Paper presentation, term paper and project
Divided into groups of 2-3 8-10 papers will be identified. Each group will be expected to:
Select a paper. Read the paper and understand the technique described. Present the technique to the class. Summarize the technique in a 1-2 page paper. Questions will be provided to the students, answers to
which should be included in the term paper. Implement the technique described in the paper using
language/package of your choice.•Additional I/O requirements may be specified.
Demonstrate the implementation.
