The 3^rd International Conference on Artificial Intelligence, Big Data and Algorithms (CAIBDA 2023) was held as a hybrid conference in Zhengzhou, China, from 16-18 June 2023. The purpose of CAIBDA 2023 was to discuss the present status and future perspectives of artificial intelligence, big data and algorithms. The following topics were selected in order to cover most of the scientific program and highlight an area where new ideas have emerged over recent years:

(1) Artificial Intelligence Tools and Applications;

(2) Intelligent Estimation and Classification;

(3) Representation Formats for Multimedia Big Data;

(4) High-performance Computing;

(5) Mathematical and Computer Modeling, etc.

Around 200 participants attended the conference. In addition to the keynote speeches, many presentations were selected from contributed papers, including oral and poster sessions. These proceedings contains those papers presented as keynote and selected talks, together with other contributions.

Conference participants discussed a wide range of issues related to the theoretical and computational aspects of research in artificial intelligence, big data and algorithms. In addition, thanks to the participation of leaders from a number of important projects, the conference provided a comprehensive overview of this fascinating field and of future scenarios. Professor Meng Zheng (Chinese Academy of Sciences, China) delivered a keynote speech, and shared his own research experience and professional views with the report ‘Design and Optimization Methods in Wireless Networks for Industrial Automation’. He first introduced representative fundamental results on wireless networks for process automation, including the topology design for large-scale and low-overhead networking and cognitive networking protocols. He also presented work on wireless networks for factory automation, including the topology design for dense and mobile networking and for on-demand reliable retransmission and resource allocation schemes for heterogeneous coexisting traffic. Finally, he discussed the applications of industrial wireless networks in industrial automation systems.

We would like to take this opportunity to thank our host institutions, sponsors, and the many people whose work made this conference possible, and express our gratitude to the members of the International Technical Program Committee and Organizing Committee for their efforts, which made this conference a success. In particular, we would like to thank the editors and other colleagues at IOS Press, publishers of the series Frontiers in Artificial Intelligence and Applications, for their patience and kind assistance in publishing this volume.
