Enabling tabular deep learning when $d \gg n$ with an auxiliary knowledge graph

no code implementations7 Jun 2023 Camilo Ruiz, Hongyu Ren, Kexin Huang, Jure Leskovec

However, for tabular datasets with extremely high $d$-dimensional features but limited $n$ samples (i. e. $d \gg n$), machine learning models struggle to achieve strong performance due to the risk of overfitting.

TuneUp: A Simple Improved Training Strategy for Graph Neural Networks

no code implementations26 Oct 2022 Weihua Hu, Kaidi Cao, Kexin Huang, Edward W Huang, Karthik Subbian, Kenji Kawaguchi, Jure Leskovec

Extensive evaluation of TuneUp on five diverse GNN architectures, three types of prediction tasks, and both transductive and inductive settings shows that TuneUp significantly improves the performance of the base GNN on tail nodes, while often even improving the performance on head nodes.

Graph Meta Learning via Local Subgraphs

1 code implementation NeurIPS 2020 Kexin Huang, Marinka Zitnik

G-Meta learns how to quickly adapt to a new task using only a handful of nodes or edges in the new task and does so by learning from data points in other graphs or related, albeit disjoint label sets.
