Subject: Implicit Filtering Software
My implicit filtering code for derivative-free optimization in matlab
now lives at
http://www4.ncsu.edu/~ctk/imfil.html
The package includes the code, several worked examples, and a
manual. The code is connected to my upcoming SIAM book on implicit
filtering.
Implicit filtering is a hybrid of a projected quasi-Newton or
Gauss-Newton algorithm for bound constrained optimization and
nonlinear least squares problems and a deterministic grid-based search
algorithm. The gradients for the quasi-Newton method and the Jacobians
for the Gauss-Newton iteration are approximated with finite
differences, and the difference increment varies as the optimization
progresses. The points on the difference stencil are also used to
guide a direct search.
Have fun.

Subject: Workshop, Manifold Learning, Germany, May 2011
Workshop on Manifold Learning
The workshop will be held in the week of May 30 - June 3, 2011 in
Bonn, Germany. It is part of the Trimester Program on Analysis and
Numerics for High Dimensional Problems at the Hausdorff Research
Institute for Mathematics (HIM).
http://www.him.uni-bonn.de/high-dimensional-problems-workshop2
http://www.him.uni-bonn.de/high-dimensional-problems
In the field of manifold learning, non-linear methodologies are
investigated to efficiently describe high-dimensional data by lower
dimensional structures. The research is motivated by the observation
made in many data driven research fields that a rich structure is
present in the application data which can and needs to be exploited
for an efficient representation.
In recent years several new machine learning algorithms were
introduced which allow such a nonlinear dimension reduction. They aim
to exploit local structure and estimations of the intrinsic geometry,
dimension, or topology. Theoretical insights from topology allowed
new methods for dimensionality estimation. New regularisation
approaches for classification and regression which take the geometry
into account are also closely related to manifold learning.
The workshop aims to bring together researchers interested in manifold
learning and dimension reduction. Due to the diverse nature of the
field this includes, but is not limited to, people from machine
learning, numerical mathematics, linear algebra, topology, geometry,
or statistics.

Subject: Variational Multiscale Methods, Glasgow, Jun 2011
A workshop entitled 'Variational Multiscale Methods - VMS2011' will
take place from 9 to 10 June 2011 at the University of Strathclyde,
Glasgow. This meeting aims to discuss recent progress in the field of
variational multi-scale methods, both as multiscale methods and on its
relation to stabilized finite element methods, along with their
connection to other solution strategies, as DG methods. Also, the
applications of the resulting methods to more challenging situations,
as turbulence modeling, flow through porous media, visco-elastic
flows, as well as implementation issues are also very welcome. It will
thus provide an excellent introduction to the subject area for younger
researchers. In addition, time will be made available for discussions
and to allow the formation of new collaborations.

The Institute of Mathematics and its Applications
Computational Neuroscience
University of Plymouth, UK, 5-7 September 2011
The complexity, apparent stochasticity, and sheer scale of the
circuitry of the brain and the behaviour it expresses may well pose
unique challenges to our capacity for mathematical description. Real
progress will depend on maintaining strong links between the
mathematical and empirical communities. As such, our goal in this
meeting is to bring together mathematicians and neuroscientists with a
shared focus on how mathematical tools can be brought to bear on
understanding the function of the system.
Submissions are invited to address any of the following:
* model-driven analyses of neural and behavioural data at a range of
different scales, that reveal essential aspects of the processing
function (s) of the system.
* mathematical analysis of the computational function of the nervous
system, with particular emphasis on how this analysis informs our
understanding of neural circuitry.
* mathematical analysis of the structure of neural components and
circuits, with particular emphasis on how this structure underlies
neural computations.
Papers will be accepted for the conference based on a 100-200 word
abstract. Abstracts should be submitted by 3 June 2011 either online
at http://online.ima.org.uk/ or by email to conferences@ima.org.uk

Subject: Postdoc Position in Mathematical Biology, BCAM
We are currently looking for a post-doctoral researcher, who may be
interested in joining our research line MBMS (Mathematical Biology and
Molecular Simulation) which is one of the research lines of BCAM
(Basque Center For Applied Mathematics) (www.bcamath.org), located in
Bilbao, Spain.
http://www.bcamath.org/public_research/ctrl_research.php?accion=3DMBMS&vist=
a=3Dgeneral
MBMS has a strong interest in the area of mathematical modelling and
analysis of structured population dynamics with applications in cell
biology, ecology and epidemiology.
The mathematical formulation of the population equations includes
integral equations, in particular renewal equations, and delay
differential equations (DDE). We are trying to adapt the usual
methods of linearization and bifurcation analysis using characteristic
equations to the above types of equations. To compute from the
characteristic equations stability boundaries in two-parameter space,
we are developing numerical methods, which are a combination of
numerical curve continuation and ODE solvers.
Currently, we are working on several projects in cell population
dynamics, in the fields of stem cell maturation, tumour dynamics and
quiescence. The projects involve a collaboration with a laboratory of
the Biosciences research center CIC BioGUNE.
It would be desirable of the candidate to have an interest to become
involved into our projects and to fit into one of the following
profiles:
(1) understanding of dynamical systems and their computational
implementation, in particular, programming skills and experience in
Matlab, preferably also C/C++.
(2) background in infinite dimensional dynamical systems, e.g.,
integral equations, delay differential equations and/or experience or
interest in state-dependent delay,
Researchers who are interested in this project are encouraged to
contact informally Philipp Getto at getto@bcamath.org
