Information for Authors


You are cordially invited to participate in 2021 North American Fuzzy Information Processing Society Annual Conference to be held at Purdue University, West Lafayette, IN, USA on June 7-9, 2021. 

The aim of NAFIPS 2021 is to bring together researchers, engineers, and practitioners working in fuzzy logic and related areas to present their latest achievements and innovations. The meeting offers a unique platform for the exchange of ideas, discussion of thought-provoking developments and challenges, and consideration of potential future directions.

The scope of this conference covers all aspects of theory and applications in fuzzy systems, soft computing methods, and fuzzy information processing.


Conference Format and Presentation Instructions

The conference will take place in an on-line setting. There will be no in-person events due to the ongoing COVID-19 concerns. 

Talks will be held via Zoom, live.  If you are concerned about your connection, please prerecord your presentation and send it to Julia Rayz ( as your backup alternative. Please make sure you have Zoom version 5.3 or above to allow for your seamless transition between parallel sessions (please click the link for Zoom instructions). Student volunteers will be available in the main room as well as parallel sessions to help with the technology. 

The conference will also use SpatialChat application for social interaction between people outside of the sessions to have an experience similar to in-person conferences (instructions for SpatialChat can be found here).

There will be a training session on June 6th at 2p EST for participants that would like to try parallel session functionality. 




Authors should prepare a manuscript of no more than 12 pages, including results, figures, and references, using the Springer Verlag contributed book style in LaTeX (SVMult) or MS Word.

Authors should submit a PDF file through the EasyChair submission link. If accepted, the final version of the submission will include either the LaTeX source or MS Word, with all figures, and the generated PDF.

If the manuscript is meant for a special session, the title you enter into the EasyChair system must have the name of the special session at the beginning (session_title: paper_title). For instance, if you are submitting a paper entitled “An Image Processing Algorithm to Detect Defects in Optical Fibers” to a special session on “Image and Signal Processing”, the title you enter into the EasyChair system should be: “IMAGE AND SIGNAL PROCESSING: An Image Processing Algorithm to Detect Defects in Optical Fibers”. In addition, please submit your contribution to the organizer of the Special Session. 

Student papers

We strongly encourage students to submit papers under the mentorship of their faculty advisors. Special best paper awards will be presented at the conference banquet to recognize the accomplishments of students. To qualify, a student or a group of students must be the primary author(s) of the paper. The papers will be judged based on both manuscript content and presentation quality.




Please follow the link for the registration.  

Registration Fees:

Student registration: $75

Regular registration: $200
