Problem description and pipeline Case study focused around photo OCR Three reasons to do this 1) Look at how a complex system can be put together 2) The idea of a machine learning pipeline What to do next How to do it 3) Some more interesting ideas …
Learning with large datasets This set of notes look at large scale machine learning – how do we deal with big datasets? If you look back at 5-10 year history of machine learning, ML is much better now because we have …
Recommender systems – introduction Two motivations for talking about recommender systems Important application of ML systems Many technology companies find recommender systems to be absolutely key Think about websites (amazon, Ebay, iTunes genius) Try and recommend new content for you based on …
Anomaly detection – problem motivation Anomaly detection is a reasonably commonly used type of machine learning application Can be thought of as a solution to an unsupervised learning problem But, has aspects of supervised learning What is anomaly detection? Imagine you’re an aircraft engine manufacturer …
Motivation 1: Data compression Start talking about a second type of unsupervised learning problem – dimensionality reduction Why should we look at dimensionality reduction? Compression Speeds up algorithms Reduces space used by data for them What is dimensionality reduction? So you’ve collected many …
