| Research Abstract |
We developed a method to optimize the distribution of features extracted from a given set of data. The features obtained by the method will follow a distribution, which is suitable for classification task. Though the method is applicable to any classification problem, we applied it to speaker recognition task, and achieved state-of-the-art performance. We also developed information estimators, which quantify the information contents in a datum. We applied the estimators to evaluate the credibility of prediction of solar power generated from solar panel.
