About CDEF

Building on the success of the past three years of the Special Session on Applied Informatics in Finance and Economics (AIFE) and continuous International Conference on Computational and Data Sciences in Economics and Finance (CDEF), we are pleased to announce that CDEF will be held as an international conference also in 2026. As in the previous years, it will be part of the IIAI AAI Congress and the proceedings will primarily be published by IEEE (please refer to previous programs: 2023, 2024, 2025). CDEF will mark its fourth annual conference. We look forward to your submissions/contributions.

Aims and Scope

With the recent development of informatics and AI technologies, they now play a key role in financial markets and economics. For example, for analyzing a large amount of financial information, computational informatics is necessary to handle them. Moreover, artificial market simulations, computational economics, natural language processing including large language models for finance and economics, and deep learning applications for many financial-related and economics-related challenges are also popular. More recently, alternative data exploration for wider informatics approaches is also gaining popularity in the financial and economic industries. Those new technologies have been developed not only by academic researchers but also by market participants. For more development, the collaboration of many participants having various backgrounds is now necessary. In this session, we aim to give them the specialized opportunity to gather and discuss new challenges in finance and economics. In organizing the second edition of the special session following the last year, we highly appreciate paper submissions from wider financial and economic topics and participation from the wider area, including academic and industrial areas.
