Optimal discriminant plane is an important feature extraction method in machine learning, pattern recognition and image processing, etc. Based on this, Zhao et al. presented a hybrid optimal discriminant plane method by integrating uncorrelated and orthogonal discriminant vectors together. As the same to optimal discriminant plane, it is a supervised feature extraction method. This paper extends Zhao's...
Optimal discriminant plane based on Fisher criterion function is an important supervised feature extraction method and has great influence in the area of pattern recognition. In this paper, an extension of optimal discriminant plane in unsupervised pattern is presented. The basic idea is to optimize the defined fuzzy Fisher criterion function to figure out an optimal discriminant vector and fuzzy...
