- Linear and non-linear learning.
- Model selection and cross validation.
- Shrinkage methods.
- Kernels and SVMs.
- Ensemble learning (boosting, bagging, random forests).
- Feature engineering.
- Intro to neural networks.
- Extensions: super learners.

#### Learning Outcomes

Subject-specific Knowledge:

- By the end of the module students will:
- have a systematic and coherent understanding of the mathematical theory underlying a variety of machine learning techniques;
- have an understanding of the relationship of this theory to other statistical techniques;
- be able to make appropriate modelling and algorithmic choices for a given problem or application;
- be able to implement those choices in software, and test their validity and performance;
- have an elementary understanding of the functioning and uses of neural networks.

Subject-specific Skills:

- Students will have mathematical skills in the following areas: modelling, optimization, computation.

Key Skills:

- Students will have skills in the following areas: problem formulation and solution, critical and analytical thinking, computer programming.

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Problem classes show how to solve example problems in an ideal way, revealing also the thought processes behind such solutions.
- Computer practicals consolidate the studied material, explore theoretical ideas in practice, enhance practical understanding, and develop practical data analysis skills.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Formative assessments provide feedback to guide students in the correct development of their knowledge and skills in preparation for the summative assessment.
- Computer-based examinations assess the ability to use statistical software and basic programming to solve predictable and unpredictable problems.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
