Enhanced iterative projection for subclass discriminant analysis under EM-alike framework
作者:
Highlights:
• We focus on the classification of the large sample size problems.
• We propose a new EM-alike iterative projection approach (EMIPA) for subclass division.
• Our proposed approach outperforms the traditional MDA and SDA.
• Our approach operates subclass division and eigenvector seeking class by class.
• Our proposed approach takes only a bit more time than MDA and SDA.
