  • Gas chromatography/mass spectrometry based component profiling and quality prediction for Japanese sake

    Mimura Natsuki , Isogai Atsuko , Iwashita Kazuhiro [他] , Bamba Takeshi , Fukusaki Eiichiro

    … Sake attributes and overall quality were assessed by analytical descriptive sensory test and the prediction model of the sensory score from the component profile was constructed by means of orthogonal projections to latent structures (OPLS) regression analysis. … In addition, we were able to select statistically significant components according to variable importance on projection (VIP). …

  • Speaker Recognition Using Sparse Probabilistic Linear Discriminant Analysis

    YANG Hai , XU Yunfei , ZHAO Qinwei , ZHOU Ruohua , YAN Yonghong

    … In this latent variable model, probabilistic linear discriminant analysis is modified to obtain an algorithm for learning overcomplete sparse representations by replacing the Gaussian prior on the factors with Laplace prior that encourages sparseness. … The variational approximation is also used to compute the likelihood ratio score of all trials of speakers. …

  • 項目と潜在変数との相関を使った項目分析 : 因子負荷量,因子構造そして因子パターンと関係の再考察

    清水 和秋

    … Although the total score of such items is not sufficient for the criterion of the item selection, this rational of the item analysis has been used for the selection the items for scale construction while applying the factor analysis to the same items. … In this note, it is suggested that latent variable like the factor score is more suitable than such sum score for the item analysis. …
