Regularization Path of Cross-Validation Error Lower Bounds

1 code implementation NeurIPS 2015 Atsushi Shibagaki, Yoshiki Suzuki, Masayuki Karasuyama, Ichiro Takeuchi

Careful tuning of a regularization parameter is indispensable in many machine learning tasks because it has a significant impact on generalization performances.

An Algorithmic Framework for Computing Validation Performance Bounds by Using Suboptimal Models

no code implementations10 Feb 2014 Yoshiki Suzuki, Kohei Ogawa, Yuki Shinmura, Ichiro Takeuchi

If a reasonably good suboptimal model is available, our algorithm can compute lower and upper bounds of many useful quantities for making inferences on the unknown target model.

Safe Sample Screening for Support Vector Machines

no code implementations27 Jan 2014 Kohei Ogawa, Yoshiki Suzuki, Shinya Suzumura, Ichiro Takeuchi

Sparse classifiers such as the support vector machines (SVM) are efficient in test-phases because the classifier is characterized only by a subset of the samples called support vectors (SVs), and the rest of the samples (non SVs) have no influence on the classification result.
