Objectives:
The objectives of this course is to examine the fundamental concepts of neural network computing from the theoretical, as well as from the applications point of view. A variety of neural network architectures with their associated learning algorithms are going to be examined thoroughly. Furthermore, successful applications of neural networks will be discussed. Comparisons of the neural network architectures with already existing approaches will be conducted, whenever data are available.

Prerequisites by Topic:
From the catalog data, it appears that the course has as a prerequisite the Pattern Recognition class (EEL 5825). Although having a background in pattern recognition will help you understand the material of the course faster, EEL 5825 is not a hard prerequisite. In other words, the material presented in this class is self-contained. The mathematical prerequisites are the standard calculus courses, material that is normally covered in the first two years of the standard engineering, computer science, or physics curriculum. Finally, to achieve the full benefit of the material some programming experience in a high-level language, such as C, C++, Fortran or MATLAB is needed.
