Harmonic mean for subspace selection
Did you know?
WebIn 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, … WebMar 1, 2009 · Harmonic mean for subspace selection (HMSS) (Bian and Tao 2008) and geometric mean-based subspace selection (GMSS) (Tao et al. 2009), are other …
