Assessment Description

Task: Weka Data Mining Practical and Report [15 marks]

There are two steps to complete in this task:

Step 1: You are required to perform a data mining task to evaluate different classification algorithms. Load the breast-cancer.arff data set into Weka and compare the performance on this data set for the following classification algorithms:

• Naive Bayes
• J48
• Random Forest
• Random Tree
• REPTree

Step 2: From step 1 outputs, write a report that shows the performance of the different algorithms and comment on their accuracy using the confusion matrix and other performance metrics used in Weka. In your report consider:

• Is there a difference in performance between the algorithms?
• Which algorithm performs best?

Your report should Include the necessary screenshots, tables, graphs, etc. to make your report understandable to the reader.
