Math Modeling II (Fall, 2009)

Instructor: Xin Li (Office Hours: MWF 10:30-11:30)

Classroom: HEC 103

Time: 9:30 - 10:20 MWF

Objectives: We will discuss selected topics from numerical approximation, numerical optimization, and numerical solution of differential equations (both ordinary and partial differential equations) and their applications in solving real world problems in machine learning, image analysis, and computer vision.

Homework assignments and tests: Regular homework will be assigned and graded. Four mid size projects are planned for the semester (for both theory and computing/programming). There will be two mid term tests and a comprehensive final examination.

Grading:

Homework (8) 20 points each
Project (4) 40 points each
Mid term tests (2) 100 points each
Final exam 200 points
TOTAL 720 points

Grade scale: A: over 620 points; B: 520 - 619 points; C: 420 - 519 points; D: 320 - 419; F: less than 320 points
