Special Session on Interval Uncertainty

Organizers: Martine Ceberio (University of Texas at El Paso),

Christoph Lauter (University of Texas at El Paso), Vladik

Kreinovich (University of Texas at El Paso)

Description: 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techniques and thus use outdated less efficient methods.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 the fuzzy community

by explaining the latest interval techniques and to help the

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 rage

(interval) of possible values -- leading to interval-valued fuzzy

techniques that, in effect, combine both types of uncertainty.

The Joint NAFIPS International Conference on Fuzzy Systems, Soft

Computing and Explainable AI and 10th World Conference on Soft

Computing NAFIPS 2026 will be held in El Paso, Texas, USA, on March

14-16, 2026.

<venue>

In 2025, we had a conference in Banff, Canada, on the Northern side

of Rocky mountains. This year, this conference will be held in the

southmost part of the same mountain range -- in El Paso, Texas.

El Paso is among the ten safest cities in the US, It is a vibrant

border city known for its unique blend of American and Mexican

cultures, affordability, and historic charm. Located in far western

Texas, the "Sun City" offers a high number of sunny days and is

recognized for its beautiful desert landscapes and strong community

spirit.

El Paso is situated at the junction of Texas, New Mexico, and

Mexico, creating a strong binational identity that influences its

food, language (Spanglish is common), and festivals.

The conference venue is the Art, Science, and Technology Building

on the Valle Verde Campus of the El Paso Community College, see

As an international conference in the areas of fuzzy sets and soft

computing, the NAFIPS 2026 conference will bring together

scientists, engineers, students, and practitioners working in fuzzy

logic and related areas to present their recent research

accomplishments. The conference offers a unique platform for the

exchange of ideas, fostering interaction and building

multidisciplinary research linkages.

The topics cover all aspects of fuzzy systems and their applications

including, but not limited to:

• fuzzy sets and fuzzy logic

• mathematical foundations of fuzzy sets and fuzzy systems

• approximate reasoning, fuzzy inference models, and soft computing

• fuzzy decision analysis, decision making, optimization, and design

• fuzzy system architectures and hardware

• fuzzy methods in data analysis, statistics and imprecise probability

• fuzzy databases and information retrieval

• fuzzy pattern recognition and image processing

• fuzzy sets in management science

• fuzzy control and robotics

• possibility theory

• fuzzy sets and logic in ontology, web, and social networks

• fuzzy preference modeling

• fuzzy sets in operations research and manufacturing

• fuzzy database mining and financial forecasting

• fuzzy neural networks

• evolutionary and hybrid systems

• intelligent agents and ambient intelligence

• learning, adaptive, and evolvable fuzzy systems

Deadline for submitting tutorial and special session proposals:

December 1, 2025

Deadline for paper submissions: December 1, 2025

Notification of acceptance: January 15, 2026

Deadline for final versions of accepted papers: February 15, 2026

Conference: March 14-16, 2026

Please submit your tutorial proposals to Marek Reformat, Tutorial

Chair, by email to reformat@ualberta.ca.

Please submit your special session proposals to Fernando Gomide,

Special Session Chair, at gomide@unicamp.br.

Proposals for tutorials and special sessions should include the

title, a short abstract, and the list of organizers (including a

brief listing of their qualifications).

Papers should be submitted via EasyChair, via a link

https://easychair.org/my/conference?conf=nafips2026

If you are submitting to a special session, then when EasyChair asks

you about the paper title, add – in capital letters – the session

title before the title of your paper. For example, if you are

submitting a paper titled "Our great revolutionary ideas for

teaching and learning" to the special session on fuzzy education,

then in the EasyChair slot for paper title write: "FUZZY EDUCATION

Our great revolutionary ideas for teaching and learning". Also, in

addition to submitting your papers to EasyChair, send a copy of your

submission by email to the organizers of the special session.
