Large-scale Computing for Data Analytics
11 weeks from 28 Apr to 11 Jul 2025
1 week break starting 2 June
Closing date: 31 Mar 2025 at 12pm
This course aims to introduce learners to efficient implementation of computationally expensive data-analytic methods and data-analytic methods for big data including deep learning and convolutional neural networks, both in terms of applications and implementation in frameworks such as Tensorflow or Keras. This course discusses enterprise-level technology relevant to big data analytics such as Spark, Hadoop and NoSQL databases.
By the end of this course learners will be able to:
- assess and compare the complexity of an algorithm and implementation both in terms of computational time and memory, as well as suggest strategies for reducing those
- describe key concepts of TensorFlow
- perform basic computations with TensorFlow
- distinguish between different types of deep and/or convolutional neural networks and choose an appropriate network for a given problem
- fit a neural network using specialised frameworks such as Tensorflow or Keras and assess the result
- discuss important methodological aspects underpinning deep learning
- explain the differences between SQL and NoSQL databases and assess their suitability in different real-life settings
- explain the basic concepts underpinning big data systems such as Spark or Hadoop and discuss their suitability and use in different scenarios.
Testimonial:
This course has opened my eyes to some of the work I’m likely to be doing in my workplace in the near future. It also helped to explain some topics to me which I’d previously heard of but had not managed to obtain a full understanding of.
