Abstract
Multi-view learning is a natural, yet non-standard new problem
setting; it describes the problem of learning from data
represented by multiple independent sets of features.
A typical example is learning to classify web pages
by either the words on the page or the words
contained in anchor texts of links to the page.
Multi-view learning methods have been studied by
Yarowsky (1995)
and
Blum and Mitchell (1998),
who noticed that having multiple representations
can improve classification performance
when in addition to labeled examples, many unlabeled examples are
available.
A recent result by
Abney (2002)
suggests that there
may be an underlying principle which gives rise to a family of new
methods: The disagreement rate of two independent hypotheses
upper-bounds the error rate of either hypothesis. By minimizing the
disagreement rate on unlabeled data, the error rate can be minimized.
In the last 2-3 years, several new supervised and unsupervised methods have
been proposed which
appear to utilize this consensus maximization principle in one way or
another. However, in many cases the contributors are not to the full
extent aware of the relationships between their methods and a possible
common underlying principle.
The workshop aims at bringing together researchers who are working on
learning problems with multiply represented instances and consensus
maximizing learning methods; our goals are to make the intrinsic
structure of this field more clearly visible and to bring
this interesting and rapidly developing area to the attention of
additional researchers.
Topics of the workshop include
- analysis of algorithms: co-training, co-EM, co-EMT, ...
- active and semi-supervised learning
- multi-view clustering and classification
- novel learning tasks (interpretability, constraints, ...)
- independence of views: quantification and relevance
- text, web, and other applications
- hierarchical, partitioning, spatial, spectral clustering
- theoretical analyses
- relation to other fields of learning (e.g., boosting)
- consensus maximization principle
- generative and discriminative models
