Postdoctoral Research Fellow roles - EPSRC Centre for Predictive Modelling in Healthcare, University of Exeter
by Purcell, Sarah 13 Aug '18

13 Aug '18

2 Postdoctoral Research Fellow roles - EPSRC Centre for Predictive Modelling in Healthcare University of Exeter, UK Two Research Fellows are required to support the EPSRC Centre for Predictive Modelling in Healthcare<http://emps.exeter.ac.uk/mathematics/research/pmh/> (CPMH). The roles are available from 01 October 2018, or a mutually agreeable date soon thereafter, for a period of up to 24 months. The CPMH is a £2M award which brings together outstanding scientists from mathematics, statistics, computer science and our medical school. With an additional £7M in research funding, the interface between mathematics, computer science and healthcare is one of the most rapidly expanding areas within the University. The Centre forms part of the Quantitative Biology and Medicine Initiative, which currently consists of 15 PDRAs, 9 fellowship holders, and 10 PhD students. The successful candidates are expected to focus on one of the following areas, depending on their interests and background: (a) Transient dynamics of networks with multiple time scales: there are significant mathematical challenges from disease modelling that require the development of new techniques to understand transient behaviour in multiple timescale systems, especially for systems where there is not a simple factorization into fast and slow subsystems. (b) Numerical investigation of models of cardiac diseases: involving multi-scale excitable and transient dynamics, with a focus on re-entrant arrhythmias specifically concerning development and improvements of antiarrhythmia pacing, low-voltage defibrillation and catheter ablation. [In partnership with cardiologists at the RD&E Hospital, Exeter]. (c) Mathematical modelling and analysis of EEG in dementia: EEG analysis has shown promise in differentiating people with dementia from healthy older adults, and therefore could provide indications for early diagnosis. We will use mathematical models to better understand why differences in EEG occur and combine models and analysis to build improved diagnostic markers. [In partnership with colleagues in Bath, Bristol & Reading]. (d) Mathematical modelling and analysis of polygenic disease: conditions such as diabetes and dementia depend on the simultaneous presence of several genes; they are not inherited as simply as single-gene diseases and therefore require the development of new mathematical approaches to improve diagnosis via e.g. the interpretation and uncertainty quantification of proportions of patients in large data sets (e.g. UK Biobank) using genetic risk scores. [In partnership with diabetologists and neurologists from the Medical School]. For full details please see the job advert<https://www.jobs.ac.uk/job/BLL261/postdoctoral-research-fellow/>. Application deadline: 20 August 2018. For further information please contact Centre Manager Sarah Purcell, email S.Purcell(a)exeter.ac.uk<mailto:S.Purcell@exeter.ac.uk> or telephone 01392 726447.

Extension Call for Abstracts: New Deadline August 31 - Cognitive Computing - Merging Concepts with Hardware
by Prof. Dr. Gordon Pipa 06 Aug '18

06 Aug '18

Upon demand and the holiday period in August we extend the Deadline for submissions of abstracts until the end of August. New Deadline for Abstract submission: August 31 Call for participation and contributions: COGNITIVE COMPUTING: MERGING CONCEPTS WITH HARDWARE December 18-20, 2018, Hannover, Germany http://www.cognitive-comp.org/ ** An interdisciplinary networking event / scientific conference ** We would like to draw your attention to an upcoming scientific community event. The aim of this conference is to work towards a general, productive, and rigorous theory of “computing” in non-digital, nonlinear physical substrates. Biological brains and unconventional computing machines would become understandable as different instantiations of the same underlying principles. Three scientific communities, namely - cognitive and computational neurosciences, - theory of computation, and - nonlinear materials, devices and systems have since long been exploring diverse facets of such principles of non-digital computing. But differences in terminology, discipline-specific objectives and a scattered spectrum of formal methods have handicapped cross-fertilization. Everything in this conference is geared toward stimulating linkages between these fields: - single-track with few but rather long oral presentations, - long break and poster session times for person-to-person interaction, - keynote and plenary speakers with interdisciplinary renown, - a limited (200) number of participants, - a splendid setting in the Castle of Herrenhausen, a heritage of the Kings of Hannover, with adjoining hectares of classical French gardening. Invited and confirmed speakers: - Kwabena Boahen, Stanford University - Joanna J. Bryson, Univ. of Bath and Princeton University - Chris Eliasmith, University of Waterloo - Edward A. Lee, UC Berkeley - Demetri Psaltis, EPFL Lausanne - Pieter Roelfsema, Vrije Universiteit Amsterdam & Netherlands Institute for Neuroscience - Susan Stepney, University of York - Ipke Wachsmuth, University of Bielefeld - David Wolpert, Santa Fe Institute We solicit the submission of 2-page abstracts, with themes oriented toward our five topical sessions: - applications of unconventional computing systems, - theoretical concepts and mathematical foundations, - neuromorphic hardware, - novel physical substrates, - guides from neuroscience for computing technologies. In addition to latest specific achievements, we specifically encourage survey / introductory / didactic contributions. Detailed information can be found on http://www.cognitive-comp.org/ and in the Call for Abstracts that is posted there. Timelines: - Abstract submission: July 31 - Notification of acceptance: September 30 - Final abstract for online publication: October 31 Registration fees: - Students (incl. PhD students): 150 Euro - Others (academic): 300 Euro - Industry: 900 Euro Contributors of accepted oral presentations will be exempted from fees and will receive travel refunding. The event was made possible by the generous support from the Volkswagen Foundation, Germany’s largest private organization for the advancement of scientific research. The organizers: - Daniel Brunner (photonics, neuromorphic architectures; CNRS / University of Burgundy - Franche-Comté) - Herbert Jaeger (machine learning, nonlinear dynamics; Jacobs University Bremen) - Stuart Parkin (nano systems, quantum electronic materials; Max-Planck-Institute for Microstructure Physics, Halle) - Gordon Pipa (neuroinformatics and cognitive computing; University of Osnabrück)

A biologically motivated and more powerful alternative to locality-sensitive hashing
by Rod Rinkus 02 Aug '18

02 Aug '18

I believe this community will be interested in a new downloadable Java app that I 've just made available on my web site (on this page <http://www.sparsey.com/CSA_explainer_app_page.html>), which describes an alternative, biologically motivated/plausible, way to achieve the goals of locality-sensitive hashing (LSH). This alternative model, called Sparsey, achieves a more graded notion of similarity preservation than LSH, and has many other advantages as well. Sparsey has a natural correspondence to the brain's cortex, centering on the idea that all items of information are stored as sparse distributed codes (SDCs), a.k.a., cell assemblies, in superposition in mesoscale cortical modules, e.g., macrocolumns (though other structures, e.g., mushroom bodies, are also candidates). Briefly, Sparsey preserves similarity from input space to SDR code space (measured as intersection size) as follows. - The process of choosing an SDC takes the form of Q independent softmax choices, one in each of the Q WTA competitive modules (CMs) that comprise the SDR coding field. - The familiarity (inverse novelty) of the input, denoted "G", which is in [0,1], is computed. This is an extremely simple computation. - The amount of noise in those Q softmax choice processes is modulated as a function of G. Basically, the softmax is over the distribution of input summations of the competing cells (in a given CM), but we use G to modulate (i.e. sharpen vs. flatten) those distributions. - When G is near 1 (perfect familiarity), the distributions are greatly sharpened, causing the expected number of CMs in which the cell with the highest input summation wins (and thus, the expected intersection of the resulting SDR with the closest matching previously stored SDR) to increase towards Q. When G is near 0 (completely novel), the distributions are flattened, causing the expected number of CMs in which the cell with max input summation wins (and thus, the expected intersection of the resulting SDR with the closest matching previously stored SDR) to decrease towards chance. In other words, this G-based modulation of the distributions, which can be viewed as varying the amount of noise in the choice process, achieves similarity preservation. I encourage members of this community to explore the app to understand this simple and more powerful alternative to LSH. I welcome your feedback.
