Master’s in Financial Mathematics students: MA907 Simulation and Machine Learning.
External Undergraduate students: ST220 Introduction to Mathematical Statistics and ST221 Linear Statistical Modelling.*
Module aims
This module will introduce students to modern applications of Statistics in challenging modern data analysis contexts and provide them with the theoretical underpinnings to apply these methods.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
Statistical Learning – an introduction to statistical learning theory, using simple ML methods to illustrate the various ideas:
From overfitting to apparently complex methods which can work well, such as VC dimension and shattering sets.
PAC bounds. Loss functions. Risk (in the learning theoretic sense) and posterior expected risk. Generalisation error.
Supervised, unsupervised and semisupervised learning.
The use of distinct training, test and validation sets, particularly in the context of prediction problems.
The Bootstrap revisited. Bags of Little Bootstraps. Bootstrap aggregation. Boosting.
Big Data and Big Model – issues and (partial) solutions:
The “curse of dimensionality”. Multiple testing; voodoo correlations, falsediscovery rate and familywise error rate. Corrections: Bonferroni, BenjaminiHochberg.
Sparsity and Regularisation. Variable selection; regression. Spike and slab priors. Ridge Regression. The Lasso. The Dantzig Selector.
Concentration of measure and related inferential issues.
MCMC in high dimensions – preconditioned Crank Nicholson; MALA, HMC. Preconditioning. Rates of convergence.
Learning outcomes
By the end of the module, students should be able to:
 Explain, critically discuss and apply fundamental concepts and analytic tools in Statistical Learning;
 Analyse and discuss issues and fundamental tools in the analysis of Big Data and Big Models;
 Implement and assess methods for prediction based on partitioning data;
 Apply fundamental tools based on sparsity, regularisation and the control of error rates to analyse large data sets.
