Michaelmas term. 14 lectures + 2 examples classes. Assessment: 100% exam
Prerequisites
Part IIA Modules 3F1, 3F3 and 3F8 advisable
Aims
The aims of the course are to:
- This module aims to teach the basic concepts of deep learning and forms of structure that can be used for generative and discriminative models. In addition, the use of models for classifying structured data, such as speech and language, will be discussed
Objectives
As specific objectives, by the end of the course students should be able to:
- Understand the basic principles of pattern classification and deep learning;
- Understand generative and discriminative models for structured data;
- Understand the application of deep-learning to structured data;
- Be able to apply pattern processing techniques to practical applications.

Links with 3F8 and 4F13. General machine learning, examples of structured data, DNA, vision, speech and language processing.
Decision Boundaries and Probability of Error (1L)
Definition of a decision boundary and forms that result from Gaussian class-conditional probability density functions. Calculation of probability of Error.
Graphical Models and Conditional Indpendence (1L)
Graphical models and Bayesian networks. Simple inference examples.
Latent Variable and Sequence Models (3L)
