Timing and Structure

Easter Term: Weeks 1-4 - 14 lectures + 2 examples classes, 4 lectures/week

Aims

The aims of the course are to:

  • Provide a unified view of information engineering showing how signal processing, computer vision, machine learning and control relate to one another.
  • Use example applications drawn from autonomous driving to provide concrete examples of important concepts and subareas of information engineering including computer vision, machine learning and reinforcement learning
  • Introduce computer vision including algorithms for 3D reconstruction, registration and object recognition
  • Introduce basic concepts in inference, learning and optimisation including maximum-likelihood estimation, Bayes’ rule and gradient descent.
  • Introduce basic algorithms for planning and the general area of sequential decision making / reinforcement learning

Objectives

As specific objectives, by the end of the course students should be able to:

  • Provide example applications of machine perception, machine learning, and autonomous decision making systems.
  • Understand the mathematical basis for perspective projection and feature detection; neural networks and parameter estimation; basic planning and reinforcement learning.
  • Implement methods to solve simple computer vision and machine learning problems including object detection and segmentation and sequential decision making.

Content

A: Introduction to Autonomous Driving (1L) (Guest lecturer from industry)

  • The anatomy of a self-driving car with description of autonomous driving hardware (the car, sensors, interfaces and actuators) 
  • Motivate the need for machine perception (computer vision), learning and decision making systems
  • Important sub-problems in the data processing pipeline: object detection, localisation and mapping, prediction, planning and action
  • Interaction with an example of a self-driving car in Cambridge

It is likely that there will be one guest lecture at the start of the course and one at the end.
