Getting ready

In this recipe, we will introduce the TensorFlow framework, using a simple neural network to classify the iris species. We will use the iris dataset, which has 50 samples from the following species:

• Iris setosa
• Iris virginica
• Iris versicolor

Four features are measured from each sample, namely the length and the width of the sepals and petals, in centimeters.

The following variables are contained:

• Sepal length in cm
  
• Sepal width in cm
  
• Petal length in cm
  
• Petal width in cm
  
• Class: setosa, versicolor, or virginica
