Software and Source Code

Any version of NEAT except those with novelty search can be used in the class projects. A number of versions are available here: http://www.cs.ucf.edu/~kstanley/#software

The latest clean version written by myself is rtNEAT, available here. A stripped down version of my non-real-time code is neatVS.zip, refitted for easy compiling by Jared Johnson..

Overview

The purpose of this artificial intelligence (AI) course is to introduce students to current topics in the artificial evolution of complex systems, focusing on evolving neural networks (i.e. neuroevolution). In neuroevolution, a Darwinian survival-of-the-fittest competition among neural networks leads to increasingly sophisticated solutions without the need for human design. However, such a process requires a principled approach to combining, selecting, and encoding large, complex neural networks. The class will also examine sophisticated encoding techniques based on the growth of an embryo from a single cell (i.e. generative and developmental systems) and DNA encoding in nature. Such techniques promise to facilitate the evolution of neural networks with orders of magnitude more complexity than has been heretofore possible. This course will introduce students to the cutting edge of such research, culminating in a project in which students program their own system that evolves increasingly complex structures over time. Neural networks are a good proxy for complex systems in general, exhibiting many of the key properties that make such systems difficult to evolve. The class surveys methods in neuroevolution that have resulted in new ways to produce controllers for a broad range of difficult sequential decision tasks and creative endeavors, including robot and autonomous vehicle control, pattern generation, limb coordination, warning systems, factory optimization, intelligent video games, and computer-generated art and music. Although neural networks are a major focus for the course, students will not be restricted in the type of structure their systems can evolve. In this way, students will become experts through hands-on experience.

Grading Policy

Grades will be based 65% on a final project (10% final presentation and 55% final report), 25% on project milestones, and 10% on quizes on assigned papers. Students must work with a partner and periodically report how they are allocating tasks.

Late policy: 20% off if turned in within one week. Otherwise, not accepted.

Project Milestones (25% of grade; all milestones must be turned in as a hardcopy report):

9/17: Initial proposal and project plan (5%)
9/24: XOR test (5%)
10/6: Domain code prelim (5%)
10/27: Midterm presentation and report (10%)
12/3: Final project and presentation (65% of grade)

Cheating

All of the work that you turn in or present must be your own. Cheating, plagiarism, and any other form of academic dishonesty will be penalized. The minimum penalty for cheating will include:

Plagiarism and paraphrasing are forms of cheating. Plagiarism is the presentation of others' ideas and writings as your own. Paraphrasing is taking someone else's sentence, changing a few words, and then presenting it as your own. Both are unacceptable in this class.
