摘要翻译:
我们提出了一种将先验知识集成到鉴别分类器中的新框架。我们的框架允许像支持向量机这样的鉴别分类器利用生成设置中指定的先验知识。将拟合数据和尊重先验知识的双重目标化为双层规划,通过二阶锥规划迭代求解。为了验证我们的方法,我们考虑了使用WordNet(英语语言语义数据库)来提高新闻组分类的低样本分类精度的问题。WordNet被看作是一个近似的,但却是现成的背景知识来源,我们的框架能够以灵活的方式利用它。

英文摘要:
We present a novel framework for integrating prior knowledge into discriminative classifiers. Our framework allows discriminative classifiers such as Support Vector Machines (SVMs) to utilize prior knowledge specified in the generative setting. The dual objective of fitting the data and respecting prior knowledge is formulated as a bilevel program, which is solved (approximately) via iterative application of second-order cone programming. To test our approach, we consider the problem of using WordNet (a semantic database of English language) to improve low-sample classification accuracy of newsgroup categorization. WordNet is viewed as an approximate, but readily available source of background knowledge, and our framework is capable of utilizing it in a flexible way.
