COMP47650 Deep Learning

Academic Year 2021/2022

Recent advances in machine learning have been dominated by neural network approaches broadly described as deep learning. This module provides an overview of the most important deep learning techniques covering both theoretical foundations and practical applications. The applications focus on problems in image understanding and language modelling and use appropriate state-of-the-art deep learning libraries and tools which are introduced in the module.

Prerequisites: Machine Learning (or similar), strong programming ability (Python or similar languages), strong mathematical ability (especially linear algebra and differential calculus, optimisation)

Learning Outcomes:

On completion of this module students should be able to:
– understand what deep learning means and differentiate it from other approaches to machine learning
– understand loss functions, optimisation and the gradient descent algorithm
– understand the backpropagation of error algorithm in detail and how it is used to train deep neural networks
– distinguish between the most important neural network architectures (e.g. feed forward networks, convolutional neural networks, recurrent neural networks)
– apply appropriate deep learning techniques (e.g. convolutional neural networks, generative adversarial networks...) to image understanding problems (e.g. classification, segmentation, and generation) using open source deep learning frameworks (e.g. TensorFlow, PyTorch)
– apply appropriate deep learning techniques (e.g. dimensional embedding, recurrent neural networks, long short term memory networks, and gated recurrent units) to language modelling problems (e.g. classification, machine translation, and generation) using open source deep learning frameworks (e.g. TensorFlow, PyTorch)
