A Comprehensive Survey of 3D Dense Captioning: Localizing and Describing Objects in 3D Scenes

no code implementations12 Mar 2024 Ting Yu, Xiaojun Lin, Shuhui Wang, Weiguo Sheng, Qingming Huang, Jun Yu

Three-Dimensional (3D) dense captioning is an emerging vision-language bridging task that aims to generate multiple detailed and accurate descriptions for 3D scenes.

SPriFed-OMP: A Differentially Private Federated Learning Algorithm for Sparse Basis Recovery

no code implementations29 Feb 2024 Ajinkya Kiran Mulay, Xiaojun Lin

However, there has been little work that studies sparse basis recovery in the Federated Learning (FL) setting, where the client data's differential privacy (DP) must also be simultaneously protected.

Code-Based English Models Surprising Performance on Chinese QA Pair Extraction Task

no code implementations16 Jan 2024 Linghan Zheng, Hui Liu, Xiaojun Lin, Jiayuan Dong, Yue Sheng, Gang Shi, Zhiwei Liu, Hongwei Chen

In previous studies, code-based models have consistently outperformed text-based models in reasoning-intensive scenarios.

Insurance Contract for High Renewable Energy Integration

no code implementations21 Sep 2022 Dongwei Zhao, Hao Wang, Jianwei Huang, Xiaojun Lin

A proper insurance design needs to resolve the following two challenges: (i) users' reliability preference is private information; and (ii) the insurance design is tightly coupled with the renewable energy investment decision.

On the Generalization Power of the Overfitted Three-Layer Neural Tangent Kernel Model

no code implementations4 Jun 2022 Peizhong Ju, Xiaojun Lin, Ness B. Shroff

Our upper bound reveals that, between the two hidden-layers, the test error descends faster with respect to the number of neurons in the second hidden-layer (the one closer to the output) than with respect to that in the first hidden-layer (the one closer to the input).

SeedGNN: Graph Neural Networks for Supervised Seeded Graph Matching

1 code implementation26 May 2022 Liren Yu, Jiaming Xu, Xiaojun Lin

However, most previous GNNs for this task use a semi-supervised approach, which requires a large number of seeds and cannot learn knowledge that is transferable to unseen graphs.

Time-of-use Pricing for Energy Storage Investment

no code implementations13 Dec 2021 Dongwei Zhao, Hao Wang, Jianwei Huang, Xiaojun Lin

Such a pricing scheme provides users with incentives to invest in behind-the-meter energy storage and to shift peak load towards low-price intervals.

Student-Teacher Learning from Clean Inputs to Noisy Inputs

no code implementations CVPR 2021 Guanzhe Hong, Zhiyuan Mao, Xiaojun Lin, Stanley H. Chan

Feature-based student-teacher learning, a training method that encourages the student's hidden features to mimic those of the teacher network, is empirically successful in transferring the knowledge from a pre-trained teacher network to the student network.

On the Generalization Power of Overfitted Two-Layer Neural Tangent Kernel Models

no code implementations9 Mar 2021 Peizhong Ju, Xiaojun Lin, Ness B. Shroff

Specifically, for a class of learnable functions, we provide a new upper bound of the generalization error that approaches a small limiting value, even when the number of neurons $p$ approaches infinity.

The Power of $D$-hops in Matching Power-Law Graphs

no code implementations23 Feb 2021 Liren Yu, Jiaming Xu, Xiaojun Lin

Under the Chung-Lu random graph model with $n$ vertices, max degree $\Theta(\sqrt{n})$, and the power-law exponent $2<\beta<3$, we show that as soon as $D> \frac{4-\beta}{3-\beta}$, by optimally choosing the first slice, with high probability our algorithm can correctly match a constant fraction of the true pairs without any error, provided with only $\Omega((\log n)^{4-\beta})$ initial seeds.

Contract-based Time-of-use Pricing for Energy Storage Investment

no code implementations26 Sep 2020 Dongwei Zhao, Hao Wang, Jianwei Huang, Xiaojun Lin

We also show that the proposed contracts can reduce the system social cost by over 30%, compared with no storage investment benchmark.

Graph Matching with Partially-Correct Seeds

1 code implementation8 Apr 2020 Liren Yu, Jiaming Xu, Xiaojun Lin

We establish non-asymptotic performance guarantees of perfect matching for both $1$-hop and $2$-hop algorithms, showing that our new $2$-hop algorithm requires substantially fewer correct seeds than the $1$-hop algorithm when graphs are sparse.

Virtual Energy Storage Sharing and Capacity Allocation

no code implementations3 Jul 2019 Dongwei Zhao, Hao Wang, Jianwei Huang, Xiaojun Lin

In our simulation results, the proposed storage virtualization model can reduce the physical energy storage investment of the aggregator by 54. 3% and reduce the users' total costs by 34. 7%, compared to the case where users acquire their own physical storage.
