496,835 条来自 AG 新闻语料库 4 大类别超过 2000 个新闻源的新闻文章,数据集仅仅援用了标题和描述字段。每个类别分别拥有 30,000 个训练样本及 1900 个测试样本。 README: AG's News Topic Classification Dataset Version 3, Updated 09/09/2015 ORIGIN AG is a collection of more than 1 million news articles. News articles have been gathered from more than 2000 news sources by ComeToMyHead in more than 1 year of activity. ComeToMyHead is an academic news search engine which has been running since July, 2004. The dataset is provided by the academic comunity for research purposes in data mining (clustering, classification, etc), information retrieval (ranking, search, etc), xml, data compression, data streaming, and any other non-commercial activity. For more information, please refer to the link http://www.di.unipi.it/~gulli/AG_corpus_of_news_articles.html . The AG's news topic classification dataset is constructed by Xiang Zhang (xiang.zhang@nyu.edu) from the dataset above. It is used as a text classification benchmark in the following paper: Xiang Zhang, Junbo Zhao, Yann LeCun. Character-level Convolutional Networks for Text Classification. Advances in Neural Information Processing Systems 28 (NIPS 2015). DESCRIPTION The AG's news topic classification dataset is constructed by choosing 4 largest classes from the original corpus. Each class contains 30,000 training samples and 1,900 testing samples. The total number of training samples is 120,000 and testing 7,600. The file classes.txt contains a list of classes corresponding to each label. The files train.csv and test.csv contain all the training samples as comma-sparated values. There are 3 columns in them, corresponding to class index (1 to 4), title and description. The title and description are escaped using double quotes ("), and any internal double quote is escaped by 2 double quotes (""). New lines are escaped by a backslash followed with an "n" character, that is "\n".

自己搭建并测试可以跑的AG-Admin项目,包括前端与后端项目。 https://git.oschina.net/geek_qi/AG-Config.git: Authentication is required but no CredentialsProvider has been registered 这个错误可以不用理,主要是配置文件在git上无访问权限。不会影响使用,403错误,可以调高gate的限流。

针对“先规划后平滑”的避障规划方法会改变原始路径的问题,将避障规划问题转化为最优控制问题来求解,在不改变原始路径的情况下实现了运动轨迹的优化与平滑。首先,实现了仓储物流 AGV 的运动约束、避碰约束、路径通道约束以及两点边界条件的量化,建立了优化问题的约束条件,并以最短避障时间为目标建立了目标函数。其次,基于直接配点法将最优控制问题离散成带约束的非线性规划问题,运用内点法对非线性规划问题进行寻优。最后,通过算例对运动轨迹的优化与平滑结果进行了考证。考证结果显示:在移动和静态障碍物的环境下,基于直接配点法的避障规划均可以成功规划出一条满足AGV 运动约束的避障轨迹。 通过搭建实验环境对本文的识障和避障策略与方法进行了验证。在障碍物最近凸 点的位置识别精度方面,以横、纵坐标平均误差建立评价指标;在障碍物轮廓识别精度方 面,以尺寸或位置的识别值与相应的实际值之差的绝对值建立轮廓识别的精度评价指标; 在避障运动轨迹规划与平滑方面,基于直接配点法可以在单个和多个静态障碍物环境下成 功规划出一条避障轨迹且避障轨迹较为平滑,满足 AGV 的运动约束。
贴片保险丝是一般电子产品中常被使用来做为电路上过电流或短路保护的元器件。保险丝会根据其熔断时间及耐脉冲能力(与I2t特性相关)来区分不同的熔断特性。因此各家保险丝制造商会选择不同的金属材料特性当做熔丝,结合适当的基体材料及设计结构来制造出适合的熔断特性保险丝。   以目前市场上的低电压规格(≤63Vdc)的贴片保险丝,依据其熔丝的结构,基本上可以区分为单层金属及双层金属共熔结构。AEM科技所独创的SolidMatrix:registered:积层独石封装技术所生产的保险丝,其熔丝设计就是采用单层Ag合金结构(照片1、2)。然而市场上大多数贩售的保险丝,采用的是Al2O3陶瓷或PCB基板覆盖聚合物保护层技术,其熔丝

AgNO3溶液中超声辐照石英基板,然后在200至800摄氏度之间的高温(T-a)在氮气气氛中进行后退火。超声波和热处理。 观察到由Ag团簇上的局部表面等离子体激元(LSP)诱导的吸收光谱。 最突出的吸收发生在Ta = 400摄氏度。从Ta = 200到400摄氏度,SiO2上的AgNO3经历热分解,Ag团簇形成和成熟。 从Ta = 600至800℃,形成Ag氧化物纳米环。 将LSPs应用于掺杂Si纳米晶体的SiO2(Si-NC:SiO2)薄膜可增强Si-NCs的光致发光(PL),在Ta = 400摄氏度下可获得最大3.6倍的增强。PL增强归因于LSP场耦合到Si-NC的激子偶极矩。
