MACHINE LEARNING METHODS AND BIG DATA - 2022/3
Module code: ECOM075
The availability of high-dimensionality data sets has raised new challenges. Often, for a cross section of n individuals we may observe p individual characteristics, covariates, with p > n; i.e., the number of covariates is larger than the sample size. In this situation, standard econometric techniques fail to work. The key point is that most of the observed covariates have no predictive power and so we want to eliminate them. Data reduction is performed via regularised methods. Machine Learning provides tools for data reduction and for making out-of-sample prediction in the presence of high-dimensionality data, imposing very little structure on the data. Throughout the course, we overview the most popular machine learning methods, such as ridge regressions, LASSO (Least Absolute Shrinkage and Selection Operator), Regression Tree, Random Forest, Boosting and Bagging.

The assessment strategy is designed to provide students with the opportunity to demonstrate that they have achieved the modules learning outcomes.
Thus, the summative assessment for this module consists of:
A coursework assignment that allows students to address an empirical question that involves the use of big data by formalising a hypothesis of interest, selecting an appropriate data reduction and econometric estimation method, and writing their own code using a suitable coding program
An examination that allows students to demonstrate a comprehensive understanding of and ability to evaluate critically machine learning methods
Feedback Individual feedback will be provided on students work during the weekly seminars and when coursework marks are released.
- Provide students with practical knowledge to conduct empirical research that involves big data
- Facilitate a comprehensive understanding of the various machine learning methods
- Enable students to evaluate machine learning methods
- Equip students with the skills to apply each method with real data

Methods of Teaching / Learning
The learning and teaching strategy is designed to enable students to achieve the module¿s learning outcomes. There will be two hours of lectures and one hour of seminar every week. Problem sets based on the methodological topics taught during lectures and computer-based exercises will be reviewed during seminars/tutorials. Students are expected to work on an assignment and actively participate in the seminar hour.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
