Recovering the number of clusters in data sets with noise features using feature rescaling factors
In this paper we introduce three methods for re-scaling data sets aiming at improving the likelihood of clustering validity indexes to return the true number of spherical Gaussian clusters with additional noise features. Our method obtains feature re-scaling factors taking into account the structure of a given data set and the intuitive idea that different features may have different degrees of...
متن کاملFeature Selection for Small Sample Sets with High Dimensional Data Using Heuristic Hybrid Approach
Feature selection can significantly be decisive when analyzing high dimensional data, especially with a small number of samples. Feature extraction methods do not have decent performance in these conditions. With small sample sets and high dimensional data, exploring a large search space and learning from insufficient samples becomes extremely hard. As a result, neural networks and clustering a...

Classifying Large Data Sets Using SVM with Hierarchical Clusters
Support vector machine (SVM) has been a promising method for classification and regression analysis because of its solid mathematical foundation which conveys several salient properties that other methods do not provide. However, despite the prominent properties of SVM, it is not as favored for large-scale data mining as for pattern recognition or machine learning because the training complexit...
