Subject Overview:

AIMS

This subject provides an introduction to probability theory, random variables, decision tests, and stochastic processes. Uncertainty is inevitable in real engineering systems, and the laws of probability offer a powerful way to evaluate uncertainty and make decisions according to well-defined, quantitative principles. The material covered is important in fields such as communications, data networks, signal processing and electronics. This subject is a core requirement in the Master of Engineering (Electrical, Mechanical, Mechatronics and Biomedical).

INDICATIVE CONTENT

Topics include:

  • Foundations – combinatorial analysis, axioms of probability, independence, conditional probability, Bayes’ rule
  • Random variables (rv’s)– definition; cumulative distribution, probability mass and probability density functions; expectation and variance; functions of an rv; important distributions and their properties and uses
  • Multiple random variables – joint cumulative distribution, probability mass and probability density functions; independent rv’s; correlation and covariance; conditional distributions and expectation; functions of several rv’s; jointly Gaussian rv’s
  • Sums, inequalities and limit theorems – sums of rv’s, moment generating function; Markov and Chebychev inequalities; weak and strong laws of large numbers; the Central Limit Theorem
  • Decision testing - maximum likelihood, maximum a posterior, minimum cost and Neyman-Pearson rules; basic minimum mean-square error estimation
  • Stochastic processes – mean and autocorrelation functions, strict and wide-sense stationarity; ergodicity; important processes and their properties and uses.

This material is complemented by exposure to examples from electrical engineering and software tools (e.g. MATLAB) for computation and simulations.

Learning Outcomes:

INTENDED LEARNING OUTCOMES (ILO)

Having completed this subject it is expected that the student be able to:

  1. Demonstrate an understanding of combinatorics, the axioms of probability, independence, random variables, conditioning and Bayes’ rule
  2. Demonstrate an understanding of important distributions, stochastic processes and decision tests, and their significance
  3. Formulate random models of signals and systems encountered in engineering
  4. Calculate and interpret probabilities, probability densities, means, variances and covariances, from given information
  5. Use the law of large numbers, the central limit theorem, and inequalities to find approximations and bounds
  6. Simulate random models using software tools

Assessment:
  • One written examination, not exceeding three hours at the end of semester worth 60%
  • Continuous assessment of submitted project work, not exceeding 30 pages over the semester (approximately 40-45 hours of work per student), worth 30%
  • A one-hour mid-semester test, worth 10%.

Hurdle requirement: Students must pass the written exam to pass the subject.

Intended Learning Outcomes (ILOs) 1 to 5 are assessed in the final written examination, the mid-semester test, and submitted reports for six computer-based workshops.

ILO 6 is assessed through the six workshop reports.

Prescribed Texts:

Probability and Stochastic Processes, Yates and Goodman
