Physical systems described by multiple variable and multiple parameter
models having non-linear coupling, frequently occur in the fields of
physics, engineering, technical applications, economy, etc. The
conventional approaches for understanding and predicting the behaviour of
such systems based on analytical techniques can prove to be very
difficult, even at the initial stages of establishing an appropriate
mathematical model. The computational environment used in such an
analytical approach is perhaps too categoric and inflexible in order to
cope with the intricacy and the complexity of the real world physical
systems. It turns out that in dealing with such systems, one has to face a
high degree of uncertainty and tolerate imprecision. Trying to increase
precision can be very costly.

Prof. Lotfi A. Zadeh separates hard computing based on binary logic, crisp
systems, numerical analysis and crisp software from soft computing based
on fuzzy logic, neural nets and probabilistic reasoning. The former has
the characteristics of precision and categoricity and the latter,
approximation and dispositionality. Although in hard computing,
imprecision and uncertainty are undesirable properties, in soft computing
the tolerance for imprecision and uncertainty is exploited to achieve
tractability, lower cost, high Machine Intelligence Quotient (MIQ) and
economy of communication.

The principal constituents of soft computing are

* fuzzy logic (FL)
* artificial neural networks (ANN)
* probabilistic reasoning (PR)

These distinct and yet interrelated methodologies are currently attracting
a great deal of attention and have already found a number of practical
applications ranging from industrial process control, fault diagnosis and
smart appliances to speech recognition and planning under uncertainty. In
this perspective, the principal contribution of fuzzy logic relates to its
provision of a foundation for approximate reasoning, while neural network
theory provides an effective methodology for learning from examples, and
probabilistic reasoning systems furnish computationally effective
techniques for representing and propagating probabilities and beliefs in
complex inference networks.

The planned NATO Advanced Study Institute aims at creating an opportunity
for the engineers and the scientists working in the area of Soft Computing
to come together in an informal atmosphere and to discuss and disseminate
knowledge on the application asp ects of soft computing techniques,
especially in intelligent control systems and mechatronics. Two particular
areas that the institute will put a special emphasis on are (1) how to
achieve a synergetic combination of the three constituents of soft
computing (2) how can such a combination be applied to achieve a high
Machine Intelligence Quotient. The latter will include a critical
investigation of existing applications. Hardware realization possibilities
in the form VLSI chips will also be addressed.


The objectives of ASIs is to disseminate advanced knowledge not yet in
university curricula and foster scientific contacts through high level
teaching courses. An ASI is a post doctoral-level teaching activity
lasting ten days; the meeting normally has 12-15 lecturers and 60-80 ASI
students of different nationalities.

The institute will be held at Hotel Kaya in Titreyengol region (near
Side) of Antalya, Turkey, during August 21 - 31, 1996.

Hotel Kaya is a 5 star hotel on the Mediterranean coast, about 70 km to
the east of Antalya. It has good facilities, such as a 600 meter long
private beach (blue flagged) and a 900 m2 open air pool, sauna and Turkish
Bath (free for hotel guests), disco, amphitheatre, 5 tennis courts (3 are
illuminated), volleyball and basketball fields, watersport facilities,
etc. Rooms are airconditioned and have color TV and minibar.


The total cost of the ASI is $800 including all meals and accommodation
in a double room for 11 nights. Single room supplement is $275 for those not
wishing to share a room.


Applicants should include a current CV with information on academic
qualifications, present nationality, position and place of work and a list
of recent publications. Closing date for applications is 15 March 1996.
Financial support will be available to qualified participants to cover
part of their travel and living expenses. Requests for financial aid must
be specified and justified in the letter of application. Decisions on
admission and financial support will be completed before 30th April 1996.

Two evenings are set aside for contributions by the participants in the
form of poster and short paper presentations. If you would like to
contibute please send a summary. Detailed information and the final program
of the ASI, including the timetable of the lectures will be sent to
succesful applicants, together with the letter of acceptance. Applications
are to be made to:
