Fast and Scalable Structural SVM with Slack Rescaling

no code implementations20 Oct 2015 Heejin Choi, Ofer Meshi, Nathan Srebro

We present an efficient method for training slack-rescaled structural SVM.

Normalized Hierarchical SVM

no code implementations11 Aug 2015 Heejin Choi, Yutaka Sasaki, Nathan Srebro

We present improved methods of using structured SVMs in a large-scale hierarchical classification problem, that is when labels are leaves, or sets of leaves, in a tree or a DAG.
