Prof. Corso moved to the Electrical Engineering and Computer Science department at the University of Michigan in the 8/2014. He continues his work and research group in high-level computer vision at the intersection of perception, semantics/language, and robotics. Unless you are looking for something specific, historically, here, you probably would rather go to his new page.

Calendar

Before the course begins, you should review your linear algebra, probability and statistics and calculus notes in preparation for the course.

Lectures from Ng's online ML course reviewing linear algebra are: Ng 13 Ng 14 Ng 15 Ng 16 Ng 17 Ng 18

You should also reacquaint yourself with Matlab (or Octave) and Python/Scipy/Numpy as many examples and voluntary assignments are given in these language/environments.


Ng's tutorial on Octave (a free Matlab-clone) are Ng 26 Ng 27 Ng 28 Ng 29 Ng 30 Ng 31 Ng 32

Python resources are at http://www.cse.buffalo.edu/~jcorso/t/CSE555/python_resources.html .

Code

Code:Background

In order to deepen an understanding of the discussed math and algorithms, students are strongly encouraged to work on their own to complete the assignments and programming materials. A variety of codes will be distributed to the course, in both Matlab and Python formats. Matlab and Octave are readily available on campus. Students are recommended to learn and use Python (i.e., SciPy, NumPy) in the course. Many programming materials given in lecture and many programming aspects of the homeworks will be given in Python. A brief introduction to scientific Python will be given in the course, but it is the students’ responsibility to get up to speed. Additional python resources will be maintained at http://www.cse.buffalo.edu/~jcorso/t/CSE555/python_resources.html .

No work in Java, C/C++, OCaml or other programming environment is contained in this course.

To allow for a common Python environment, the course will officially rely on the Enthough Python Distribution (EPD) http://www.enthought.com/products/epd.php, which is easy to get, free, and includes the packages needed for our material. The course will use EPD version 7.3. Students are encouraged to install it on their own computers, and it is also installed on the CSE network (see https://wiki.cse.buffalo.edu/services/content/enthought-python-distribution for more information).

Code:Access

The professor will make all of the source code discussed in class available to the students. In addition, some pieces of source code will be provided as part of the homework assignments. The source code discussed in the class and the core package is accessible to the students in three ways
  1. Via the web: http://www.cse.buffalo.edu/~jcorso/t/555code/
  2. On the departmental (student) Unix network: /home/csefaculty/jcorso/555code. You can copy the whole directory with rsync: rsync -Cavuz USERNAME@nickelback.cse.buffalo.edu:/home/csefaculty/jcorso/555code .
  3. The directory is actually a bzr repository to which you should have read access. So, you can just pull a copy of the repository (you will not have privileges to commit) with bzr checkout bzr+ssh://USERNAME@nickelback.cse.buffalo.edu//home/csefaculty/jcorso/555code/code This option is particularly of interest because the code will be periodically updated throughout the semester and you will want to have the most recent version.
Note, the source code will be updated periodically throughout the semester and you need to get the latest versions Also, note that toy data is included at the above location as well. It is not in the repository, however.

How to Submit Your Work

No work will officially be submitted as it is home study.
