Iris Classifier

I have used Multi class decision forest classifier algorithm on two class Iris flower data set to predict flower class and achieve 1 accuracy. I have also used Neural Network regression and multi class neural network classifiers and these were the accuracy of the algorithms- 1. Neural Network Regression - 0.946864 as the IRIS data set contains discrete values rather than continuous values 2. Multi class neural network classifier - 1 3. Multi class decision forest classifier - 1 So I have used multi class decision forest classifier
