The 2025 21th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD 2025) will be held from 26-28 July 2025 in Hohhot, China.Hohhot is a phonetic translation from Mongolian, meaning "the city of blue", and is the capital of Inner Mongolia Autonomous Region, known as "the Milk Capital of China", and has been honored with titles such as "a national model city for ethnic unity and progress", "a national ecological civilization city", "a national forest city", "an excellent tourist city in China", "a national historical and cultural city", "one of the top ten most happy cities in China", "a national model city for military-civilian integration", and "a Chinese city for health and wellness tourism".

As with the past ICNC-FSKD conferences, all papers in conference proceedings will be submitted to EI Compendex, Scopus, and ISTP (ISI Proceedings). ICNC-FSKD 2005-2024 have all been indexed in EI Compendex, etc.

ICNC-FSKD is a premier international forum for scientists and researchers to present the state of the art of data mining and intelligent methods inspired from nature, particularly biological, linguistic, and physical systems, with applications to computers, circuits, systems, control, communications, and more. This is an exciting and interdisciplinary area in which a wide range of theory and methodologies are being investigated and developed to tackle complex and challenging problems. The registration fee includes proceedings, lunches, dinners, banquet, coffee breaks, and all technical sessions.

Prospective authors are invited to submit manuscripts written in English. All submissions will be peer-reviewed by experts in the field based on originality, significance, quality and clarity. Authors should use the Latex style files or MS-Word templates obtained from the conference site to format their papers. Authors should submit PDF files of their manuscripts via the online submission system. Submissions imply that the papers have not been submitted elsewhere and will not be submitted elsewhere for publications before the review decisions of this conference.
