CISAT is centered around computer information science and technology, focusing on the application of this technology in big data, artificial intelligence and intelligent transportation. In terms of big data, computer information science and technology is mainly used for data collection, storage, processing and analysis. In artificial intelligence, computer information science and technology is mainly used in the fields of algorithm design, machine learning and deep learning. In intelligent transportation, computer information science and technology techniques are mainly used in the development of intelligent transportation systems and automatic driving technologies. Based on these wide-ranging application prospects, this conference is not only to provide a platform for the convergence of cutting-edge research results, but also to serve as a catalyst for further discussions on solutions such as information system security and AI ethics.
