A Random Walk of Network Science Research: Sub-modularity, Large Graphs Computation and File System Support
Faculty of Information Technology of Macau University of Science and Technology and Macau Institute of Smart City jointly held a seminar at Room 317, Block Non May 4th, 2017. Prof. John C.S. Lui was the invited speaker. Prof. Lui’s talk was on “A Random Walk of Network Science Research: Sub-modularity, Large Graphs Computation and File System Support”. Around 80 students and faculty members attended the seminar, including the Dean of the Faculty of Information Technology Prof. Zhang Du and the Assistant Dean Prof. Li Jianqing.
Abstract:
In the first part of the talk, Prof. Lui provided some motivation of some network science research problems, in particular, he talked about how one can combine theory of sub-modularity and probabilistic counting data structures to information discovery and computation on large graphs. He also discussed how one should re-design the file system support so as to provide a more efficient computation on network science problems. In the second part of his talk, he briefly went over his other research efforts, as well as his personal philosophy on teaching & administration.
