TCGAbiolinks包报错:“Can't subset columns past the end”

2022年4月,TCGA数据库进行了一次更新,原来的HT-RNASeq数据被替换成了Star-RNASeq,这导致原有的TCGAbiolinks包能正常下载数据,但是不能用GDCprepare函数正常合并下载的数据集。如果用之前版本的包,在尝试这一步的时候会报错。ERROR:Can'tsubsetcolumnspasttheend解决的办法就是升级TCGABiolinks这个包,不过由于Biocmanager上的版本比较低,建议直接从Github进行更新。BiocManager::install("BioinformaticsFMRP/TCGAbiolinksGUI.data")BiocMan

WWW'22 Graph Neural Transport Networks with Non-local Attentions for Recommender Systems

GraphNeuralTransportNetworkswithNon-localAttentionsforRecommenderSystems用于推荐系统的非局部注意的图神经传输网络来源:WWW2022摘要:通常,GNN通过在本地邻居之间传播和聚合消息来生成用户/项的嵌入。因此,GNN捕获远程依赖关系的能力在很大程度上取决于它们的深度。然而,简单地训练深度gnn会产生瓶颈效应,例如过拟合和过平滑等,无法得到较好的训练效果。为了解决这个问题,作者提出了图最优传输网络(GOTNet)来捕获在不增加GNN深度的情况下的长期依赖关系。GOTNet能够只使用浅层GNN来同时捕获图中的本地和非本地消息,
