What i am most impressed about this paper is that it is primarily from CMU with 5 authors and 1 from Google (with the legend Quoc from Google and Ruslan Salakhutdinov is also excellent). Even though the CMU team may have had the original ideas, I guess the golden age of ML adage still holds despite their contributions related to dual-masking-plus-caching - "it's a golden age so long as you have access to massive amounts of compute and storage".
