Dear Friends,

We would like to invite you to submit a paper to the IPMU���22 Special Session on Interval Uncertainty.

The 19th International Conference on Information Processing and Management of Uncertainty in Knowledge-Based Systems IPMU 2022 will take place in Milan, July 11-15th, 2022. For more information and submission details, please visit the following website: https://ipmu2022.disco.unimib.it/submission/

The main objectives of this session are as follows:

Interval uncertainty is closely related to fuzzy techniques: indeed, if we want to know how the fuzzy uncertainty of the inputs

propagates through the data processing algorithm, then the usual Zadeh's extension principle is equivalent to processing alpha-cuts (intervals) for each level alpha.

This relation between intervals and fuzzy computations is well known, but often, fuzzy researchers are unaware of the latest most

efficient interval techniques and thus use outdated less efficient methods. One of the objectives of the proposed session is to help

fuzzy community by explaining the latest interval techniques and to help interval community to better understand the related interval computation problems.

Yet another relation between interval and fuzzy techniques is that the traditional fuzzy techniques implicitly assume that experts can describe their degree of certainty in different statements by an exact number. In reality, it is more reasonable to expect experts

to provide only a range (interval) of possible values -- leading to interval-valued fuzzy techniques that, in effect, combine both

types of uncertainty.

Important dates:

- Submission of full papers: Friday, 14 January 2022
- Notification of acceptance: Tuesday, 1 March 2022
- Camera ready submission: Friday, 15 April 2022

We look forward to hearing from you soon.

Best regards,

Martine Ceberio and Vladik Kreinovich
