k-means聚类代码
应用背景
聚类分析在客户分类、基因识别、文本分类、空间数据处理、卫星照片分析、医疗图像自动检测等领域有着广泛的应用,而其本身的研究也是一个蓬勃发展的领域,数据挖掘、统计学、机器学习、空间数据库技术、生物学和市场学的发展推动着聚类分析研究的进展,使它已成为数据挖掘研究中的一个热点,在市场分析中,通过聚类分析能帮助决策者识别不同特征的客户群以及各客户群的行为特征在生物工程研究中。
关键技术k均值算法是聚类分析中一种被广泛应用的启发式划分方法,具有简单、快速的优点。聚类是一个将数据集划分为若干个子集的过程,并使得同一集合内的数据对象具有较高的相似度,而不同集合中的数据对象则是不相似的,相似或不相似的度量是基于数
据对象描述属性的取值来确定的,通常就是利用各个聚类间的距离来进行描述的。聚类分析的基本指导思想是最大程度地实现类中对象相似度最大,类间对象相似度最小。

Apress-Pro-Android-Apps-Performance-Optimization-
I thank the team at Apress who made this book possible: Steve Anglin, Corbin Collins, Jim
Markham, and Jill Steinberg. Working with all of them was a real pleasure and I can with
confidence recommend them to any author.
I also want to thank the tech reviewers: Charles Cruz, Shane Kirk, and Eric Neff. They
provided invaluable feedback, often catching mistakes I would not have seen even after dozens of
readings.
To all my friends whom I did not get to see as often as I would have liked while I was working
on this book, I give my thanks too: Marcely, Mathieu, Marilen, Maurice, Katie, Maggie, Jean-René,
Ruby, Greg, Aline, Amy, and Gilles, I promise I will make up for the lost time. Last but not least, I
owe a lot to three people: Eddy Derick, Fabrice Bernard, and Jean-Louis Gassée. Sometimes all it
takes is an injured toe and a broken suitcase.

snmp4j初学代码
简单的连接snmp agent 然后get数据
在main函数中
Address targetAddress=GenericAddress.parse("udp:192.168.5.151/161");
TransportMapping transport=new DefaultUdpTransportMapping();
Snmp snmp=new Snmp(transport);
transport.listen();
CommunityTarget target=new CommunityTarget();
target.setCommunity(new OctetString("WinSpread"));
target.setAddress(targetAddress);
target.setRetries(3);
target.setTimeout(5000);
target.setVersion(1);
PDU request=new PDU();
request.setType(PDU.SET);
// request.add(new VariableBinding(new OID("IP-FORWARD-MIB::inetCidrRouteMetric4.ipv4")));
// request.add(new VariableBinding(new OID("IP-MIB::ipAdEntAddr")));
// request.add(new VariableBinding(new OID(".1.3.6.1.2.1.1.3.0")));

gathsrkernel
说明: LDPC校验矩阵生成,高斯消去法编码,BP译码程序,可以作为自己编写LDPC编译码程序的参考,因为matlab代码效率不高(The LDPC check matrix generation, the Gaussian elimination method and the BP decoding program can be used as the reference of the LDPC coding program, because the matlab code efficiency is not high.)

java推荐算法
java实现的几个推荐算法:slopeone SVD,RSVD,ItemNeighborSVD由于只是为了看看RMSE效果,因此很多功能都没完善如果需要跑起来看效果,那么你需要1. 下载movielens数据集,建议使用 1000W数据集 2. 查看修改regeneration.py 重新生成一遍数据集。再修改运行common下的DataConverter生成算法需要的格式3. 根据需要修改test目录里的代码,运行。参数配置可先不动,
