2007 2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07  
In this paper we present a kernel method for data clustering, where the soft k-means is carried out in a feature space, instead of input data space, leading to soft kernel k-means.  ...  In addition, soft responsibilities as well as geodesic kernel, improve the clustering performance, compared to kernel k-means.  ...  It was shown in [5] that kernel k-means is closely related to spectral clustering and normalized cut.  ...

Hypergraph Modeling via Spectral Embedding Connection: Hypergraph Cut, Weighted Kernel k-means, and Heat Kernel [article]

Shota Saito
2022 arXiv   pre-print
We show a theoretical connection between our formulation and hypergraph cut in two ways, generalizing both weighted kernel k-means and the heat kernel, by which we justify our formulation.  ...  For graph cut based spectral clustering, it is common to model real-valued data into graph by modeling pairwise similarities using kernel function.  ...  As pointed out in (Hein et al. 2013) , the clustering result of normalized cut tends to bias towards large weights. This could enhance existing negative biases as a clustering result.  ...
