Comments:
- Most students did well in this assignment. Your ideas are correct. Just need to improve your skills in expressing ideas clearly, especially when you explaini or justify your solutions.

Problem Definition Assignment 2 (due date: 20 Feb 2009)

Comments:
- Most students attempted to write the problem formulation in an overly complicated fashion.
- Some students talk too much about algorithmic aspects, i.e., the How part.
Problem formulation should focus on the What part.
- A good problem formulation must indicate what is it that needs to be determined.
Just stating that the error E is to be minimized is not sufficient.
E is a function of some parameters. The optimal things to be determined are the parameters that yields the minimum error E.
There are possibly more than one good solution. This is a sample good solution.
This is a
sample poor solution. It is poor because the problem formulation doesn't say much about the problem to be solved.

Problem Definition Assignment 3 (due date: 6 Mar 2009)
|
| |
Comments:
- Most students just use the energy equation of the snake algorithm to define the problem without clearly explaining why that is appropriate.
- In particular, the following items are not clearly explained:
> How does the problem formulation handle the issue of missing edges and noise?
> How does the problem formulation handle the issue of acceptable variations among patients and unacceptable variations of the model?
