It is our great pleasure to have you at the 5th International Conference on Artificial Intelligence Technologies and Applications (ICAITA 2023), which took place in Changchun, China from June 30th to July 2nd, 2023 (hybrid conference). The Conference was hosted by Changchun University of Science and Technology and successfully held, receiving unanimous praise from various experts and scholars all over the world.

ICAITA 2023 existed as an international forum for academic communications between experts and scholars in the field of artificial intelligence. It promoted the research and developmental activities in related fields and scientific information interchange among all the participants, establishing research connections for them to find global partners for potential collaboration.

We had about 300 participations both as speakers and participants, including senior experts, research talents, and young scholars from enterprises, research institutes, and universities worldwide. During the keynote speech part, each keynote speaker was given 30–40 minutes for keynote speech. Among them, Professor Philippe Fournier-Viger from Shenzhen University, China performed a keynote speech on Advances and Challenges for the Automatic Discovery of Interesting Patterns in Data. First, he briefly reviewed early studies on designing algorithms for identifying frequent patterns. Then, he presented an overview of recent challenges and advances to identify other types of interesting patterns in more complex data. Topics that were discussed include high utility patterns, locally interesting patterns, and periodic patterns. Lastly, the SPMF open-source software was mentioned and opportunities related to the combination of pattern mining algorithms with traditional artificial intelligence techniques for intelligent systems were discussed. These experts shared remarkable academic achievements in edge computing, computer communication, machine learning applications, and AI applications, and discussed critical challenges and research directions within these domains, triggering heated discussion during the Conference and even in the break.

After months of careful preparation and hard work, the Proceedings of ICAITA 2023, having been checked through rigorous review and processes to meet the requirements of publication, are published. These papers feature but are not limited to the following topics: Artificial Neural Networks, Computational Theories of Learning, Intelligent System Architectures, Pervasive Computing and Ambient Intelligence, Fuzzy Logic and Methods.

We would like to express our gratitude to the organizers, keynote speakers and all the participants of ICAITA 2023, for their fruitful work and contribution to the success of the Conference. We are thankful to all the reviewers for providing constructive criticisms, stimulated comments and suggestions to the authors. Particularly, our special thanks go to IOS Press, for the endeavor of all its colleagues in publishing this volume. May this event be a spark that ignites many more new inventions in the fields related to artificial intelligence technologies and applications!
