Patent number: 11804074Abstract: The present disclosure relates to a method for recognizing facial expressions based on adversarial elimination. First, a facial expression recognition network is built based on a deep convolutional neural network. On a natural facial expression data set, the facial expression recognition network is trained through a loss function to make facial expression features easier to distinguish. Then some key features of input images are actively eliminated by using an improved confrontation elimination method to generate a new data set to train new networks with different weight distributions and feature extraction capabilities, forcing the network to perform expression classification discrimination based on more features, which reduces the influence of interference factors such as occlusion on the network recognition accuracy rate, and improving the robustness of the facial expression recognition network.Type: GrantFiled: September 27, 2021Date of Patent: October 31, 2023Assignees: Chongqing University, University of Electronic Science and Technology of China, Dibi (Chongqing) Intelligent Technology Research Institute Co., Ltd., Star Institute of Intelligent SystemsInventors: Yongduan Song, Feng Yang, Rui Li, Yiwen Zhang, Haoyuan Zhong, Jian Zhang, Shengtao Pan, Siyu Li, Zhengtao Yu

Publication number: 20230128254Abstract: A method for multi-spectral scattering-matrix tomography includes a step of splitting an input light signal into an incident light signal and a reference light signal. The sample light signal is directed to a sample in either a reflection configuration or a transmission configuration such that an output light signal includes light scattered from or transmitted through the sample. The incident signal and the reference light signal are directed to a camera angled to allow for amplitude and phase to be calculated by off-axis holography. A total light signal is measured with a camera that is a coherent sum of the reference light signal and the output signal. The total light signal for each light frequency and each incident angle are collected as collected total light signal data. A computing device derives an image of the sample from a calculated reflection matrix or transmission matrix or both of them.Type: ApplicationFiled: October 24, 2022Publication date: April 27, 2023Inventors: Chia Wei HSU, Zeyu WANG, Yiwen ZHANG

According to the method of the present disclosure, coarse-grained pruning is performed on a neural network model by using a differential evolution algorithm first, and the coarse-grained space is quickly searched through an entropy importance criterion and an objective function with good guidance to obtain a near-optimal neural network structure. Then fine-grained search space is built on the basis of an optimal individual obtained from the coarse-grained search, and fine-grained pruning is performed on the neural network model by a differential evolution algorithm to obtain a network model with an optimal structure. Finally, the performance of the optimal model is restored by using a multi-teacher multi-step knowledge distillation network to reach the precision of an original model.Type: ApplicationFiled: September 27, 2021Publication date: November 3, 2022Applicants: Chongqing University, University of Electronic Science and Technology of China, Dibi (Chongqing) Intelligent Technology Research Institute Co., Ltd., Star Institute of Intelligent SystemsInventors: Yongduan Song, Feng Yang, Rui Li, Shengtao Pan, Siyu Li, Yiwen Zhang, Jian Zhang, Zhengtao Yu, Shichun Wang

Publication number: 20220239598Abstract: A distributed sender driven Admission Control System (ACS) is described herein, leveraging Weighted-Fair Quality of Service (QoS) queues, found in standard NICs and switches, to guarantee RPC level latency service level objectives (SLOs) by a judicious selection of QoS weights and traffic-mix across QoS queues. ACS installs cluster-wide RPC latency SLOs by mapping LS RPCs to higher weight QoS queues, and coping with overloads by adaptively apportioning LS RPCs amongst QoS queues based on measured completion times for each queue. When the network demand spikes unexpectedly to predetermined threshold percentage of provisioned capacity, ACS achieves a latency SLO that is significantly lower than the state-of-art congestion control at the 99.9th-p and admits significantly more RPCs meeting SLO target when RPC sizes are not aligned with priorities.Type: ApplicationFiled: January 20, 2022Publication date: July 28, 2022Inventors: Gautam Kumar, Yiwen Zhang, Nandita Dukkipati, Xian Wu, Amin Vahdat
