In partitional clustering, hard c-means (HCM) (or called k-means) and fuzzy c-means (FCM) are the most known clustering algorithms. However, these HCM and FCM algorithms work worse for data sets in a noisy environment and get inaccuracy when the data set has different shape clusters. For...
The clustering performance of the conventional gaussian kernel based clustering algorithms are very dependent on the estimation of the width hyper-parameter of the gaussian kernel function. Usually this parameter is estimated once and for all. This paper presents a gaussian c-Means with kernelization ...
The existing determination methods largely include K-means clustering algorithms, partition- and density-based clustering algorithms, clustering algorithms based on the local density of data points, and KZZ algorithms. For these, the K-means algorithm is used with a given initial center, whereas ...

Conventional Gaussian kernel c-means clustering algorithms are widely used in applications. However, Gaussian kernel functions have an important parameter, the width hyper-parameter, which needs to be tuned. Usually this parameter is tuned once and for all and it is the same for all variables. ...
