haipinglu/ScalableML: COM6012 Scalable Machine Learning

COM6012 Scalable Machine Learning - University of Sheffield

In this module, we will learn how to do machine learning at large scale using Apache Spark. We will use the High Performance Computing (HPC) cluster systems of our university. If you are NOT on the University's network, you must use VPN (Virtual Private Network) to connect to the HPC.

This edition uses PySpark 3.2.1, the latest stable release of Spark (Jan 26, 2022), and has 10 sessions below. You can refer to the overview slides for more information, e.g. timetable and assessment information.

Session 1: Introduction to Spark and HPC
Session 2: RDD, DataFrame, ML pipeline, & parallelization
Session 3: Scalable decision trees and ensemble models
Session 4: Scalable logistic regression
Session 5: Scalable generalized linear models
Session 6: Scalable neural networks
Session 7: Scalable matrix factorisation for collaborative filtering in recommender systems
Session 8: Scalable k-means clustering and Spark configuration
Session 9: Scalable PCA for dimensionality reduction and Spark data types
Session 10: Apache Spark in the Cloud (guest lecture by Dr Michael Smith)

You can also download the Spring 2021 version for preview or reference.
