ContactHandover: Contact-Guided Robot-to-Human Object Handover

no code implementations1 Apr 2024 Zixi Wang, Zeyi Liu, Nicolas Ouporov, Shuran Song

We propose ContactHandover, a robot to human handover system that consists of two phases: a contact-guided grasping phase and an object delivery phase.

Motif-aware Riemannian Graph Neural Network with Generative-Contrastive Learning

1 code implementation2 Jan 2024 Li Sun, Zhenhao Huang, Zixi Wang, Feiyang Wang, Hao Peng, Philip Yu

In light of the issues above, we propose the problem of \emph{Motif-aware Riemannian Graph Representation Learning}, seeking a numerically stable encoder to capture motif regularity in a diverse-curvature manifold without labels.

QMGeo: Differentially Private Federated Learning via Stochastic Quantization with Mixed Truncated Geometric Distribution

no code implementations10 Dec 2023 Zixi Wang, M. Cenk Gursoy

Several differential privacy (DP) mechanisms have been proposed to provide provable privacy guarantees by introducing randomness into the framework, and majority of these mechanisms rely on injecting additive noise.

Monitoring and Adapting ML Models on Mobile Devices

no code implementations12 May 2023 Wei Hao, Zixi Wang, Lauren Hong, Lingxiao Li, Nader Karayanni, Chengzhi Mao, Junfeng Yang, Asaf Cidon

ML models are increasingly being pushed to mobile devices, for low-latency inference and offline operation.

High Noise Immune Time-domain Inversion via Cascade Network (TICaN) for Complex Scatterers

no code implementations3 Mar 2022 Hongyu Gao, Yinpeng Wang, Qiang Ren, Zixi Wang, Liangcheng Deng, Chenyu Shi

In this paper, a high noise immune time-domain inversion cascade network (TICaN) is proposed to reconstruct scatterers from the measured electromagnetic fields.

Distinguishing 4-dimensional geometries via profinite completions

no code implementations7 Nov 2020 Jiming Ma, Zixi Wang

For a closed orientable Seifert fibred 4-manifold $M$, we show that whether $M$ is geometric could be detected by the profinite completion of its fundamental group.
