摘要：margin在机器学习中具有很重要的意义,基于margin的特征选择方法就是从分类的角度对特征集各特征的权重进行分析。该文对不同的margin进行了分析,提出将sample-margin和hypothesis-margin分别作为特征选择标准对SBS特征选择方法进行改进,然后设计具有最佳超参数的SVM多项式分类器进行人脸识别。实验在FRERT人脸图像库上进行并与Relief特征选择方法进行了比较,对SVM和NN分类器的实验结果也进行了分析。实验结果显示:该文提出的人脸识别特征选择及识别方法是有效、适用的。

摘要：Optimal resource allocation with an objective of maximizing the system capacity is an NP-hard problem in multihop cellular networks. Hence, different heuristic algorithms have been developed over the years that would improve the network system capacity. In this paper, a novel cluster-based architecture is proposed for a two-hop cellular network whereby the transmission distance between any communicating pair is restricted to half the cell radius. In this design, a given radio resource is used by two simultaneously communicating pairs in every hexagonal cell, but for only half the time slot period. The characteristic feature of this cluster-based design is that it enables a frequency reuse ratio of one. The proposed hierarchical system is analyzed and tested under realistic propagation conditions including lognormal shadowing. It has been observed that the system capacity of a cluster-based design is 2.5 times that obtained from the single-hop cellular system with no relaying. In addition, the cluster-based design achieves higher capacity compared to state-of-the-art two-hop algorithms. This is an important finding since the hierarchical cluster-based approach has fewer degrees of freedom in the selection of the routing path for the end-to-end connection. Practical routing algorithms should be able to benefit from this.

摘要：研究了京东方小尺寸出现的一系列高低温测试过程中出现的重力Mura和Bubble问题,主要为Photo Spacer(PS)存在较大波动,导致LC margin评价出现偏差,或者LC margin评价后,实际量产PS存在批次性差异。通过对问题根源的分析,一方面寻找精确测试LC margin的方案;另一方面对于真实margin过小的产品,研究LC量与实际PS高度进行匹配,以联动的方式管控液晶量的滴入,从而克服PS波动过大引起的LC偏出真实margin的问题。鉴于目前几乎所有ADS Mobile产品面临的面贴按压水波纹和发黄的现状,产品在设计时需要增加Main PS的密度,直接影响PS的压缩率,导致LC margin过小。而当PS工艺管控能力无法满足LC margin过小所需的精度时,从LC与PS联动的角度研究了解决问题的方案,从而保证产品品质的同时,减小工程管控风险。
