JSRNN: Joint Sampling and Reconstruction Neural Networks for High Quality Image Compressed Sensing

no code implementations11 Nov 2022 Chunyan Zeng, Jiaxiang Ye, Zhifeng Wang, Nan Zhao, Minghu Wu

Most Deep Learning (DL) based Compressed Sensing (DCS) algorithms adopt a single neural network for signal reconstruction, and fail to jointly consider the influences of the sampling operation for reconstruction.

Spatio-Temporal Representation Learning Enhanced Source Cell-phone Recognition from Speech Recordings

no code implementations25 Aug 2022 Chunyan Zeng, Shixiong Feng, Zhifeng Wang, Xiangkui Wan, Yunfan Chen, Nan Zhao

In this paper, we propose a source cell-phone recognition method based on spatio-temporal representation learning, which includes two main parts: extraction of sequential Gaussian mean matrix features and construction of a recognition model based on spatio-temporal representation learning.

Abs-CAM: A Gradient Optimization Interpretable Approach for Explanation of Convolutional Neural Networks

no code implementations8 Jul 2022 Chunyan Zeng, Kang Yan, Zhifeng Wang, Yan Yu, Shiyan Xia, Nan Zhao

However, when this method uses backpropagation to obtain gradients, it will cause noise in the saliency map, and even locate features that are irrelevant to decisions.

The JDDC 2.0 Corpus: A Large-Scale Multimodal Multi-Turn Chinese Dialogue Dataset for E-commerce Customer Service

no code implementations27 Sep 2021 Nan Zhao, Haoran Li, Youzheng Wu, Xiaodong He, BoWen Zhou

We present the solutions of top-5 teams participating in the JDDC multimodal dialogue challenge based on this dataset, which provides valuable insights for further researches on the multimodal dialogue task.

Anomalous Motion of Particle Levitated by Laguerre-Gaussian beam

no code implementations14 Apr 2020 Yang Li, Lei-Ming Zhou, Nan Zhao

We calculated the scattering force distribution of a micro-particle trapped in an optical tweezers formed by the strongly focused LG beam, and showed that there exist stable trajectories of the particle that controlled by the negative torque.

Robust Federated Learning with Noisy Communication

no code implementations1 Nov 2019 Fan Ang, Li Chen, Nan Zhao, Yunfei Chen, Weidong Wang, F. Richard Yu

Nevertheless, it is impractical to achieve a perfect acquisition of the local models in wireless communication due to noise, which also brings serious effects on federated learning.

Recognition of Emotions using Kinects

no code implementations4 Aug 2015 Shun Li, Changye Zhu, Liqing Cui, Nan Zhao, Baobin Li, Tingshao Zhu

By using the NaiveBayes, RandomForests, libSVM and SMO classification, the recognition rate of natural and unnatural emotions can reach above 70%. It is concluded that using the Kinect system can be a new method in recognition of emotions.
