| Research Abstract |
Generalizing the classical k-nearest neighbor method for entropy estimation, an computationally efficient method for estimating information contents of weighted data is proposed. For utilizing our distance-based method to various kinds of data sets, distance metric learning methods are considered in the framework of multiple kernel learning and just-in-time modeling. Validity of those proposed methods are confirmed by clustering problems and ensemble learning of real-world data.
