Two key reasons behind may be: (1) the slow gradient-based learning algorithms are extensively used to train neural networks, and (2) all the parameters of the networks are tuned iteratively by using such learning algorithms. Unlike these conventional implementations, this paper proposes a new learning algorithm called extreme learning machine (ELM) for single-hidden layer feedforward neural networks (SLFNs) which randomly chooses hidden nodes and analytically determines the output weights of SLFNs. In theory, this algorithm tends to provide good generalization performance at extremely fast learning speed. The experimental results based on a few artificial and real benchmark function approximation and classification problems including very large complex applications show that the new algorithm can p)

地震剖面显示源代码，用QT编写的程序，对地震数据显示感兴趣人员来说，有不错的借鉴意义。(Seismic profiles show the source code, programs written using QT, interested persons on the seismic data, there are a good reference.)

本系统是在asp版《在线文件管理器》的基础上设计制作，取其精华，弃其糟粕，功能更强，效率更高，具有以下特点： 1。采用三层结构开发，程序逻辑和用户界面彻底分离，可轻松换肤。 2。全部代码采用Ultra Edit编写，不使用任何可视化开发工具，精确控制代码流程，确保代码高效率运行。 3。自行开发自定义控件，不产生任何一丁点的HTML代码冗余。 4。尽可能的减少客户与服务器的交互，降低对服务器资源消耗，减少网络传输。 5。真正多用户系统，可分别为每个用户设置可管理的文件类型，目录等，上传的单个文件大小限制等。 6。各用户环境自由配置，风格自选（如果有多个风格的话），可自由设置每页显示的文件及目录数等。 7。文件与目录翻页分开，即使管理同一目录下的数万个文件也不再出现程序超时现象。 8。功能强大，除了asp版具备的全部功能如上传、下载、编辑、批量复制、移动、粘贴外还具备文件快速过滤搜索，智能修改文件属性。 9。效率极高。经测试，在一太普通PC上对一个包含50000个文件的目录进行浏览管理，任意翻页，执行时间均不超过1秒。过滤或者搜索则更是低至仅0.3秒的执行时间。而windows资源管理器打开目录或者asp版翻至最后一页都需要6.5秒甚至更长时间。-the system is the asp edition of "online document management device" on the basis of the design, select the essence and disposable dross, more powerful, more efficient and has the following features : 1. The development of a three-tier structure, procedures and user interface logic completely separated easily Eurocargo. 2. All the code used Ultra Edit preparation, not the use of any visual development tools, precision flow control code, the code to ensure
