Introductory description

Students will study techniques for how to go from raw data to a deeper understanding of the patterns and structures within the data, to support making predictions and decision making.

Module aims

To understand the foundational skills in data analytics, including preparing and working with data; abstracting and modeling an analytic question; and using tools from statistics, learning and mining to address the question

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.

Data Analytics involves being about to go from raw data to a deeper understanding of the patterns and structures within the data, to support making predictions and decision making. The course will cover a number of topic, including:

Introduction to analytics, case studies - How analytics is used in practice. Examples of successful analytics work from companies such as Google, Facebook, Kaggle, and Netflix. Suggestions for the course project.
Basic tools: command line tools, plotting tools, programming tools - The wide variety of tools available to work with data, including unix/linux command line tools for data manipulation (sorting, counting, reformatting, aggregating, joining); tools such as gnuplot for displaying and visualizing data; advanced programming tools such as Perl and Python for powerful data manipulation.
Statistics: Probability recap, distributions, significance tests, R - The tools from statistics for understanding distributions and probability (means, variance, tail bounds). Hypothesis testing for determining the significance of an observation, and the R system for working with statistical data.
Database: Data quality, data cleaning, Relational data, SQL, NoSQL - Problems found in realistic data: errors, missing values, lack of consistency, and techniques for addressing them. The relational data model, and the SQL language for expressing queries. The NoSQL movement, and the systems evolving around it.
Regression: linear regression, least squares, logistic regression - Predicting new data values via regression models. Simple linear regression over low dimensional data, regression for higher dimensional data via least squares optimization, logistic regression for categoric data.
Matrices: Linear Algebra, SVD, PCA - Matrices to represent relations between data, and necessary linear algerbraic operations on matrices. Approximately representing matrices by decompositions (Singular Value Decomposition and Principal Components Analysis). Application to the netflix prize.
Clustering: hierarchical, k-means, k-center - Finding clusters in data via different approaches. Choosing distance metrics. Different clustering approaches: hierarchical agglomerative clustering, k-means (Lloyd's algorithm), k-center approximations. Relative merits of each method.
Classification: Trees, NB, Support Vector Machines, Kernel Trick - Building models to classify new data instances. Decision tree approaches and Naive Bayes classifiers. The Support Vector Machines model and use of Kernels to produce separable data and non-linear classification boundaries. The Weka toolkit.
Data Structures: Bloom Filters, Sketches, Summaries - Data structures to scale analytics to big data and data streams. The Bloom filter to represent large set values. Sketch data structures for more complex data analysis, and other summary data structures.
Data Sharing: Privacy, Anonymization, Risks - The ethics and risks of sharing data on individuals. Technologies for anonymizing data: k-anonymity, and differential privacy.
Graphs: Social Network Analysis, metrics, relational learning - Graph representations of data, with applications to social network data. Measurements of centrality and importance. Recommendations in social networks, and inference via relational learning.
