Iris classifier

These 3 irises look quite similar:

Iris setosa	Iris virginica	Iris versicolor

• However, they are indeed 3 different species.
• They differ in lengths and widths of petals and sepals.
• Combination of these measurements allows to distinguish them.

To develop a tool for determining the Iris species, a random forest model was built using iris data from the datasets package.

inTrain=createDataPartition(iris$Species, p=0.75, list=FALSE)
training=iris[inTrain,]
testing=iris[-inTrain,]
model = train(Species ~ ., data=training, method="rf")

pred = predict(model, newdata=testing)
confusionMatrix(pred, testing$Species)$overall[1]

 Accuracy 
0.9166667 

The model was saved as an .RData file and used to build an online application:

The application is available at:
