Question: IRIS dataset is perhaps the most widely used dataset by researchers in the pattern recognition literature. The dataset contains 150 instances of 3 different Iris

IRIS dataset is perhaps the most widely used dataset by researchers in the pattern recognition literature. The dataset contains 150 instances of 3 different Iris plant divided into 3 classes. One of the classes is linearly separable from the other 2, whereas the remaining 2 are not from each other. These Iris plants are Iris Setosa, Iris Virginica, and Iris Versicolour. The Iris plants has 4 features, Sepal length, Sepal width, Petal length, and Petal width. Using WEKA software, answer the following questions based on the Iris dataset provided. a) Transform the data by correcting the error in the dataset in instance number 35 and 38 (Iris Sentosa). It should read 4.9,3.1,1.5,0.2 (error is in the fourth feature) and 4.9,3.6,1.4,0.1 (error in third and fourth features) respectively. b) Use the Hierarchical Cluster (number of clusters as 3) and compare it with the SimpleKMeans (also number of clusters set as 3). c) Change the number of clusters to 2 for both. Explain what you observe when compared to 3 clusters. What could be the reason for the difference? d) Which of these 2 algorithms is better in clustering the Iris dataset? Why?
