中文简介:
判别学习框架是机器学习领域非常成功的领域之一。这种范例的方法,例如Boosting和支持向量机,通过提高精度和增加机器学习方法的适用性,显着提高了现有技术的分类水平。这些方法的一个主要优点是它们能够在高维特征空间中有效地学习,或者通过使用内核的隐式数据表示或者通过显式特征归纳。但是,传统上这些方法不会利用预测了多个标签的类标签之间的依赖关系。许多现实世界的分类问题涉及多个标签之间的顺序,时间或结构依赖性。我们将研究最近关于在结构化领域中推广歧视性方法的研究。这些技术将动态编程方法的效率与现有技术学习方法的优点相结合。
课程简介: Discriminative learning framework is one of the very successful fields of machine learning. The methods of this paradigm, such as Boosting, and Support Vector Machines have significantly advanced the state-of-the-art for classification by improving the accuracy and by increasing the applicability of machine learning methods. One of the key benefits of these methods is their ability to learn efficiently in high dimensional feature spaces, either by the use of implicit data representations via kernels or by explicit feature induction. However, traditionally these methods do not exploit dependencies between class labels where more than one label is predicted. Many real-world classification problems involve sequential, temporal or structural dependencies between multiple labels. We will investigate recent research on generalizing discriminative methods to learning in structured domains. These techniques combine the efficiency of dynamic programming methods with the advantages of the state-of-the-art learning methods.
