Call for participation: Challenge on Robust activity recognition @ SMC

Call for participation

ACTIVITY RECOGNITION CHALLENGE
http://www.opportunity-project.eu/challenge

Human activity recognition can be used to devise assistants that
provide proactive support by exploiting the knowledge of the user’s
context, determined from sensors located on-body. Notwithstanding the
large amount of research endeavours on this field, the comparison of
different approaches is often not possible due to the lack of common
benchmarking tools and datasets that allow for replicable and fair
testing procedures across several research groups.

We intend to address this issue by setting up a
challenge on activity recognition addressing key questions in
activity recognition such as classification based on multimodal
recordings, activity spotting and robustness to noise. To this end we
provide a benchmark database of daily activities recorded in a sensor
rich environment.

Prizes will be awarded to participants that achieve the best
performance, and the overall lessons and results obtained from this
challenge will be presented at the associated workshop at the IEEE
Conference on Systems, Man and Cybernetics 2011. Moreover, we are
currently arranging the future publication of selected contributions in
a top journal in the field.

Three Post-Doctoral Research Assistantships and PhD Studentships

The UK-EPSRC funded project “Learning to Recognise Dynamic Visual Content from Broadcast Footage” is a collaboration between the University of Surrey (Prof Richard Bowden), the University of Oxford (Prof Andrew Zisserman) and the University of Leeds (Dr Mark Everingham) with research staff appointed at each institution.

The aim of the proposed research is to develop computer vision and machine learning methods for understanding dynamic visual content. These methods will support systems capable of automatically recognising from video the actions of people, and their interactions with others, objects and the environment. There are two demonstration activities in the areas of Sign Language Recognition and that of more general broadcast content. The project will develop new approaches to weakly supervised learning from subtitles and transcripts.

The project is funded for four years and each institution will host one RA and there are also funded PhD positions available, however all parties will work closely together to fulfil the project objectives.

Potential candidates for the postdoctoral position should hold a PhD in a related discipline with a proven track record in terms of international publications. You should have a research background in computer vision or machine learning. Experience in areas such as human detection, tracking and Sign Language, gesture or activity recognition would also be an advantage. You should have the technical skills necessary to create new and exploit existing software tools for video analysis.

Project Description :

Graphical models are probabilistic models where dependencies between
observable and latent random variables are represented by a graph. HMM are
simple kinds of graphical models. Tree-structured graphical models extend
the expressivity of HMM and are widely used in bio-informatics and Natural
Language Processing. The question of the inference of parameters of a
tree-structured graphical model is not completely solved, even when the
tree topology of the underlying model is unique and supposed to be known.
The inference of the topology of the model from samples is still an open
question.

Recent learning methods rely on algebraic and geometrical properties of
these models and reduce the inference of parameters topology of the models
to spectral computations on matrices. Indeed, tree-structured graphical
models can be seen as particular rational tree series which can be
described by means of natural algebraic operators.

At first, the student will study the link between two formalisms,
tree-structured graphical models and tree rational stochastic languages,
and compare the algorithms described in the references below. Then, she/he
will study the question of the identifiability of tree-structured
graphical models from samples and explore the possibility of developing a
semi-supervised-like learning algorithm, when some topology-samples pairs
are available. Two extensions could be considered : kernelization and
extension to more general graphical models, for example based on regular
graphs.

Data Mining School in Maastricht, The Netherlands

9-th Summer School on Dat Mining, Maastricht, The Netherlands
http://www.unimaas.nl/datamining/
An intensive 4-day introduction to methods and applications

Department of Knowledge Engineering, Maastricht University,
Maastricht, The Netherlands
August 29 – September 1, 2011

Introduction
Most business organizations collect terabytes of data about business
processes and resources. Usually these data provide just “facts and
figures”, not knowledge that can be used to understand and eventually
re-engineer business processes and resources. Scientific community in
academia and business have addressed this problem in the last 20 years
by developing a new applied field of study known as data mining.
In practice data mining is a process of extracting implicit,
previously unknown, and potentially useful knowledge from data. It
employs techniques from statistics, artificial intelligence, and
computer science. Data mining has been successfully applied for
acquiring new knowledge in many domains (like Business, Medicine,
Biology, Economics, Military, etc.). As a result most business
organizations need urgently data-mining specialists, and this is
the point where this school comes to help.

Description
The school curricullum is well balanced between theory and practice.
Each lecture is accompanied by a lab in which participants experiment
with the techniques introduced in the lecture. The lab tool is Weka, one
of the most advanced data-mining environments. A number of real data
sets will be analysed and discussed. In the end of the school
participants develop their own ability to apply data-mining techniques
for business and research purposes.

Tools
The school focuses on techniques with a direct practical use.
A step-by-step introduction to powerful (freeware) data-mining tools
will enable you to achieve specific skills, autonomy and hands-on
experience. A number of real data sets will be analysed and discussed.
In the end of the school you will have your own ability to apply data-
mining techniques for research purposes and business purposes.

Content
The school will cover the topics listed below.
– The Knowledge Discovery Process
– Data Preparation
– Basic Techniques for Data Mining:
+ Decision-Tree Induction
+ Rule Induction
+ Instance-Based Learning
+ Bayesian Learning
+ Support Vector Machines
+ Regression Techniques
+ Clustering Techniques
+ Association Rules
– Tools for Data Mining
– How to Interpret and Evaluate Data-Mining Results

Intended Audience
This school is intended for four groups of data-mining beginners:
students, scientists, engineers, and experts in specific fields who need
to apply data-mining techniques to their scientific research, business
management, or other related applications.

Prerequisites
The school does not require any background in databases, statistics,
artificial intelligence, or machine learning. A general background in
science is sufficient as is a high degree of enthusiasm for new
scientific approaches.

Certificate
Upon request a certificate of full participation will be provided after
the school.
