This course explores a selected area relevant to statistical machine learning in depth, and will be taught by an SML staff member of internationally recognised standing and research interest in that area. Based on current SML staffing, this will be one of:


•    kernel methods
•    graphical models
•    reinforcement learning
•    convex analysis
•    optimisation
•    bioinformatics
•    minimal description length principle
•    topics in information theory
•    decision theory


Over the past several years the content has alternated between “convex analysis and optimisation” and “structured probabilistic models”. Students should contact the course convenor to find out what topic is planned for the coming semester.

Learning Outcomes

The learning outcomes change based on the area taught. For the convex analysis and optimisation topic, at the end of the course students should be able to:
  •  Distinguish definitions of key concepts in convex analysis, including convexity of sets and functions, subgradients, and the convex dual
  •  derive basic results about convex functions such as Jensen’s inequality
  •  Deduce how Bregman divergences are constructed from convex functions and derive some of their properties
  •  Produce a formal optimization problem from a high-level description and determine whether the problem is convex
  •  Recognize standard convex optimization problems such as linear programs and quadratic programs
  •  Derive the standard (dual) quadratic program for support vector machines and understand the extension to max-margin methods for structured prediction
  •  Implement and analyse gradient descent algorithms such as stochastic gradient descent and mirror descent
For the structured probabilistic models topic, at the end of the course the student should be able to:
  • Distinguish definitions of key concepts in probabilistic graphical models, including Bayesian networks, Markov networks, probabilistic queries, and conditional independence
  • Derive independence assumptions from graphical representations of a probabilistic model
  • Contrast and implement various exact and approximate inference algorithms, including belief propagation of trees, sampling, and variational schemes
  • Derive maximum likelihood learning for probabilistic graphical models
  • Demonstrate advanced understanding of approximations of the likelihood function

Indicative Assessment

Assessment will be in the form of regular assignments and an open-book final examination.

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
