CS34215 Machine Learning
Introductory description
This module aims to provide students with an indepth introduction to two main areas of Machine Learning: supervised and unsupervised learning.
Module aims
The module covers the main models and algorithms for regression, classification, clustering, and probabilistic classification. Topics such as linear and logistic regression, regularisation, probabilistic (Bayesian) inference, SVMs, neural networks, clustering, and dimensionality reduction are covered. The module primarily uses the Python programming language and assumes familiarity with linear algebra, probability theory, and programming in Python.
