This report describes our attempt to apply ANFIS (Adaptive Neuro-Fuzzy Inference Systems) for the prediction LD (liver disorder) of people. We use two methods to reduce the input dimensions,then apply to ANFIS for prediction.
This project tries to solve the problem of LD prediction using the ANFIS approach.The problem of LD prediction is concerned with the use of attributes of a specific database, such as its mcv (mean corpuscular volume), alkphos (alkline phosphotase),sgpt (alamine aminotransferase), sgot (aspartate aminotransferase),gammagt (gamma-glutamyl transpeptidase), drinks (number of half-pint equivalents of alcoholic beverages drunk per day) to estimate the healthy of liver.
Our approach to this problem can be explained in two aspects:
Method-1:Principle Component Analysis
Method-2:ANFIS for nonlinear regression
Principle Component Analysis:(input:1,2,6)
