Location

Big Data in Finance

  • What is Data science?
  • Supervised and unsupervised learning
  • Structured and unstructured data
  • Introduction to Classification
  • Bayesian Models and inference using Markov chain Monte-Carlo
  • Introduction to graphical models: Bayesian networks, Markov networks, inference in graphical models
  • Optimisation techniques
  • Examples: Predictive analytics/trading & Pricing

Classification, Clustering and filtering

  • Classification: K-nearest neighbours, optimal Bayes classifier, naïve Bayes, LDA and QDA, reduced rank LDA, Logistic regression, Support Vector Machines
  • Cluster analysis: BIRCH, Hierarchical, K-mean, Expectation-maximization, DBSCAN, OPTICS and Mean-shift
  • Kalman filtering
  • Examples (2 worked practical examples)

Machine Learning & Predictive Analytics

  • Regression: liner regression, bias-variance decomposition, subset selection, shrinkage methods, regression in high dimensions
  • Support Vectors Machines: Classification and regression using SVM’s and kernel methods
  • Dimension reduction: Principal component analysis (PCA), kernel PCA, non-negative matrix decomposition, PageRank
  • Examples (2 worked examples)

Big Data Lab

  • Examples

Asset Returns: Key, Empirical Stylised Facts

  • Volatility clustering: the concept and the evidence
  • Properties of daily asset returns
  • Properties of high-frequency returns

Volatility Models: The ARCH framework

  • Why ARCH models are popular
  • The original GARCH model
  • What makes a model an ARCH model?
  • Asymmetric ARCH models
  • Econometric methods

Co-Integration using R

  • Multivariate time series analysis
  • Financial time series: stationary and unit root
  • Vector Autoregression, a theory-free model
  • Equilibrium and Error Correction Model
  • Eagle-Granger Procedure
  • Cointegrating relationships and their rank
  • Estimation of reduced rank regression: Johansen Procedure
  • Stochastic modelling of equilibrium: Orstein-Uhlenbeck process
  • Statistical arbitrage using mean reversion
Lecture order and content may occasionally change due to circumstances beyond our control; however this will never affect the quality of the program.
