CSRankings: Computer Science Rankings

https://csrankings.org/#/fromyear/2011/toyear/2021/index?all&us

CSRanking好像是按照CS faculty pulication數量來排名的。UCSD也許是因為在AI, VIsion, MLP等領域publication比較多，而排在了#4. 

This ranking is designed to identify institutions and faculty actively engaged in research across a number of areas of computer science, based on the number of publications by faculty that have appeared at the most selective conferences in each area of computer science (see the FAQ for more details).
