DREAM-PCD: Deep Reconstruction and Enhancement of mmWave Radar Pointcloud

no code implementations27 Sep 2023 Ruixu Geng, Yadong Li, Dongheng Zhang, Jincheng Wu, Yating Gao, Yang Hu, Yan Chen

However, existing methods failed to simultaneously address the three main challenges in mmWave radar pointcloud reconstruction: specular information lost, low angular resolution, and strong interference and noise.

Strong Instance Segmentation Pipeline for MMSports Challenge

2 code implementations28 Sep 2022 Bo Yan, Fengliang Qi, Zhuang Li, Yadong Li, Hongbin Wang

The goal of ACM MMSports2022 DeepSportRadar Instance Segmentation Challenge is to tackle the segmentation of individual humans including players, coaches and referees on a basketball court.

Unsupervised Domain Adaptation for Device-free Gesture Recognition

no code implementations20 Nov 2021 Bin-Bin Zhang, Dongheng Zhang, Yadong Li, Yang Hu, Yan Chen

To tackle this challenge, we propose an unsupervised domain adaptation framework for device free gesture recognition by making effective use of the unlabeled target domain data.

Towards Domain-Independent and Real-Time Gesture Recognition Using mmWave Signal

1 code implementation11 Nov 2021 Yadong Li, Dongheng Zhang, Jinbo Chen, Jinwei Wan, Dong Zhang, Yang Hu, Qibin Sun, Yan Chen

To enhance the robustness of the system and reduce data collecting efforts, we design a data augmentation framework for mmWave signals based on correlations between signal patterns and gesture variations.

Reduced Form Capital Optimization

no code implementations15 May 2019 Yadong Li, Dimitri Offengenden, Jan Burgy

We formulate banks' capital optimization problem as a classic mean variance optimization, by leveraging an accurate linear approximation to the Shapely or Constrained Aumann-Shapley (CAS) allocation of max or nested max cost functions.
