It was a great pleasure to welcome all the participants from different countries to the 2020 International Conference on Machine Learning and Computer Application (ICMLCA2020) in Shangri-La, China during September 11-13, 2020. This three-day conference was presented by AEIC Academic Exchange Information Center. This unique international conference provided a forum for about 70 academics, researchers and practitioners from many industries to exchange ideas and shared recent developments in the fields of Machine Learning, Computer Application and Robotic. We provided an opportunity to collaborate and advance the theory and practice of major trends in related fields and as a bridge for scholars to share and inspire their opinion.The conference model was divided into two sessions, including oral presentations and keynote speeches. In the first part, some scholars, whose submissions were selected as the excellent papers, were given 15 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-45 minutes to hold their speeches. In this conference, we were greatly honor to have invited three distinguished experts to serve as our Conference Chairmen. They were Prof. Zhenghua Xu, from State Key Laboratory of Reliability and Intelligence of Electrical Equipment, Hebei University of Technology, Prof.Wei Wei, from Xi’an University of Technology, senior member of IEEE, and Assoc. professor Dr.Wael Yafooz, from Dean, Faculty computer and information technology, al-madinah international university, Malaysia.During the conference, we invited five industry elites to present their insightful speeches. The first keynote speaker, Prof. Xuebin Chen, from North China University of Science and Technology. His research direct on Network Security, Big Data, Data Security. Prof. Zhenghua Xu, from State Key Laboratory of Reliability and Intelligence of Electrical Equipment, Hebei University of Technology. His research focuses on topics within artificial intelligence and data mining, especially deep learning, medical artificial intelligence, health data mining, and reinforcement learning. The third keynote speaker, Prof. Ahmad T. Al-Taani, from Department of Computer Sciences, Faculty of Information Technology, Yarmouk University, IRBID, JORDAN, shared a speech on his specialty related to Part-of-Speech Tagging using Swarm Intelligence. Mr. Nirmalya Thakur presented an insightful speech on Machine Learning and its Applications for Developing Emotional Intelligence in Smart Homes. His talk aims to introduce and discuss the immense potential at the intersection of Machine Learning with Internet of Things, Human-Computer Interaction and their related disciplines. As the last keynote speaker, A.P. HAN-Teng Liao, talked about Artificial Intelligence Standardization: Implications for Machine Learning Innovation and Application. This talk summarized the challenges and opportunities, surrounding machine learning, for intelligent innovations and applications.We are glad to share with you that we received lots of submissions from the conference and we selected a bunch of high-quality papers and compiled them into the proceedings after rigorously reviewed them. These papers feature following topics but are not limited to: Machine Learning, Computer Applications, Robotic and other related topics. All the papers have been through rigorous review and process to meet the requirements of International publication standard.List of Committee member, Conference Chairman, Academic Committee Chairman, Organizing Committees, Academic Committees Member, International Technical Program Committees Member, Organization Committees Memberare availble in this pdf.
