceptual design are established, and the hierarchical relationship among them is set up in terms of usability, dynamic performance, and manufacturability. And then the evaluation criterions are(More)
