Data Mining

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• Techniques for modelling and extracting features from non-textual data
• Natural language processing techniques for extracting features from text
• Theoretical concepts and the motivations behind different data-mining approaches
• Key concepts, tools and approaches for data mining on complex unstructured data sets (including multimedia mining, Twitter analysis, etc)
• The theory behind modern data indexing systems
• State-of-the-art data-mining techniques including topic modelling approaches such as LDA, clustering techniques and applications of matrix factorisations

Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Solve real-word data-mining, data-indexing and information extraction tasks

Key concepts:

• The importance of data-mining
• Real-world applications of data-mining (cyber-security, financial forecasting, trend prediction, etc)
• What is unstructured data
• - Modalities of data
• Underlying techniques
• - Inverted indexes

Modern data indexing at scale

• Information retrieval models
• Ranking models

Unimodal data mining:

• Topic modelling (techniques such as LSA, pLSA, LDA, NNMF)
• Clustering (Hierarchical agglomerative, Spectral)
• Multi-dimensional scaling
• Mining graphs and networks (hubs and authorities [PageRank/HITS], spectral methods, etc.)
• Finding outliers

Multimodal data mining:

• Finding independent features (e.g ICA, NNMF)
• Finding correlations and making predictions (CL-LSI, classifiers, etc.)
• Collaborative filtering and recommender systems

Summative

This is how we’ll formally assess what you have learned in this module.

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
