5. anew feature extraction algorithm in kernel space is proposed, which uses the bhattacharyya distance as its criterion function
T根據高維核空間的性質，提出了基於bhattach叩a距離準則的核空間特徵提取演算法（ bgye ） 。 -
The data is nonlinearly mapped into high dimensional kernel space at first. then a set of feature vectors can be found such that the bhattacharyya distance of the classes mapped into lower dimensional feature space by feature vectors is maximized. thus the upper
該演算法採用核函數把樣本非線性映射到高維核空間，在核空間中尋找一組最優的特徵向量，把樣本線性映射到低維特徵空間，使類別之間的bhattach刪a距離最大，從而使特徵空間中樣本的baycs分類誤差上界最小。 -
Furthermore, bhattacharyya distance is employed to estimate the similarity between the target model and each hypotheses of the particle filter, which makes the measurement matching and samples ' weight updating more reasonable
