Workshop in Mixture Estimation and Applications, Edinburgh, March 3-5, 2010

WORKSHOP IN MIXTURE ESTIMATION AND APPLICATIONS
International Centre for Mathematical Sciences (ICMS)
Edinburgh, March 3-5, 2010
Organisers: Kerrie Mengersen, Christian Robert, Mike Titterington
http://www.icms.org.uk/workshops/mixture

Statistical mixture distributions are used to model scenarios in which certain variables are measured but a categorical variable is missing. For example, although clinical data on a patient may be available their disease category may not be, and this adds significant degrees of complication to the statistical analysis. The above situation characterises the simplest mixture-type scenario; variations include, among others, hidden Markov models, in which the missing variable follows a Markov chain model, and latent structure models, in which the missing variable or variables represent model-enriching devices rather than real physical entities. In the title of the workshop the term ‘mixture’ is taken to include these and other variations along with the simple mixture. The motivating factors for this three-day workshop are that research on inference and computational techniques for mixture-type models is currently experiencing major advances and that simultaneously the application of mixture modelling to many fields in science and elsewhere has never been so rich. We thus assembling top players, from statistics and computer science, in both methodological research and applied inference at this fertile interface. The methodological component will involve both Bayesian and non-Bayesian contributions and biology and economics will feature strongly among the application areas to be covered.

The following people have agreed to give talks or invited discussion contributions: John Geweke, Sylvia Fruhwirth-Schnatter, Gilles Celeux, Agostino Nobile, Murray Aitkin, Geoff McLachlan, Jihua Chen, Bruce Lindsay, Michael Jordan, Yee Whye Teh, Chris Williams, Mark Girolami, Katherine Heller, Christophe Andrieu, Paul Fearnhead, Arnaud Doucet, Olivier Cappe, Kim-Anh Do, Peter Mueller, Michael Newton, Chris Holmes, Robert Kohn, Hedibert Lopes and Richard Gerlach.

Statistical Mechanics approaches to Systems Biology

Several 4-year BBSRC-funded studentships available

We expect to have a number of BBSRC-funded studentships available in the area of Systems Biology, focussing on the mathematical analysis of dynamical processes on biological networks (e.g. protein interaction networks) using techniques from Statistical Mechanics. Projects will be supervised in close collaboration between members of the Disordered Systems group in the Department of Mathematics at King’s College London, and members of the Randall Division of Cell and Molecular Biophysics and of the Bioinformatics group in the Department of Medical and Molecular Genetics

The proposed projects cover topics including

* Mathematical theory of gene regulation networks – from interacting microscopic components to macroscopic behaviour

* Statistical mechanics of complex formation in large molecules

* How do we account for what we don’t know? – The effects of incomplete knowledge on the dynamics of protein interaction networks: from statistical physics and machine learning to experiment

Further details and project descriptions can be found at http://www.mth.kcl.ac.uk/~psollich/BBSRC/

Suitable candidates for these studentships should have a first or upper second class degree in mathematics, theoretical physics or a related discipline with a strong mathematical component. They must be U.K. citizens or have another relevant connection with the U.K., which normally amounts to having been resident in the U.K. for 3 years or more (see http://www.bbsrc.ac.uk/funding/studentships/studentship_eligibility.pdf). Studentships are fully funded and provide all course fees for the 4-year Ph.D. programme, as well as a stipend of around GBP15,000/year.

The deadline for applications is expected to be in late December 2009, or early January 2010. In the mean time, interested candidates are encouraged to contact the 1st supervisors for the proposed projects for further information (see http://www.mth.kcl.ac.uk/~psollich/BBSRC/); please attach a CV. At the time of application, students would also need to provide a list of three projects in order of preference. Studentships will be awarded competitively following shortlisting and interviews, after which allocation of students to projects will be finalized. Studentships would be expected to be taken up in Sept 2010.

MASH: Phd and post-doc positions in machine learning

* ABSTRACT

The MASH project is a three-year research initiative which brings
together five institutions with expertise in statistics, machine
learning, goal planning and computer vision to investigate the
collaborative design of complex hand-designed priors for machine
learning.

MASH is funded by the Information and Communication Technologies
division of the European Commission, Cognitive Systems and Robotics
unit, under the 7th Research Framework Programme.

Research will start in January 2010 and will be carried out in
Switzerland (IDIAP), France (CNRS and INRIA), Germany (WIAS) and
Czech Republic (CVUT). Open positions are listed below.

You can already register on http://www.mash-project.eu to get
updated by mail on the status of the project.

* SUMMARY

The goal of the MASH project is to create new tools for the
collaborative development of large families of feature extractors.
It aims at starting a new generation of learning software with
great prior model complexity.

The project is structured around a web platform which will be open
to external contributors early in 2010. It comprises collaborative
tools such as a wiki-based documentation and a forum, and an
experiment center which runs and analyzes experiments on a
continuous basis.

The applications targeted by the project are classical vision
problems, and goal-planning in a 3D video game and with a real
robotic arm.

Contributors will participate to the project by uploading the
source codes of “feature extractors” into the platform. Each one of
these extractors processes an input image to generate values
relevant to the system. This purposely broad definition spans from
classical vision processing such as edge detector or color
histogram estimation, to highly dedicated hand-designed templates
or event-based memory for the robotic applications. The system
concatenates all these extractors to create a very large feature
vector, which is used as an input signal for a machine learning
algorithm.

In practice, anybody can upload such a module at any time. It will
be immediately compiled and integrated in the next starting
experiment. Preliminary performance measures will be provided in a
matter of minutes, and complete results a few hours later. The
system encourages contributors to improve upon the work on other
and focus on the main weaknesses of the overall system.

The scientific issues to be tackled along the course of the project
are numerous, from standard machine learning questions such as
learning and prediction with very large feature spaces and tight
computational constraints, to original problems related to
clustering in a functional space.

The School of Technology wishes to strengthen its research base with the appointment of two Readers, one in an area of computer science and the other in an area of engineering. We are looking for individuals who will take a leading role in the development of research and knowledge transfer, including management of PhD students and research groups where appropriate.

The Computer Vision group in the Department of Computing was formed in 2005 by Philip Torr and William Clocksin, and is led by Philip Torr. It comprises 8 PhD’s (with vacancies for two more if you know any bright applicants) and 4 post docs, in addition we have some semi regular visitors and joint grants with other universities that account for another 3 PhD’s and 2 postdocs.

The aim of the group is to engage in state of the art research into the mathematical theory of computer vision and artificial intelligence, but to keep the mathematical research relevant to the needs of society. Our research is focused on Bayesian methods, in particular the study of the mathematics underlying Markov Random Fields, combinatorial optimization and Bayesian nets.

The applications come in many forms, and we are involved with several major companies and organizations. With Sony we are working on human computer interaction (via a camera, the “EyeToy”) for the Play Stations 2 and 3, with Sharp we are working on generation of content for 3D displays, with Oxford Metrics Group we are working on computer understanding of films (e.g. what is the shape of objects in the scene etc) in order to make better special effects, we also work on motion capture of humans (and animals) in order to drive computer generated avatars. We work on medical image analysis and on surveillence. We also do collaborative work with Microsoft Research, London, Cambridge and Oxford Universities.
