I've done some searching through the archives, and I've found some Mahalanobis-based programs, but none that do the clustering step. I'm wondering: -if this exists, and I just couldn't find it; -if it doesn't exist, is there a reason why not - some limitation or reason I'm not...

clustering algorithm,it combines Mahalanobis distance with the K-means and adds a variable weighting factor and a regulating factor of covariance matrix to each class in the objective function.Using the advantage of Mahalanobis distance,it effectively solves the shortcomings of K-means clustering ...

When the surface is too complex to be neatly partitioned into two clearly disjoint surfaces, the use of the Mahalanobis distance metric can produce an imbalanced partitioning. Here one can use a hybrid strategy: first try a k-means clustering based on the Mahalanobis metric, and if that ...
权重马氏距离 1. To obtain a better segmentation result,this paper used Weighted Mahalanobis Distance(WMD) Gaussian kernel for Nystr m-Ncut segmentation. 为了使经典谱分割的Nystr m采样快速算法得到更清晰的结果,将权重马氏距离高斯核应用于其中,相对于常用的马氏距离高斯核,得到了更好的分割效果。补充...

Mahalanobis distance in reproducing kernel Hilbert space (RKHS) allows for a customized approach to measuring dissimilarity between data points, taking into account their underlying distribution and relationships. This technique enables the identification of alternative clusterings by considering the intrinsic ...

distance between similar data points is small [22].Thus it can enhance the performance of clustering or classification algorithms,such as KNN classifier.Such advantages can be used to perform spe-cial tasks on a given data set, if given a suitable Mahalanobis distance metric. It is natural to...
