The Informational Complexity of Learning from Examples

This thesis attempts to quantify the amount of information needed to learn certain tasks. The tasks chosen vary from learning functions in a Sobolev space using radial basis function networks to learning grammars in the principles and parameters framework of modern linguistic theory. These problems are analyzed from the perspective of computational learning theory and certain unifying perspectives emerge.

Interactions between grain size and composition of sediments: two examples

Two contrasting case studies of sediment and detrital mineral composition are investigated in order to outline interactions between chemical composition and grain size. Modern glacial sediments exhibit a strong dependence of the two parameters due to the preferential enrichment of mafic minerals, especially biotite, in the fine-grained fractions. On the other hand, the composition of detrital heavy minerals (here: rutile) appears to be not systematically related to grain-size, but is strongly controlled by location, i.e. the petrology of the source rocks of detrital grains. This supports the use of rutile as a well-suited tracer mineral for provenance studies. The results further suggest that (i) interpretations derived from whole-rock sediment geochemistry should be flanked by grain-size observations, and (ii) a more sound statistical evaluation of these interactions require the development of new tailor-made statistical tools to deal with such so-called two-way compositions

What is Abstinence? Definitions and Examples of Abstinence, to Prevent the Sexual Transmission of the HIV Virus, According to Spanish University Students

Research carried out in several Anglo-Saxon countries shows that many undergraduates identify oral sex and anal sex as examples of abstinent behaviour, while many others consider kissing and masturbation as examples of having sex. The objective of this research was to investigate whether a sample of Spanish students gave similar replies. Seven hundred and fifty undergraduates (92% aged under 26, 67.6% women) produced examples or definitions of the term ‘abstinence’. Spanish students made similar errors to those observed in the Anglo-Saxon samples, in that behaviours that were abstinent from a preventive point of view (masturbating and sex without penetration) were not considered as such, while a number of students reported oral sex as abstinent behaviour. The results suggest that the information on risky and preventive sexual behaviour should cease to use ambiguous or euphemistic expressions and use vocabulary that is clear and comprehensible to everyone

WAIS Seminar:Modelling the Web: Examples of modelling language, network evolution and physical-social systems

Speaker(s): Prof. Steffen Staab Organiser: Dr Tim Chown Time: 23/05/2014 10:30-11:30 Location: B53/4025 Abstract The Web is constructed based on our experiences in a multitude of modalities: text, networks, images, physical locations are some examples. Understanding the Web requires from us that we can model these modalities as they appear on the Web. In this talk I will show some examples of how we model text, hyperlink networks and physical-social systems in order to improve our understanding and our use of the Web.
