Boosting Multitask Learning on Graphs through Higher-Order Task Affinities

3 code implementations24 Jun 2023 Dongyue Li, Haotian Ju, Aneesh Sharma, Hongyang R. Zhang

Lastly, we provide a theoretical analysis to show that under a planted block model of tasks on graphs, our affinity scores can provably separate tasks into groups.

Robust Fine-Tuning of Deep Neural Networks with Hessian-based Generalization Guarantees

3 code implementations6 Jun 2022 Haotian Ju, Dongyue Li, Hongyang R. Zhang

We study the generalization properties of fine-tuning to understand the problem of overfitting, which has often been observed (e. g., when the target dataset is small or when the training labels are noisy).
