Prerequisites

Machine Learning (COMP4670/COMP8600) or Artificial Intelligence (COMP3620/COMP6320) or Information Theory (COMP2610/COMP6261). Students are expected to be familiar with the material in the AI book Russell&Norvig (2010) Chp. 2, 3, 5.2, 5.5, 13, 15.1-2, 17.1-3, 21; and Chapter 1 of Li&Vitanyi (2008), which is a great refresher of basic computability, information, and probability theory.
    The course requires good math and probability skills in general. It is often regarded as (one of) the hardest CS course(s) at ANU, and definitely is more challenging than the three courses above.
    The following self-evaluation may help you determine whether to take this course or not. If you can answer most questions essentially correctly within the suggested time, you are probably prepared for the course. If you have difficulties answering say 3 or more questions even given extra time, the course is probably too difficult for you. Study the material above before you consult the solution.
    Note: If you are planning to do a project with me, excelling in this course is a de-facto prerequisite, since most of my projects require the knowledge taught in this course.

Course Description

This is an advanced undergraduate and graduate course that covers advanced topics in Artificial Intelligence. The course focuses on the foundations of AI, including inductive inference, decision-making, reinforcement learning, information theory, and some game and agent theory. The dream of creating artificial devices that reach or outperform human intelligence is many centuries old. This course presents an elegant parameter-free theory of an optimal reinforcement learning agent embedded in an arbitrary unknown environment that possesses essentially all aspects of rational intelligence. The theory reduces all conceptual AI problems to pure computational questions, and is key to addressing many theoretical, philosophical, and practical AI questions. How to perform inductive inference is closely related to the AI problem. The course covers Solomonoff's theory, which solves the induction problem, at least from a philosophical and statistical perspective. Both theories are based on Occam's razor quantified by Kolmogorov complexity, Bayesian probability theory, and sequential decision theory. The course is for computer science students interested in knowing about or building general AI systems from first principles, and others interested in the formal foundations of intelligence.

Learning Outcomes

While the Introduction to AI course taught a diversity of methods for solving a variety of AI problems, this Advanced AI course emphasizes the foundational, unifying, and general aspects of (artificial) intelligence. Course highlights are:
  • Formal definitions of (general rational) Intelligence;
  • Optimal rational agents for arbitrary problems;
  • Philosophical, mathematical, and computational background;
  • Some approximations, implementations, and applications;
  • State-of-the-art artificial general intelligence.
Despite this grand vision and mission, most of the course necessarily is devoted to introducing the key ingredients of this theory, which are important subjects in their own right. On completing this course students will have a solid understanding of:
  • measures, tests, and definitions of intelligence;
  • Occam's razor;
  • universal Turing machines;
  • algorithmic information theory;
  • probability theory;
  • universal induction;
  • Bayesian sequence prediction;
  • minimum description length principle;
  • intelligent agents;
  • sequential decision theory;
  • reinforcement learning;
  • planning under uncertainty;
  • universal search;
  • Monte-Carlo tree search;
  • philosophical foundations.
This theoretical background enables students at least in principle to analyze and develop generally intelligent systems, with the group project being a first step in this endeavor. Tutorials in the first half of the course will consolidate the knowledge via theoretical exercises. The group project in the second half is about approximating, implementing, and applying the theory to small problems like Tic-Tac-Toe, Poker, and Pacman.

Assignments

Theory Assignment 1: The theory assignment is to be done individually or in groups of two students, and will involve various mathematical exercises that will deepen the understanding of the lectured material. Samuel Yang-Zhao will be tutor and primary contact for the theory assignment.

Practical Group Assignment 2: The practical assignment will be a group project. Goal is to implement the MC-AIXI-CTW model, which is a recent practical scaled-down version of the theoretical universal AI agent AIXI. Students will acquire first-hand experience how a single algorithm can autonomously learn to solve various toy problems like playing Tic-Tac-Toe or PacMan or Poker just based on experience and reward feedback without ever being told the rules of the game. A code skeleton in very light python will be provided, but a group can request to use a different programming language at their own risk. Particular emphasis is on ease of use (installation, compilation, running, modification) and good documentation. The project involves programming of various sophisticated functions, and requires and furthers the understanding of the theoretical material taught in the main class.
    Each group will consist of 5-8 students. A group can self-organize and distribute work internally. The various modules/tasks/domains can be implemented by different students, each responsible for delivering a well-tested module including source and documentation. The group is responsible to deliver a final product consisting of documented source code, experimental results, and a final joint report.
    A Lab director will supervise the practical group project during lab sessions.

Assessment

Hurdle:Initial Hurdle Assessment (pass/fail) in Week 2 or 3 to ensure enrolled students have the required background.
Theory: Individual Theory Assignments (20%). Late submissions will not be accepted, and result in 0 points, hence failure of the course.
Practice: Practical Group Assignment (25%). Late submissions will not be accepted, and result in 0 points, hence failure of the course.
Seminar: Seminar = 5 minute presentation of individual contribution to group assignment (10%).
Exam: Final written examination (45%) Exam (120min, written, closed-book,informal&math questions similar to Ass.1).
Know: What to know for the exam: Material in the course slides.
            The other provided reading material should help you to better understand the slides, but will itself not be examined.
            Math questions will be similar to Assignment 1 but no long or hard proofs. Informal questions test knowledge&comprehension.
Pass: To pass the course, students must pass each assignment and the final exam.
Grading: Final course marks will be subject to moderation, so may differ from the raw sum of assessment marks.
Plagiarism: Misconduct will result in failure of the course and disciplinary consequences (no exceptions)
             and possibly expulsion from the ANU. See: [AcademicHonesty@ANU] [Student Handbook@RSCS]
