Spectral analysis-based dimensionality reduction algorithms are important and have been popularly applied in data mining and computer vision applications. To date many algorithms have been developed, e.g., principal component analysis, locally linear embedding, Laplacian eigenmaps, and local tangent space alignment. All of these algorithms have been designed intuitively and pragmatically, i.e., on...
K-means is a widely-used clustering algorithm in data mining. In traditional algorithm, each feature is treated equally and each one gives the same contribution to K-means. In fact, redundant and irrelevant features may disturb the clustering result. This paper proposes a improved K-means algorithm based on a fuzzy feature selection strategy. The method is based on measuring 'feature important factor'...
Clustering is one of the most heated topics in data mining research. In traditional clustering algorithms, each feature is treated equally and each one does the same contribution to clustering. As a matter of fact, redundant and unrelated features may disturb the clustering result. This paper proposed a fuzzy feature selection strategy to improve the clustering algorithm. The strategy is based on...
