t-distributionの例文
- Tables for statistical distributions - t - distribution
- Applications : as data is modelled as finite mixture of t - distributions , t - ppca is robust in application . comparing with the use of gaussian distribution , our approach does give better results , as is shown by the experiments in chapter 5
- Our main contributions are summarized as what follows : ? theoretical : suppose data were sampled from a mixture of m d - variate t - distributions ; and each mixing component satisfies an isotropic factor analysis model ( see ? . 2 . 1 )
- In this thesis , we derive probabilistic pca , which we call it t - ppca , for data sampled from the finite mixture of multivariate t - distributions , whereby we obtain a new general - purpose dimension reduction algorithm which is of some importance in both theory and application
