Task: Briefly review the history of AI (you may make use of the research you carried out for Assessment 1). Be sure to highlight the reasons behind the rise and fall in popularity of AI during the last half century.Bring your discussion up to date with an overview of the current main AI approaches used. Here you should focus on many of the currently popular techniques, including all forms of Machine Learning and Deep Neural Networks.Focus on one sector (e.g. finance, health, commerce, etc.), reviewing the state of the art in terms of the use of AI in that sector.Critically evaluate one particular solution (e.g. a commercial AI product) or approach currently being used.Make sure to properly cite all reference sources (using the Harvard referencing system). Sources such as Wikipedia may be used for background research, but may not be cited in an academic report. The use of diagrams is encouraged where this aids discussion.
