CylinderTag: An Accurate and Flexible Marker for Cylinder-Shape Objects Pose Estimation Based on Projective Invariants

1 code implementation20 Oct 2023 Shaoan Wang, Mingzhu Zhu, Yaoqing Hu, Dongyue Li, Fusong Yuan, Junzhi Yu

Experimental results demonstrate that the CylinderTag is a highly promising visual marker for use on cylindrical-like surfaces, thus offering important guidance for future research on high-precision visual localization of cylinder-shaped objects.

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.

Noise Stability Optimization for Flat Minima with Tight Rates

no code implementations14 Jun 2023 Haotian Ju, Dongyue Li, Hongyang R. Zhang

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

Identification of Negative Transfers in Multitask Learning Using Surrogate Models

2 code implementations25 Mar 2023 Dongyue Li, Huy L. Nguyen, Hongyang R. Zhang

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.

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).

Improved Regularization and Robustness for Fine-tuning in Neural Networks

1 code implementation NeurIPS 2021 Dongyue Li, Hongyang R. Zhang

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.
