针对目前LCD缺陷检测速度较慢、检测精度较低的现状,本文提出一种YOLOv5s轻量化改进模型来检测识别LCD所存在的缺陷情况。通过改进上采样CARAFE算子进行Nearest的替换,并修改其kencoder与kreassembly两项参数进行对比;同时,增加CBAM注意力机制,更加关注目标区域特征信息以提升模型召回率;最后进行轻量化设计替换C3为C3_Ghost,以达到参数量、运输量以及模型大小的减小。实验结果说明,改进YOLOv5s算法在原模型基础上,准确率P提高了2.1%,召回率R提高了5.4%,模型平均精度mAP达到88.8%,相对于改进前提高了2.1%,参数量和运算量分别减少了15.6%和20.9%,并且模型大小减少了14.6%。整体而言,改进后的算法模型更加轻量化,模型MB减小并且参数量以及运算量相对减少,因此方便对低算力硬件进行部署,同时也为LCD工厂智能检测技术提供一定技术参考。

网络空间对抗形态正变得更加复杂,其中掺杂了人工智能、躲避逃逸、情报收集、社会工程、地缘政治等多种因素。目前威胁情报IOC特征主要被用来识别受控主机以及C&C终端连接行为;另外通过关联拓展IOC进行黑客组织溯源。以全流量存储、回溯和全球APT威胁情报监测为数据基础,提出基于IOC拓展指标和TTP规则、模型关联的APT攻击识别和背景溯源方案,可以将传统的基于时间点的检测模式延伸到基于历史时间窗的检测模式,能够更加充分地应对APT的持续性和长期性,同时也成为APT组织背景溯源的有效途径之一。

在ICD-9-CM-3中产科系统的手术操作因临床书写相同,手术操作过程相似,但编码往往不同,编码员在编码时常有误编。列举某院病案质控发现的产科手术操作编码错误较多的几种编码,例如催产素静滴、人工破膜引产术、会阴切开术、会阴裂伤修补术、剖宫产术、子宫球囊置入术等,探讨分析其编码要点及查找方法,总结产科中催产素静滴编码时需要注意是否药物增强分娩;人工破膜引产术根据操作时是否进入产程编码于73.01、73.09;会阴切开术根据是否伴有产钳或真空吸引操作编码于73.6、72.1、72.21、72.31、72.71;会阴裂伤修补术根据疾病性质编码于71.71、75.69、71.79;剖宫产术根据目的不同编码于74.1、74.91;子宫球囊置入术根据置入球囊目的不同编码于69.91、73.1、75.8;分娩后清宫术根据术式编码于69.02、69.52。编码员需提升临床基础知识和病案专业技能,熟练掌握产科手术操作编码规则,并与临床保持良好沟通,才能提高编码准确性。
