Boosting is a meta-learning approach that aims at combining an ensemble of weak classifiers to form a strong classifier. Adaptive Boosting (Adaboost) implements this idea as a greedy search for a linear combination of classifiers by overweighting the examples that are misclassified by each classifier. icsiboost implements Adaboost over stumps (one-level decision trees) on discrete and continuous attributes (words and real values). See http://en.wikipedia.org/wiki/AdaBoost and the papers by Y. Freund and R. Schapire for more details [1]. This approach is one of most efficient and simple to combine continuous and nominal values. Our implementation is aimed at allowing training from millions of examples by hundreds of features in a reasonable time/memory.

Quaternions are hypercomplex numbers (that is generalizations of the complex numbers to higher dimensions than two). For an introduction, refer to the wikipedia article on Quaternions. Quaternion toolbox for Matlab® extends Matlab® to allow calculation with matrices of quaternions in almost the same way that one calculates with matrices of complex numbers. This is achieved by defining a private type to represent quaternion matrices and overloadings of many standard Matlab® functions. The toolbox supports real and complex quaternions (that is quaternions with four real or complex components).

The GIFT (the GNU Image-Finding Tool) is a Content Based Image Retrieval System (CBIRS: http://en.wikipedia.org/wiki/CBIR). It enables you to do Query By Example (QBE: http://en.wikipedia.org/wiki/QBE) on images, giving you the opportunity to improve query results by relevance feedback. For processing your queries the program relies entirely on the content of the images, freeing you from the need to annotate all images before querying the collection.

Boost C++ Libraries Free peer-reviewed portable C++ source libraries Boost C++ Libraries 基本上是一個免費的 C++ 的跨平台函式庫集合，基本上應該可以把它視為 C++ STL 的功能再延伸；他最大的特色在於他是一個經過「同行評審」（peer review，可參考維基百科）、開放原始碼的函式庫，而且有許多 Boost 的函式庫是由 C++ 標準委員會的人開發的，同時部分函式庫的功能也已經成為 C++ TR1 (Technical Report 1，參考維基百科)、TR2、或是 C++ 0x 的標準了。 它的官方網站是：http://www.boost.org/，包含了 104 個不同的 library；由於他提供的函式庫非常地多，的內容也非常地多元，根據官方的分類，大致上可以分為下面這二十類： 字串和文字處理（String and text processing） 容器（Containers） Iterators 演算法（Algorithms） Function objects and higher-order programming 泛型（Generic Programming） Template Metaprogramming Preprocessor Metaprogramming Concurrent Programming 數學與數字（Math and numerics） 正確性與測試（Correctness and testing） 資料結構（Data structures） 影像處理（Image processing） 輸入、輸出（Input/Output） Inter-language support 記憶體（Memory） 語法分析（Parsing） 程式介面（Programming Interfaces） 其他雜項 Broken compiler workarounds 其中每一個分類，又都包含了一個或多個函式庫，可以說是功能相當豐富。

Fire and Fury。 This article is about the 2018 book. For other uses, see Fire and Fury (disambiguation). The title refers to a quote by Trump about the conflict with North Korea. The book became a New York Times number one bestseller.Fire and Fury: Inside the Trump White House is a 2018 book by Michael Wolff which details the behavior of U.S. President Donald Trump and the staff of his 2016 presidential campaign and White House. The book highlights descriptions of Trump's behavior, chaotic interactions among senior White House staff, and derogatory comments about the Trump family by former White House Chief StrategistSteve Bannon. Trump is depicted as being held in low regard by his White House staff, leading Wolff to state that "100% of the people around him" believe Trump is unfit for office.[1] Reviewers generally accepted Wolff's portrait of a dysfunctional Trump administration, but were skeptical of many of the book's most controversial claims.

第一部分：什么是SPI SPI是一种在FPGA和其他芯片之间传输数据的简单有效的接口方式.SPI是允许一个器件同其他一个或多个器件进行通讯的简单接口。SPI是什么样的？首先让我们来看看两个芯片之间的S P 1接口是如何连接的。在两个芯片时间通讯时，SPl需要4条连线。正如你所看到的，他们是SCK，MISO，MOSI以及SSEL，其中一个芯片叫做主控芯片，另一个叫从芯片。SPI基础http://en.wikipedia.org/wiki/Serial_Peripheral Interface_Bus基本特点：1.同步2.串行3.全双工4·非即插即用5.一主多从更多细节：1，同步时钟有主控芯片产生，每个时钟传输一位数据2，数据在传输前，首先许要进行并转串，才能用一条线传输3，两条数据线，一条输入、一条输出4主从双方有关于SPI传输的先验知识，如比特顺序、数据长度等5，数据传输有主控芯片发起，每次只与一个从芯片通讯
