Preface

2022 4th International Conference on Artificial Intelligence and Computer Science (AICS2022) has been held successfully on July 30-31, 2022. Due to the COVID-19 pandemic around the world, and with the strict travelling rules in China, it is still difficult to take international travel for our attendees abroad. Therefore, AICS2022 was held both in physical (Beijing, China) and online (Zoom). About 80 attendees have participated in the conference. The conference was divided into three parts: five keynote speeches in the first day, each with 45min, and 18 oral presentations followed in the first afternoon and the second day, each with 15min. Besides, 20 e-posters have been presented in the conference website. The session chairs and keynote speakers have worked together to selected the best oral presentation and poster presentation. This year, AICS2022 has attracted about 90 submissions, and 38 of them are accepted to be included in this collection. The process of evaluation and peer-review has last for about 6 months, with over 50 TPC members and reviewers involved in. We would like to express our sincere gratitude to all experts for their professional and detailed review comments, which have contributed to the high standard of this collection. This collection includes three major parts: (1) Algorithms and Programming, (2) Machine Learning and Computer Vision; (3) Artificial Intelligence and Innovations, with most up-to-date findings and technologies being discussed. We believe participants of AICS2022 have gained knowledge as well as met new friends in the same field. And we hope this collection can benefit the readers in the same way.
