MARM: Unlocking the Future of Recommendation Systems through Memory Augmentation and Scalable Complexity

Xiao Lv, Jiangxia Cao, Shijie Guan +7

Scaling-law has guided the language model designing for past years, however, it is worth noting that the scaling laws of NLP cannot be directly applied to RecSys due to the followi…
