In recent years, the MP3 music objects become the popular type of music file in many internet audio applications, including the surveillance system. But, less attention was received to the content-based classification of audio data. While Cloud Services were blooming, the classification of MP3 music has better more and more important. It is necessary to process much audio data when Cloud Computing...
In many areas of pattern recognition and machine learning, subspace selection is an essential step. Fisher's linear discriminant analysis (LDA) is one of the most well-known linear subspace selection methods. However, LDA suffers from the class separation problem. The projection to a subspace tends to merge close class pairs. A recent result, named maximizing the geometric mean of Kullback-Leibler...
Traditional algorithm of global dimensionality reduction such as PCA, MDS and Isomap, measure the relation of data by distance, this paper gives an angle measurement approach for the relation of data. Based on the theoretic analysis, a novel angle optimized global embedding (AOGE) algorithm is proposed, which measured the relation of data by the angles between the centralized samples and their orthogonal...
