Enumeration of Distinct Support Vectors for Interactive Decision Making

no code implementations5 Jun 2019 Kentaro Kanamori, Satoshi Hara, Masakazu Ishihata, Hiroki Arimura

In this paper, we propose a K-best model enumeration algorithm for Support Vector Machines (SVM) that given a dataset S and an integer K>0, enumerates the K-best models on S with distinct support vectors in the descending order of the objective function values in the dual SVM problem.
