    Back to the Future

    Back to the Future

    In March 2008, the University hosted the Science and Technology Research Institute (STRI) Showcase, its second showcase of research. The following lecture was given by Professor Bruce Christianson, Professor of Informatics at the University, on the challenge to make computer programs run backwards, a necessary development for Science and Engineering to move forward. According to Professor Christianson, moving from simulating a process to optimising the underlying model requires accurate sensitivities, and when there are many thousands of inputs these sensitivities are most efficiently calculated in reverse. Professor Christianson and his international team are developing the world's first complete Adjoint (backwards) Fortran Compiler to make this possible.

    Relevant information: Lecture

    How do we know when some information is relevant? In this lecture, Luciano Floridi introduces the general debate on informational relevancy in a variety of contexts (including search engines, information retrieval, online advertising, juridical procedures, everyday information processes, medical diagnosis, and scientific experiments). He then presents a general theory of relevant information and shows how it provides a satisfactory answer to the initial question.

    This second part of the lecture series gives the formal foundation of information theory which will be useful to fully appreciate the final lecture in the series. While slightly more formal than the rest of the series, the lecture does not assume much beyond some elementary mathematics.

    Information Currency of Life 1

    This first part of the lecture series travels over a series of phenomena observed in living nature which carry the hallmark of intelligent behaviour and asks how these could emerge through evolution. The lecture accumulates evidence that points to the requirements of sensorimotor structure and the cost of information processing as the main suspects.
