PG-HMI:Mutual Information Based Feature Selection Method
Sun Pyo Hong · 2007
Conventional sample-based mutual information estimation methods can't handle the mixed features directly that include both numeric attributes and nominal attributes.A Parzen window based general mutual information calculation method,PG method,is proposed in this paper, which could deal with the mixed attributes directly.A criterion named hybrid mutual information (HMI)is presented.Based on PG mutual information estimation method and HMI feature selection criterion,a feature selection algorithm(PG-HMI)is proposed.Experimental results show the correctness of PG and the effectiveness of PG-HMI.
