Papers related to interval-valued and fuzzy-valued probabilities are always welcome at this series of fuzzy conferences

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is well known, but often, fuzzy researchers are unaware of the latest most efficient interval techniques and thus use outdated less efficient methods.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 https://www.epcc.edu/Contact/about-the-campuses

<Aims and Scope>

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.

<Topics>

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

<How to submit>

Please submit your tutorial proposals to Marek Reformat, Tutorial Chair, by email to reformat@ualberta.ca<mailto:reformat@ualberta.ca>.

Please submit your special session proposals to Fernando Gomide, Special Session Chair, at gomide@unicamp.br<mailto: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.
