Fixed-size Objects Encoding for Visual Relationship Detection

no code implementations29 May 2020 Hengyue Pan, Xin Niu, Rongchun Li, Siqi Shen, Yong Dou

Instead, we propose a novel method to encode all background objects in each image by using one fixed-size vector (i. e., FBE vector).

Expressive Interviewing: A Conversational System for Coping with COVID-19

no code implementations EMNLP (NLP-COVID19) 2020 Charles Welch, Allison Lahnala, Verónica Pérez-Rosas, Siqi Shen, Sarah Seraj, Larry An, Kenneth Resnicow, James Pennebaker, Rada Mihalcea

The ongoing COVID-19 pandemic has raised concerns for many regarding personal and public health implications, financial security and economic stability.

HSC4D: Human-centered 4D Scene Capture in Large-scale Indoor-outdoor Space Using Wearable IMUs and LiDAR

1 code implementation CVPR 2022 Yudi Dai, Yitai Lin, Chenglu Wen, Siqi Shen, Lan Xu, Jingyi Yu, Yuexin Ma, Cheng Wang

We propose Human-centered 4D Scene Capture (HSC4D) to accurately and efficiently create a dynamic digital world, containing large-scale indoor-outdoor scenes, diverse human motions, and rich interactions between humans and environments.

FedGS: Federated Graph-based Sampling with Arbitrary Client Availability

1 code implementation25 Nov 2022 Zheng Wang, Xiaoliang Fan, Jianzhong Qi, Haibing Jin, Peizhen Yang, Siqi Shen, Cheng Wang

Second, constrained by the far-distance in data distribution of the sampled clients, we further minimize the variance of the numbers of times that the clients are sampled, to mitigate long-term bias.

SGLoc: Scene Geometry Encoding for Outdoor LiDAR Localization

no code implementations CVPR 2023 Wen Li, Shangshu Yu, Cheng Wang, Guosheng Hu, Siqi Shen, Chenglu Wen

In this work, we propose a novel LiDAR localization framework, SGLoc, which decouples the pose estimation to point cloud correspondence regression and pose estimation via this correspondence.

RELI11D: A Comprehensive Multimodal Human Motion Dataset and Method

no code implementations28 Mar 2024 Ming Yan, Yan Zhang, Shuqiang Cai, Shuqi Fan, Xincheng Lin, Yudi Dai, Siqi Shen, Chenglu Wen, Lan Xu, Yuexin Ma, Cheng Wang

Comprehensive capturing of human motions requires both accurate captures of complex poses and precise localization of the human within scenes.

Knowledge Enhanced Reflection Generation for Counseling Dialogues

no code implementations ACL 2022 Siqi Shen, Veronica Perez-Rosas, Charles Welch, Soujanya Poria, Rada Mihalcea

We propose a pipeline that collects domain knowledge through web mining, and show that retrieval from both domain-specific and commonsense knowledge bases improves the quality of generated responses.
