The Artificial Intelligence (AI) Lab was established in 1994 in the Department of Computer Science at Meiji University by Prof. Yoichi Hayashi, a well-known researcher in the field of AI who has highlighted the importance of the “black box” problem in trained neural networks.
He received an INAMORI research foundation (provides the Kyoto Prize) grant by proposing a unique integration scheme for fuzzy logic and neural networks. Furthermore, he has published over 200 peer-reviewed research publications on AI.
He is a worldwide pioneer in “rule extraction” from Big Data. His papers published in first class journals such as IEEE (Institute of Electrical and Electronics Engineers) Transactions on Neural Networks in 2000, has been cited more than 7500 times according to Google Scholar. From the 1990s, he has been devoted to research on innovative artificial intelligence (AI), rule extraction algorithms, Big Data analytics, the design of high-performance classifiers, and medical diagnoses such as the early detection of lifestyle-related diseases that have the potential to become chronic.
His research group is among the highest ranked at the worldwide level regarding high-performance classifiers and at the top in terms of rule extraction algorithms and/or systems.
Currently, his research group is concentrating on the development of innovative AI paradigms such as transparency and explainability for deep learning and their applications to fully automated mobile vehicles, Big Data analytics for time series financial, economic and marketing data, the early detection of lifestyle-related diseases such as diabetes mellitus, thyroid and liver disorders, hepatitis, and financial engineering such as credit scoring and assessment.
Our top priority is to challenge minds to devise innovative ideas that lead to the creation of technologies that will be applicable 20 years in the future!
Prof. Yoichi Hayashi received his Dr. Eng. degree in systems engineering from Tokyo University of Science, Tokyo in 1984. In 1986, he joined the Computer Science Department of Ibaraki University, Japan, as an Assistant Professor, and served as a Visiting Professor at University of Alabama, Birmingham (USA) and the University of Canterbury (New Zealand). Since 1996, he has been a Full Professor at the Computer Science Department, Meiji University, Tokyo. He also served as a full professor and the chairman of the department from 2004–2006. He has authored over 200 published peer-reviewed papers in computer science and has been a senior member of the IEEE since 2000.
His current research interests include AI, deep learning, machine learning, rule extraction, Big Data analytics, high-performance classifiers, and medical informatics. Since 1990, he has been promoting international research projects on AI and Big Data analytics with many researchers in the USA, Germany, Singapore, India, Switzerland, Poland, Austria, Taiwan, and the Philippines.
He is an editorial board member of Big Data and Cognitive Computing and Machine Learning and Knowledge Extraction, a review board member for Applied Intelligence, and an advisory board member for Current Pharmaceutical Biotechnology. He has also served as an associate editor for Artificial Intelligence in Medicine and IEEE Transactions on Fuzzy Systems and an action editor for Neural Networks.
He also has been a reviewer for 50 high ranking journals such as IEEE Transactions on Neural Networks, IEEE Transactions on Fuzzy Systems, IEEE Transactions on Data and Knowledge Engineering, IEEE Transactions on Systems, Man and Cybernetics, Knowledge-Based Systems, Neurocomputing, Neural Networks, Artificial Intelligence in Medicine, Information Sciences, Soft Computing, and Applied Intelligence, among others.
He has supervised Master’s and Ph.D. theses in computer science for foreign graduate students from the USA, China, Malaysia, India, Korea and Canada, displaying respect, sensitivity, and positivity to cultural and religious diversity and differences of opinion.
