![2. The Iris Dataset
What is the accuracy of your new model with one epoch of training?
We are going to use the Iris Dataset, one of the standard data mining data sets which has been around since 1988. The data set contains 3
classes of 50 instances each
1. Iris Setosa
2. Iris Versicolour
3. Iris Virginica
There are only 4 attributes or features:
1. sepal length in cm
2. sepal width in cm
3. petal length in cm
4. petal width in cm
Here is an example of the data:
Sepal Length Sepal Width Petal Length
Class
Iris-setosa
Iris-setosa
Iris-versicolor
Iris-versicolor
Iris-virginica
Iris-virginica
The job of the classifier is to determine the class of an instance (the type of Iris) based on the values of the attributes.
The dataset is available at
