Your paper should have an Introduction, five “body” parts (approach 1, approach 2 and approach 3, similarities between approaches, and differences between approaches) appropriately titled, and a Conclusion. In each of the first three body parts, you must describe the approach, note the data needed to apply the technique, and discuss limitations or challenges to properly executing the approach. In the next two sections you need to clearly demonstrate what the approaches have in common and how they differ.
