Design of Cold Chain Traceability System Based on Internet of Things

Zhao-xi CHEN, Xi-ai CHEN, Dong-hong CHEN, Ya-qiong FU
2017 DEStech Transactions on Computer Science and Engineering  
A cold chain traceability system controlled via the Internet of Things technology was developed to investigate the details of the cold chain logistics process. This system includes the logistics environment detection part and the cloud data service part. By the cold chain traceability system, it is able to store the ambient temperature data, humidity data and geographic location data in the cold chain logistics process locally and transmit them through the GPRS to the cloud data service

Ensemble Network Architecture for Deep Reinforcement Learning

Xi-liang Chen, Lei Cao, Chen-xi Li, Zhi-xiong Xu, Jun Lai
2018 Mathematical Problems in Engineering  
The popular deep Q learning algorithm is known to be instability because of the Q-value's shake and overestimation action values under certain conditions. These issues tend to adversely affect their performance. In this paper, we develop the ensemble network architecture for deep reinforcement learning which is based on value function approximation. The temporal ensemble stabilizes the training process by reducing the variance of target approximation error and the ensemble of target values

Prenatal Diagnosis of Holt–Oram Syndrome With a Novel Mutation of TBX5 Gene: A Case Report

Guan-nan He, Xue-yan Wang, Min Kang, Xi-min Chen, Na Xi, Jing Zhao, Xi Chen
2021 Frontiers in Pediatrics  
Holt–Oram syndrome (HOS) is an autosomal dominant disorder caused by mutations of TBX5 gene.Case presentation: We report a fetus with HOS diagnosed sonographically at 23 weeks of gestation. The fetal parents are non-consanguineous. The fetus exhibited short radius and ulna, inability to supinate the hands, absence of the right thumb, and heart ventricular septal defect (VSD), while the fetal father exhibited VSD and short radius and ulna only. Fetal brother had cubitus valgus and thumb
more » ... , except for VSD, short radius and ulna. The pregnancy was terminated. Whole-exome sequencing (WES) revealed a novel mutation in the TBX5 (c.510+1G>A) in the fetus inherited from the father. The variant (c.510+1G>A) occurs at splice donor and may alter TBX5 gene function by impact on splicing. It was not previously reported in China.Conclusion: Our case reported a novel mutation in TBX5, which expanded the known genetic variants associated with HOS.

Pruning Ternary Quantization [article]

Dan Liu, Xi Chen, Jie Fu, Chen Ma, Xue Liu
2022 arXiv   pre-print
Inference time, model size, and accuracy are three key factors in deep model compression. Most of the existing work addresses these three key factors separately as it is difficult to optimize them all at the same time. For example, low-bit quantization aims at obtaining a faster model; weight sharing quantization aims at improving compression ratio and accuracy; and mixed-precision quantization aims at balancing accuracy and inference time. To simultaneously optimize bit-width, model size, and
more » ... ccuracy, we propose pruning ternary quantization (PTQ): a simple, effective, symmetric ternary quantization method. We integrate L2 normalization, pruning, and the weight decay term to reduce the weight discrepancy in the gradient estimator during quantization, thus producing highly compressed ternary weights. Our method brings the highest test accuracy and the highest compression ratio. For example, it produces a 939kb (49×) 2bit ternary ResNet-18 model with only 4% accuracy drop on the ImageNet dataset. It compresses 170MB Mask R-CNN to 5MB (34×) with only 2.8% average precision drop. Our method is verified on image classification, object detection/segmentation tasks with different network structures such as ResNet-18, ResNet-50, and MobileNetV2.

Almost Limited Sets in Banach Lattices [article]

Jin Xi Chen, Zi Li Chen, Guo Xing Ji
2013 arXiv   pre-print
We introduce and study the class of almost limited sets in Banach lattices, that is, sets on which every disjoint weak^* null sequence of functionals converges uniformly to zero. It is established that a Banach lattice has order continuous norm if and only if almost limited sets and L-weakly compact sets coincide. In particular, in terms of almost Dunford-Pettis operators into c_0, we give an operator characterization of those σ-Dedekind complete Banach lattices whose relatively weakly compact

Testing Unateness Nearly Optimally [article]

Xi Chen, Erik Waingarten
2019 arXiv   pre-print
We present an Õ(n^2/3/ϵ^2)-query algorithm that tests whether an unknown Boolean function f{0,1}^n→{0,1} is unate (i.e., every variable is either non-decreasing or non-increasing) or ϵ-far from unate. The upper bound is nearly optimal given the Ω̃(n^2/3) lower bound of [CWX17a]. The algorithm builds on a novel use of the binary search procedure and its analysis over long random paths.
