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.

It leads to a 17. 7% (and 12. 8%) reduction in the trace (and largest eigenvalue) of the Hessian matrix of the loss surface.

This problem is computationally challenging since the number of subsets grows exponentially with the number of source tasks; efficient heuristics for subset selection do not always capture the relationship between task subsets and multitask learning performances.

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).

We present a PAC-Bayes generalization bound that depends on the distance traveled in each layer during fine-tuning and the noise stability of the fine-tuned model.
