How I write a program 4*3 single layer perceptron network?

The data set contains three species of flowers (classes) setosa, versicolour and virginica.

It contains 3 classes of 50 instances each, where each class refers to a type of iris plant. One class (setosa) is

linearly separable from the other 2; the latter are NOT linearly separable from each other. The database

contains the following attributes in cm: petal width, petal length, sepal width, and sepal length.

...Design and write a program for a 4x3 single layer perceptron network to predict the three species of flowers

setosa, versicolour and virginica in a language of your choice. Use training data for training and testing data

for testing the performance of your design.

a-1. What percentage of the training samples cannot be predicted correctly?
