    讲座题目:Cost-sensitive learning through granular computing Abstract: Cost-sensitive learning is among the top-10 challenging problems in machine learning and data mining. It refers to the learning process with various types of costs, including test cost, misclassification cost, teacher cost, and so on. For classification, we try to minimize the misclassification cost (also called risk) instead of the error. For feature selection, we try to minimize the test cost instead of the number of features. For the tradeoff between the cost and the benefit, we try to minimize the sum of test cost and misclassification cost. For active learning, we try to consult the expert with teacher cost for appropriate data. In this talk, we will discuss granular computing approaches to cost-sensitive learning.
