Causal Interpretation and Identification
of Conditional Independence Structures

## Seminar 4 on

CONDITIONAL INDEPENDENCE STRUCTURES AND GRAPHICAL MODELS

September 27 - October 15, 1999

### Organizing Committee:

Milan Studený, *Academy of Sciences of Czech Republic*

Frantisek Matús, *Academy of Sciences of Czech Republic*

**Details**
concerning the starting workshop Conditional Independence Structures
and Graphical Models

### Overview:

The precise description of conditional independence structures and
the one-to-one correspondence of these structures with their visual
or algebraic representation is fundamental to the development and implementation
of algorithms for estimation, testing, etc. This description can be
done using different types of graphs but also using non-graphical tools
based on information theory such as imsets or matroids. The concept
of conditional independence often occurs also in miscellaneous non-probabilistic
calculi for dealing with uncertainty in artificial intelligence. The
purpose of the seminar is to first recall the relatively simple mathematical
tools needed for the axiomatic or graphical characterization of conditional
independence structures (during the starting week's workshop). Then,
researchers will focus on the open problems in this area mentioned in
the original proposal of the seminar or raised by other participants
of the workshop. This type of research can be viewed as the research
for the precise mathematical description of all conditional independence
structures, using both graphs and non-graphical methods.
