About the lecture

Invited speakers will talk about cutting-edge topics in their respective fields, mainly based on the results of the invited speakers.
On the other hand, the organising committee members’ talks will be designed to be tutorials in their respective fields and will cover basic topics to the latest research, without assuming any prior knowledge.
