[Comp-neuro] Postdoc Position in Modelling Functional Whole Brain Connectivity from fMRI

Postdoc Position in Modelling Functional Whole Brain Connectivity from fMRI

 

DTU Compute, Technical University of Denmark would like to invite applications for a 1-year Post Doc position starting as early as 1 November 2013, with possibility for an extension to two years.


Project Description
Functional magnetic resonance imaging (fMRI) has become a key non-invasive brain imaging technique used to quantify the functional connectivity of the brain. While this imaging modality can be used to derive connectivity estimates inferring the global patterns of functional connectivity at the whole brain level poses an important modeling challenge.

The main goal of this project is to develop and apply tools for the modeling of whole brain functional connectivity based on fMRI data. Key components in the project include fMRI data processing and connectivity analysis using Bayesian modeling approaches.  The project will be based on current work on non-parametric Bayesian models of brain connectivity and will be part of a larger project "Non-parametric Relational Modelling of Functional and Structural Brain Connectivity" funded by the Lundbeck Foundation (2012-2017) aiming at inferring whole brain connectivity from fMRI and diffusion MRI data.

Qualifications
Candidates must have a PhD degree in engineering or equivalent academic qualifications. Experience in multivariate modeling approaches for neuroimaging data in general and fMRI data in particular is a definite advantage. Proficiency programming in Matlab and using fMRI neuroimaging software is also important while the applicant is expected to have a basic knowledge about the human brain. Excellent communication skills in English are essential.

[Comp-neuro] CFP MLINI WS on Machine Learning and Inference in Neuroimaging @ NIPS

MLINI-2013: 3rd Workshop on Machine Learning and Inference in
Neuroimaging at NIPS-2013

https://sites.google.com/site/mlininips2013/

December 9-10, 2013, Lake Tahoe, Nevada, United States

Submission deadline: October 11th, 2013

Workshop Overview:
-----------------------
MLINI is a two day workshop on the topic of machine learning approaches
in
neuroscience and neuroimaging. The goal of the workshop is to pinpoint
the
most pressing issues and common challenges across the fields, and to
sketch
future directions and open questions in the light of novel methodology.
The
workshop aims at providing a forum that joins machine learning,
neuroscience, psychology and psychiatry community, and should facilitate
formulating and discussing the issues at their interface. Motivated by
two
previous workshops, MLINI '11 and MLINI'12, we will center this workshop
around invited talks, and two panel discussions. Triggered by these
discussions, this year we plan to adapt the workshop topics to a less
traditional scope that investigates the role of machine learning in
neuroimaging of both animals and humans, as well as in behavioral models
and psychology.

Open questions and possible topics for contribution will be structured
around the following 4 main topics:

- Machine learning and pattern analysis methodology in neuroimaging
- Functional networks and dynamical models of the brain
- Multi-modal analysis of mental state inference from imaging and/or
behavioral data
- Linking machine learning, neuroimaging and neuroscience

Workshop Format:
--------------------------

In this two-day workshop we will explore perspectives and novel
methodology
at the interface of Machine Learning, Inference, Neuroimaging and
Neuroscience. We aim to bring researchers from machine learning and
neuroscience community together, in order to discuss open questions,
identify the core points for a number of the controversial issues, and
eventually propose approaches to solving those issues.
Each session will be opened by 2-3 invited talks, and an in depth
discussion. This will be followed by original contributions. Original
contributions will also be presented and discussed during a poster
session.
The workshop will end with a panel discussion, during which we will
address
specific questions, and invited speakers will open each segment with a
brief presentation of their opinion.

Paper Submission:
--------------------------
We seek for submission of original (previously unpublished) research
papers. The length of the submitted papers should not exceed 8 pages in
Springer format, excluding the references (LaTeX2e style files are
available on the workshop page).
Submission of previously published work is possible as well, but the
authors are required to mention this explicitly. Previously published
work
can be presented at the workshop, but will not be included into the
workshop proceedings (which are considered peer-reviewed publications of
novel contributions). Moreover, the authors are welcome to present
their
novel work but choose to opt out of the workshop proceedings in case
they
have alternative publication plans.

Important dates:
--------------------------
- October 11, 2013 - paper submission
- October 26, 2012 - notification of acceptance/rejection
- December 9-10, 2013 - Workshop in Lake Tahoe, Nevada US, following
the
NIPS conference

When we make faster decisions, we make more mistakes. When we make slower decisions, we miss more deadlines and we limit the number of decisions we can make. These principles are intuitively obvious and are applicable to decisions in any domain, on any timescale, by any species or automated system. Their resolution defines the speed-accuracy trade-off (SAT). The SAT has long been the subject of experimental and theoretical enquiry. In experiments, subjects make slower, more accurate decisions when motivated to favour accuracy and make faster, less accurate decisions when motivated to favour speed. Computationally, the SAT is well characterized within the framework of bounded integration, where noisy evidence for the alternatives is integrated over time. When the evidence for one of the alternatives reaches a threshold or bound, a choice is made for that alternative. Higher thresholds therefore favour accuracy at the expense of speed. This framework captures a remarkable volume of experimental data, but there is a prominent discrepancy between model fits to behavioural and electrophysiological data. The latter have been taken to suggest that decision thresholds are fixed. If so, then how do we trade speed and accuracy? This question is the focus of intense research interest.

 

A growing number of studies have investigated the neural mechanisms underlying the SAT within the framework of bounded integration, where a convergence of neuroimaging and electrophysiological methods with mathematical and biophysical modelling has provided new perspectives on the mechanisms by which decision times are determined. For example, with a fixed decision threshold, the time spent integrating evidence may be adjusted by modulating the baseline activity of neural integrators, the rate and onset of integration, or the functional connectivity between integrators and other sources of input to thresholding circuitry. Furthermore, there is increasing evidence that the encoding of elapsed time plays a crucial role in the SAT, sometimes referred to as urgency. These and other hypotheses suggest that the conflicting demands of speed and accuracy may be resolved by the differential encoding, readout and integration of evidence. Striking the optimal balance between speed and accuracy in a given context further requires a means to control these mechanisms. In this Research Topic, we welcome articles that characterize or explain the SAT and its optimization according to any experimental factor or neural mechanism, using any experimental or theoretical methodology. While we take temporal integration as a starting point, we encourage articles expressing disagreement with the premises of the bounded integration framework and reporting evidence in favour of alternative explanations of the SAT. All Frontiers article types are welcome, including original research articles, methods articles, hypothesis and theory articles, opinions, perspectives and reviews.

[Comp-neuro] NIPS 2013 Workshop Call For Papers: High-dimensional Statistical Inference in the Brain

   
            NIPS WORKSHOP 2013 CALL FOR PAPERS
       High-dimensional Statistical Inference in the Brain
                Monday, December 9th, 2013
                  Lake Tahoe, Nevada USA
--------
Organizers:
 Mitya Chklovskii
 Alyson Fletcher
 Fritz Sommer
 Ian Stevenson
--------

Overview:
Understanding high-dimensional phenomena is at the heart of many
fundamental questions in neuroscience. How does the brain process
sensory data? How can we model the encoding of the richness of the
inputs, and how do these representations lead to perceptual
capabilities and higher level cognitive function? Similarly, the
brain itself is a vastly complex nonlinear, highly-interconnected
network and neuroscience requires tractable, generalizable models
for these inherently high-dimensional neural systems.

Recent years have seen tremendous progress in high-dimensional
statistics and methods for ``big data" that may shed light on
these fundamental questions. This workshop seeks to leverage these
advances and bring together researchers in mathematics, machine
learning, computer science, statistics and neuroscience to explore
the roles of dimensionality reduction and machine learning in
neuroscience.

Call for Papers
We invite high quality submissions of extended abstracts on topics including,
but not limited to not limited to, the following fundamental questions:

-- How is high-dimensional sensory data encoded in neural systems?
What insights can be gained from statistical methods in dimensionality
reduction including sparse and overcomplete representations?
How do we understand the apparent dimension expansion in higher level
cognitive functions from a machine learning and statistical perspective?

-- What is the relation between perception and high-dimensional statistical
inference? What are suitable statistical models for natural stimuli
in vision and auditory systems?

-- How does the brain learn such statistical models? What are the connections
between unsupervised learning, latent variable methods, online learning
and distributed algorithms? How do such statistical learning methods
relate to and explain experience-driven plasticity and perceptual learning in
neural systems?

-- How can we best build meaningful, generalizable models of the brain with
predictive value? How can machine learning be leveraged toward better design
of functional brain models when data is limited or missing? What role can
graphical models coupled with newer techniques for structured sparsity play
in this dimensionality reduction?

-- What are the roles of statistical inference in the formation and retrieval
of memories in the brain? We wish to invite discussion on the very open
questions of multi-disciplinary interest: for memory storage, how does the
brain decode the strength and pattern of synaptic connections?  Is it
reasonable to conjecture the use of message passing algorithms as a model?

-- Which estimation algorithms can be used for inferring nonlinear and
inter-connected structure of these systems? Can new compressed
sensing techniques be exploited? How can we model and identify
dynamical aspects and temporal responses?

We have invited researchers from a wide range of disciplines in electrical
engineering, psychology, statistics, applied physics, machine learning
and neuroscience with the goals of fostering interdisciplinary insights.  
We hope that active discussions between these groups can set in motion
new collaborations and facilitate future breakthroughs
on fundamental research problems.
