I'm new to machine learning. I'm following this tutorial https://rpubs.com/vitorhs/iris for developing a neural network. I have a doubt the model is able to predict the different class of setosa, versicolor, virginica. but I cant able to extract the predicted results of the model. for example in the above tutorial I can able to see the model has predicted 1 versicolor as virginica and 1 versicolor as virginica. is it possible to extract all the predicted results so it would able to helpful for improving the model.
