REMINDER – CfP: JMLR Special Topic on Kernel and Metric Learning

Multiple Kernel Learning (MKL) has received significant interest in
the machine learning community. It is reaching a point where efficient
systems can be applied out of the box to various application domains,
and several methods have been proposed to go beyond canonical convex
combinations. Concurrently, research in the area of metric learning
has also progressed significantly, and researchers are applying them
to various problems in supervised and unsupervised learning. A common
theme is that one can use data to infer similarities between objects
while simultaneously solving the machine learning task.

A special topic of the Journal of Machine Learning Research will be
devoted to kernel and metric learning with a special emphasis on new
directions and connections between the various related areas; like
learning the kernel, learning metrics, and learning the covariance
function of a Gaussian process. We invite researchers to submit novel
and interesting contributions to this special issue. Further
information can be found at http://doc.ml.tu-berlin.de/jmlr_mkl .

Teleconference seminar on the UTL challenge

Learning Data Representations or Similarity Measures:
The UTL Challenge

Teleconference presentation, by Isabelle Guyon
Thursday January 20, 2011, 8 am PT, 11 am ET, 5 pm CET
Participation instructions http://www.afia-france.org/tiki-index.php?page=GroupeDeLecture110120IG (please review them in advance)

Is it possible to LEARN from unlabeled data Representations of Similarity Measures for use in supervised learning tasks? The Unsupervised and Transfer Learning challenge offers an opportunity to explore this problem of fundamental and practical interest.
Labeling data is not only expensive, it is tedious. When it comes to your own personal data it is also something you do not want to outsource. To help us tagging fast our personal pictures, videos, and documents, we need systems that can learn with very few training examples. The question is whether we can exploit similar data (labeled with different types of labels or completely unlabeled) to improve data preprocessing.
This presentation will outline the setup of the challenge and review the state of the art in unsupervised and transfer learning. Potential challenge participants are invited to attend and ask questions.

Prizes: $6000 + free registrations + travel awards
Dissemination: Workshops at ICML and IJCNN; proceedings in JMLR W&CP.
Deadline phase 1 (unsupervised learning): February 28, 2011
Deadline phase 2 (transfer learning): April 15, 2011

2nd Pascal Challenge on Large Scale Hierarchical Classification

Second Pascal Challenge on
Large Scale Hierarchical Text classification

Web site: http://lshtc.iit.demokritos.gr/
Email: lshtc_info(at)iit.demokritos.gr

Following a successful first edition, we are pleased to announce the 2nd
edition of the Large Scale Hierarchical Text Classification (LSHTC) Pascal
Challenge. The LSHTC Challenge is a hierarchical text classification
competition, using large datasets. This year’s challenge will increase the
scale and the difficulty of the task, using data from Wikipedia
(www.wikipedia.org), in addition to the ODP Web directory data
(www.dmoz.org).

Hierarchies are becoming ever more popular for the organization of text
documents, particularly on the Web. Web directories and Wikipedia are two
examples of such hierarchies. Along with their widespread use, comes the
need for automated classification of new documents to the categories in the
hierarchy. As the size of the hierarchy grows and the number of documents to
be classified increases, a number of interesting machine learning problems
arise. In particular, it is one of the rare situations where data sparsity
remains an issue, despite the vastness of available data: as more documents
become available, more classes are also added to the hierarchy, and there is
a very high imbalance between the classes at different levels of the
hierarchy. Additionally, the statistical dependence of the classes poses
challenges and opportunities for the learning methods.

The challenge consists of three categorization tasks, involving different
documents and category systems. In particular, the largest category system,
based on Wikipedia, contains more than 300,000 categories and 2M documents
for training. The largest category system ever used in the past for
evaluation purposes, to the best of our knowledge, was based on the Yahoo!
Directory and contained 130,000 categories and 500,000 training documents.
In addition to the largest task, two smaller ones, based on Wikipedia and
DMOZ respectively, are included in the challenge. The scale of these is in
the order of the first edition of the challenge. All of the datasets in this
edition are multi-label. Particularly in the two datasets that are based on
Wikipedia, each document is assigned on average to 3.2 and 4.6 categories
respectively. Furthermore, the hierarchies are no longer simple tree
structures, as both documents and subcategories are allowed to belong to
more than one other category. More information regarding the tasks and the
challenge rules can be found at the challenge’s Web site; follow the “Tasks,
Rules and Guidelines” link.

As in the first edition, participants will be able to smoothly and
continuously submit runs, in order to improve their systems. This year we
also plan a two-stage evaluation of the participating methods: one measuring
classification performance and one for computational performance. It is
important to measure both, as they are dependent. The results will be
included in a final report about the challenge and we also aim at organizing
a special ECML’11 workshop.

In order to register for the challenge and gain access to the datasets you
must have an account at the challenge Web site.

THREE TENURE TRACK OR TENURED POSITIONS IN INFORMATION AND COMPUTER SCIENCE

Aalto University (http://aalto.fi/en/) is a new university created in
2010 from the merger of the Helsinki University of Technology TKK, the
Helsinki School of Economics, and the University of Art and Design
Helsinki. The University’s cornerstones are its strengths in education
and research, with 20,000 basic degree and graduate students, and a
staff of 4,500 of which 300 are professors.

The positions are located at the University’s Department of Information
and Computer Science (http://ics.tkk.fi/en/), and are open to outstanding
individuals who hold a doctorate and have excellent potential for
a successful scientific career. On the basis of their experience and
competence, applicants will be placed at one of the four levels of
the tenure track system: Assistant Professor (1), Assistant Professor (2),
Associate Professor, and (Full) Professor. Successful candidates at
the two first-mentioned levels would be appointed for a fixed term,
whilst appointments at the Associate Professor level are either
permanent (tenured) or for a fixed term. Full Professor positions are
always tenured.

The focus of the Information and Computer Science Department’s
research and teaching activity is on advanced computational methods
for modelling, analysing, and solving complex tasks in technology and
science. The research aims at the development of fundamental computer
science methods for the analysis of large and high-dimensional data
sets, and for the modelling and design of complex software, networking
and other computational systems.

– In the recent Research Assessment Exercise covering all the 46
academic units of Aalto University, the Department was identified as
one of the select two highest-ranking performers (RAE score 24/25)
and as “one of the top five centres in the world in their research
area”. The full report “Striving for Excellence, Aalto University
Research Assessment Exercise 2009” is available at
http://aalto.fi/en/research/rae/.

– The present call for applications covers all areas of information
and computer science compatible with the Department’s research and
teaching mission indicated above. Special consideration will be
given to candidates with research fields complementing and
supporting the current strong areas of the Department. A joint
appointment with the Helsinki Institute for Information Technology
HIIT (http://hiit.fi/) can be negotiated.

The closing date of the call is 4 February 2011. Should there be a
lack of eligible outstanding applicants, the application period may
be extended. While all applicants who have submitted an application
by the deadline will be appropriately considered, Aalto University
reserves the right to consider also other candidates for the announced
