What skills and knowledge will I gain?

The Postgraduate Diploma in Data Science has been developed by practising data scientists with experience working with major international firms across a wide range of industries. They have identified key skills required for data scientists and have also ensured the course content conforms to the Edison European Data Science Framework’s Body of Knowledge (BoK-DS).
This course is credit-rated at postgraduate level on the European Qualifications framework and carries 60 ECTS credits, which can be transferred to the Institute’s MSc in Data Science and other master's degree programmes.

Postgraduate Diploma  Modules

Exploratory Data Analysis

Most industry analysis starts with exploratory data analysis and a thorough study of this will help you to perform data health checks and provide initial business insights. You will gain a sound understanding of Python and R programming, descriptive statistics, data management and data visualisation. You will also learn SQL for big data pre- processing and prepare data for big data analytics. The module serves as an essential foundation for advanced analytics taught later in the course.
  • Programming basics in Python and R
  • Data management
  • Measures of central tendency and variation
  • Bivariate relationships
  • Data visuallsation

Statistical Inference

Statistical inference is the process of drawing inferences or conclusions from data using statistical techniques. This is at the core of data science, and a strong understanding of statistics from the beginning is the prime ingredient for a competent data scientist. In this module, you will cover sampling, statistical distribution, hypothesis testing, and variance analysis and use R code to carry out various statistical tests and draw inferences from their output.
  • Principles of statistical inference
  • Parametric tests
  • Non-parametric tests
  • Analysis of variance (ANOVA)

Fundamentals of Predictive Modelling

Solutions to many business problems are related to successfully predicting future outcomes. This module introduces predictive modelling and provides a foundation for more advanced methods and machine learning. You’ll gain an understanding of the general approach to predictive modelling and then build simple and multiple linear regression models in Python and R and apply these in a range of contexts.
  • Predictive modelling principles
  • LInear regression models
  • Model validation
  • Python and R packages for predictive modelling

Advanced Predictive Modelling

In this module, you are introduced to model development for categorical dependent variables. Binary dependent variables are encountered in many domains such as risk management, marketing and clinical research and this module covers detailed model building processes. Multinomial and ordinal logisitic regression are also covered.
  • Logistic regression models
  • Survival analysis
  • Cox regression
  • Poisson regression

Time Series Analysis

In this module, time series forecasting methods are introduced and explored. You will analyse and forecast macroeconomic variables such as GDP and inflation, as well as look at complex financial models using ARCH and GARCH, ARIMA, time series regression, exponential smoothing and other models.
  • Time series concepts
  • Assessing stationarity
  • ARIMA, ARCH, GARCH modelling
  • Panel Data Regression

Unsupervised Multivariate Methods

Data reduction is a key process in data science and you will learn to apply data reduction methods such as principal component analysis, factor analysis and multidimensional scaling. You will also learn to segment and analyse large data sets using clustering methods, another key analytical technique that brings out rich business insight if carried out skillfully.
  • Principal Component Analysis
  • Factor Analysis
  • Multidimensional Scaling
  • Cluster Analysis

Machine Learning 1

Machine learning algorithms are new generation algorithms used in conjunction with classical predictive modelling methods. In this Machine Learning 1 module, you will understand applications of the support vector machine, K nearest neighbours and naive bayes algorithms for classification and regression problems using case studies from a range of industries and sectors.
  • Naive Bayes Method 
  • Support Vector Machine Algorithm
  • K nearest neighbours

Machine Learning 2

The Machine Learning 2 module continues developing your machine learning knowledge and you will cover decision tree, random forest and neural network algorithms for regressionand classification, again drawing on case studies from real world data. You will have the opportunity to compare the performance of machine learning algorithms against classical statistical models and learn to assess which are most appropriate for specific scenarios.
  • Decision Tree
  • Random Forest
  • Association Rules
  • Neural Networks

Text Mining and Natural Language processing

This module looks at analysing unstructured data such as that found social media, newspaper articles, videos and more. In particular you will look at methods for text mining and natural language processing using R and Python code to produce graphical representations of unstructured data and carry out sentiment analysis.
  • Structured vs unstructured data
  • Text mining in R and Python
  • Text mining using ggplot2
  • Sentiment analysis using R and Python

Data Science in Practice

The Data Science in Practice module provides you with an opportunity to yor apply knowledge through project work. You will select a project from a specific domain and appropriately apply exploratory data analysis, statistical methods and select appropriate advanced modelling techniques. This module also develops your scientific communication skills through the preparation of project reports and presentations.
  • Presentation and communication skills
  • Synthesis of data science knowledge
  • Application to real world data and scenarios
