Notions and notations: Babbage's language of thought

Location: CLT 7.01 Date/Time: 21st April 2015, 14:00 - 15:00
Speaker(s): Adrian Johnstone (Royal Holloway, University of London).

Brief Description:'By the aid of the Mechanical Notation, the Analytical Engine became a reality: for it became susceptible of demonstration'. Babbage has been called the 'great-uncle' of modern computing, a claim that rests simultaneously on his demonstrable understanding of most of the architectural principles underlying the modern computer, and the almost universal ignorance of Babbage's work before 1970....

Interactive Memetic Algorithms: New possibilities for social learning

Location: CLT 701 Date/Time: 21st April 2015, 16:00 - 17:00
Speaker(s): Prof. Jim Smith.

Brief Description:Both Memetic and Interactive algorithms have both enjoyed success and popularity within the field of meta-heuristic problem-solving. However, despite the choice of name, and the oft-quoted links to memes as elements of cultural transmission, many aspects of human social learning have been largely ignored to date. In this talk I will examine some of the possibilities for transmission of adaptive behaviour between humans and machines, using examples from our research and suggesting that the rapid advances in interaction technologies offer huge potential for the field to explore.

Augmentative and Alternative Communication across the Lifespan of Individuals with Complex Communication Needs

Location: Room LT5 King George VI building Date/Time: 7th May 2015, 12:00 - 13:00
Speaker(s): Annalu Waller (University of Dundee).

Brief Description:Augmentative and alternative communication (AAC) attempts to augment natural speech, or to provide alternative ways to communicate for people with limited or no speech. Technology has played an increasing role in AAC. At the most simplest level, people with complex communication needs (CCN) can cause a prestored message to be spoken by activating a single switch. At the most sophisticated level, literate users can generate novel text. Although some individuals with CCN become effective communicators, most do not - they tend to be passive communicators, responding mainly to questions or prompts at a one or two word level. Conversational skills such as initiation, elaboration and storytelling are seldom observed.
