Dear All,

Due to  many requests, arrived to the Directors of the Course,  to extend the
deadline of  applications,  the deadline has been extended up to
July 1st. There would not be other  extentions.

Best regards

IIASS-International Institute         EMFCSC-Ettore Majorana Foundation
for Advanced Scientifc Studies        and

AIMS

In the  last decade,  ensemble methods have  shown to be  effective in
many  application  domains and  constitute  one  of  the main  current
directions  in Machine  Learning research.   This school  will address
from  a  theoretical  and  empirical  view  point,  several  important
questions  concerning   the  combination  of   Learning  Machines.  In
particular,  different  approaches  to  the problem  which  have  been
proposed  in the  context of  Machine Learning,  Neural  Networks, and
Statistical Pattern Recognition will be discussed. Moreover, a special
stress will  be given  to theoretical and  practical tools  to develop
ensemble  methods  and   evaluate  their  applications  on  real-world
domains, such as Remote Sensing, Bioinformatics and Medical field.

POETIC TOUCH

Vietri (from "Veteri", its ancient  Roman name) sul Mare ("on sea") is
located within  walking distance from Salerno and  marks the beginning
of the Amalfi  coast. Short rides take to  Positano, Sorrento, Pompei,
Herculaneum,  Paestum, Vesuvius,  or by  boat, the  islands  of Capri,
Ischia, and Procida. Velia (the  ancient "Elea" of Zeno and Parmenide)
is a hundred kilometers farther down along the coast.


GENERALITIES


Recently,   driven   by   application   needs,   multiple   classifier
combinations have evolved into  a practical and effective solution for
real-world  pattern recognition  tasks.  The idea  appears in  various
disciplines  (including  Machine  Learning, Neural  Networks,  Pattern
Recognition,  and  Statistics) under  several  names: hybrid  methods,
combining  decisions,  multiple experts,  mixture  of experts,  sensor
fusion and many more.  In  some cases, the combination is motivated by
the  simple observation  that  classifier performance  is not  uniform
across the  input space and  different classifiers excel  in different
regions.   Under  a  Bayesian   framework,  integrating   over  expert
distribution leads naturally to expert combination. The generalization
capabilities of  ensembles of learning machines  have been interpreted
in the  framework of  Statistical Learning Theory  and in  the related
theory of Large Margin Classifiers.

There  are  several  ways  to  use  more  than  one  classifier  in  a
classification  problem.   A first  "averaging"  approach consists  of
generating  multiple hypotheses  from  a single  or multiple  learning
algorithms, and  combining them  through majority voting  or different
linear and  non linear combinations. A  "feature-oriented" approach is
based on different methods to  build ensembles of learning machines by
subdividing the  input space (e.g., random  subspace methods, multiple
sensors  fusion, feature transformation  fusion). "Divide-and-conquer"
approaches isolate the regions in input space on which each classifier
performs  well,  and direct  new  input  accordingly,  or subdivide  a
complex learning problem in  a set of simpler subproblems, recombining
them  using  suitable   decoding  methods.  A  "sequential-resampling"
approach builds multiple classifier systems using bootstrap methods in
order  to  reduce variance  (bagging)  or  jointly  bias and  unbiased
variance (boosting).

There  are fundamental  questions  that  need to  be  addressed for  a
practical  use  of  this   collection  of  approaches:  What  are  the
theoretical tools  to interpret possibly  in a unified  framework this
multiplicity  of  ensemble methods?  What  is  gained  and lost  in  a
combination  of   experts,  when  is  it   preferable  to  alternative
approaches?  What   types  of  data   are  best  suitable   to  expert
combination? What  types of experts are best  suited for combinations?
What are  optimal training methods  for experts which are  expected to
participate in a collective  decision? What combination strategies are
best suited to  a particular problem and to  a particular distribution
of  the data?  What are  the statistical  methods and  the appropriate
benchmark data to evaluate multiclassifier systems?

The school will address some of the above questions from a theoretical
and empirical view  point and will teach students  about this exciting
and very promising field using current  state of the art data sets for
pattern recognition, classification and regression.

The main  goals of the  school are:

1.  Offer an overview of the  main research issues of ensemble methods
from the different and complementary perspectives of Machine Learning,
Neural Networks, Statistics and Pattern Recognition.

2.  Offer  theoretical tools  to analyze  the diverse  approaches, and
critically evaluate their applications.

3. Offer  practical  and theoretical  tools  to  develop new  ensemble
methods and analyze their application on real-world problems.



FORMAT

The  meeting will  follow  the  usual format  of  tutorials and  panel
discussions together  with poster sessions for  contributed papers.  A
demo  lab  with four  Linux  workstations  will  be available  to  the
participants for testing and comparing ensemble methods.

There will be a network of wireless 11MHz connection available so that
students  arriving  with their  laptops  and  an appropriate  wireless
communication card can stay connected while at the meeting area.
