- Abstract:
-
In practice, redundant features and outliers (noise) in data points heavily influence the discovery of more prominent features in clustering and significantly impair clustering performance. In this study, we propose a spectral clustering (SC) based on extreme machine learning as autoencoder (ELM-AE) feature representation (SC-ELM-AE). ELM-AE learns the principal feature representation of the source data via singular value decomposition and uses the output weights to realize reconstruction from feature representation space to the original input data. The reconstructed feature representation space is fed to the SC as input. The experimental results show that the proposed algorithm is 30% more accurate in the average clustering than the conventional K-means, SC, and other existing algorithms in the verification of five UCI datasets, particularly on complex high-dimensional datasets, such as PEMS-SF and TDT2_10.
