Courses: SYSC 575 / ECE 455/555: Neural Networks I: Winter 2012

Winter 2012, MW, 16:40-18:30, CH 321

Neural networks is a computational and engineering methodology based on emulating how nature has implemented biological brain (in particular, the brain's massively parallel and learning aspects). As such, it holds promise for significant impact on how important classes of scientific and engineering problems are solved. The objective of the this course is to have the students obtain a working knowledge of this forefront technology which is in the midst of a (second) renaissance.

This course covers basic ideas of the neural network (NN) methodology, a computing paradigm whose design is based on models taken from neurobiology and on the notion of "learning." A variety of NN architectures and associated computational algorithms for accomplishing learning are studied. Experiments with various NN architectures are performed via a (commercial) simulation package. Students also use the simulator to complete a classification project.

Topics:

  • introduction and overview of artificial intelligence and neural networks
  • "black-box" representations
  • universal approximation
  • learning methods: supervised, unsupervised, and reinforcement
  • Hebbian learning, delta rule, and generalized delta rule
  • multilayer perceptrons (MLP)
  • radial basis functions (RBF)
  • probabilistic neural networks (PNN) and general regression neural networks (GRNN)
  • Hopfield networks and bidirectional associative memory (BAM)
  • recurrent neural networks (RNN)
  • learning vector quantizer (LVQ) and self-organizing map (SOM)
  • adaptive resonance theory (ART)
  • adaptive critic methods and adaptive dynamic programming (ADP)

Course requirements:

  • reading assignments: short reading assignments to inform class discussions
  • NN simulator experiments and write-ups: short homework assignments using the NN simulator
  • course project (during the last three to four weeks of the term): based on data and a problem context that will be provided, students will select an NN paradigm, perform experiments using the NN simulator, and complete a project report
  • in-class midterm and final exams
