Beyond Dense Connectivity: Explicit Sparsity for Scalable Recommendation
Yantao Yu · Sen Qiao · Lei Shen · Bing Wang · Xiaoyi Zeng
摘要
Recent progress in scaling large models has motivated recommender systems to increase model depth and capacity to better leverage massive behavioral data. However, recommendation inputs are high-dimensional and extremely sparse, and simply scaling dense backbones (e.g., deep MLPs) often yields di...
