Goals

To give continuation to previous meetings (Caen June, 2000, Sao Paulo July, 2003, Palermo October, 2005 (cf. http://math.unipa.it/~grim/asi/asi_index.htm)).
Fourth ASI Conference shall provide the opportunity to present:
- new elements of training,
- theoretical advances in non-symmetrical data analysis methods, the Implicative Statistical Analysis (ASI),
- a significant number of real applications in various domains, particularly in the fields of didactics of mathematics, education sciences, psychology, knowledge extraction, economy, biology, etc.

Let us recall that this method of non-symmetrical data analysis allows us to extract and structure knowledge in the form of rules and general rules using a set of data that connects a population of subjects (or objects) with a set of variables. This method stems from the statistical modelling of the quasi-implication: if a given variable or conjunction of variables “a” is noticed among the population, then, in general, so will be variable “b”. The variables referred to can be of various types: binary, modal, numerical, interval, etc. Contrary to the methods of symmetrical analysis based, for instance, on distance or correlation, groups of acquired rules can lead to hypotheses of causality. These groups are structured according to different supplementary approaches (implicative graph, oriented hierarchy). The quantitative determination of subjects or descriptors responsible for these structures is determined by their contribution or their typicality. Finally, the results and their interpretation can be readily visualized by means of the CHIC software (Classification Hiérarchique Implicative and Cohésitive).

Topics of ASI 4

fundamental concepts in ASI: statistical models, types of variables, main and additional variables,
latest and on-going advances, stability of indexes, extension to new types of variables, exception rules, duality individual space vs rule space, metrical structure and space topology in subjects provided by their contribution or their typicality,
critical comparison of ASI steps, models, presentations, and results with those obtained by other methods of data analysis,
practice with CHIC software, expected and actual developments,
applications treated by ASI in comparison to other methods in the fields of didactics, education sciences, psychology, sociology, economy, biology, etc.,
graphical and numerical representations of applied results, ways to help interpreting these results, respective roles and review of variable types, main and additional variables chosen.

Communications

Communications shall be given in Spanish or French or, exceptionally, in Italian or English, and shall concern one or several of the topics listed above. Particular attention shall be given to the justification of the methodological choices made and to the interpretation of results within the framework of the enunciated problems. Oral communications will be subject to a scientific and reading committee review and must be presented in one of these two forms:

poster presented at a special session
oral communication, with a duration still to be defined.

Poster proposals will fit in one page and communication texts will comprise a maximum of 4,000 words or 12 pages. The front page shall state the title of the communication, the names and affiliation of the authors, and an abstract (in Spanish, French, and English) of a maximum of 10 lines. Texts shall be drafted in Word format, Times 10, simple line space, respecting the instructions of the style_WORD_10pt. They are to be submitted before March 17, 2007 in two versions:

an electronic version to rencontreASI4@polytech.univ-nantes.fr
and a paper version to
- Régis GRAS
- 14 avenue de la Chaise
- 35170 BRUZ, France

Invited Keynote Speaker: Professeur Einoshin SUZUKI (Kyushu University, Japan), spécialiste mondialement reconnu en Data Mining, Président d'Honneur en janvier 2007 des Journées "Extraction et Gestion des Connaissances" de Namur.

Title: Découverte des Règles d'Exception Structurées
Summary: In this talk, I would like to explain our efforts for discovery of structured exception rules. In the last decade, we have seen a proliferation of rule discovery research though it is often criticized to result in a huge number of rules most of which are uninteresting. Various evaluation criteria including those based on intensity of implication have been proposed to circumvent this problem. Our approach is different from them because it relies on its pattern representation to discover interesting rules. Statistical criteria as well as practical applications will be also presented.

Schedule:

Submission deadline: March, 17th 2007
Notification to authors: April, 21st 2007
Final version: June, 1st 2007

A collection of papers gathering different forms of contributions will be published in the form of a university journal (with ISSN or ISBN number), and handed out at the beginning of the conference, and shall also be available on-line (on the web).

Program dates and outline

Bearing in mind the needs detected in previous meetings, the fourth edition has been strustured in two consecutive sequences:

A first day of Start, dubbed I, on the fundamentals of SIA and introduction to the implicative method, specially addressed to "young" researchers, and

A second part made of two days, dubbed C, devoted to the presentation of new developments of SIA in the theoretical side and in the applications to several domaines. For the last ones, contributions comparing ASI and other data analysis methods will be privileged.

Thursday, October 18, 2007, 15 hrs - 19 hrs Friday, October 19, 9 hrs - 13 hrs	I	ASI training; practice of data treatment and analysis with the help of CHIC
