Tables for statistical distributions - t - distribution
统计分布数值表t分布
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
应用方面：我们用多元t分布的有限混合作为数据模型，保证了t - ppca的稳健性，从而比gaussian - ppca更具实用价值。
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 )
具体说来，我们的主要工作包含以下内容：理论方面：假设数据来自m个d元t分布的混合；而每个混合成分均满足迷向( iso - tropic )因子分析模型见3
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
在此学位论文中，我们将gaussian - ppca推广为基于多元t分布的概率pca (下文称为t - ppca ) ，从而得到了一类无论在理论上还是在实际应用中均具有较大意义的通用数据降维算法。
