For example both 2 and 4 are factors of 8 because 2 x 4 = 8. How do you find the GCF? In order to find the Greatest Common Factor or GCF, first all the factors must be known between two numbers. For example: The factors of 12: 1, 2, 3, 4, 6, and 12. The factors of...

MixGCF: An Improved Training Method for Graph Neural Network-based Recommender Systemskeg.cs.tsinghua.edu.cn/ 1. 背景 GNN在协同过滤相关方法中达到了最优的效果,从隐式反馈中负采样是协同过滤中需要面临的一大难题。当前在基于图的协同过滤方法中,负采样方法探索的还比较少。本文提出了即插即用的MixGCF负采样...
Both the main task and the auxiliary task face the noise problem and the distilling hard negative problem. However, existing GNN-CF models only focus on one of them and ignore the other. Aiming to solve the two problems in a unified framework, we propose a Multi-Mixing strategy for GNN-...
Leucine Rich Repeat of Flightless-1 Interacting Protein 1/GC-binding factor 2 (LRRFIP1/GCF2) cDNA was cloned for a transcriptional repressor GCF2, which bound sequence-specifically to a GC-rich element of epidermal growth factor receptor (EGFR) gene and repressed its promotor. LRRFIP1/GCF2 ...
