摘要:

风险的界在统计学习理论中起着至关重要的作用。他们通常涉及作为研究的VC维度或其扩展之一的模型的容量度量。在分类中,对于在{0,1},{1,.,Q}和R.我们引入了适用于缺失情况的推广,即值为R ^Q的模型。这为我们提供了一个新的保证风险的M-SVM,似乎优于现有的。

英文摘要:

Bounds on the risk play a crucial role in statistical learning theory. They usually involve as capacity measure of the model studied the VC dimension or one of its extensions. In classification, such "VC dimensions" exist for models taking values in {0, 1}, {1,..., Q} and R. We introduce the generalizations appropriate for the missing case, the one of models with values in R^Q. This provides us with a new guaranteed risk for M-SVMs which appears superior to the existing one.
