In general, feature extraction can be considered as the process of transforming high dimensional data into a low dimensional feature space based on an optimization criterion. In other words, reducing dimensionality without a serious loss of class separability is the key to feature extraction.
WebThe Chernoff distance is defined and computed in the case of normal density as: (30) where α 1 > 0, α 2 > 0, and α 1 + α 2 = 1. When α 1 = α 2 = 1/2, the Chernoff distance reduces to the Bhattacharyya distance. In [ 25 ], Jebara and Kondon proposed probability product kernel function. WebIn statistics, the Bhattacharyya distance measures the similarity of two probability distributions. It is closely related to the Bhattacharyya coefficient which is a measure of the amount of overlap between two statistical samples or populations. It is not a metric, despite named a "distance", since it does not obey the triangle inequality.
