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.

第一部分：什么是SPI SPI是一種在FPGA和其他芯片之間傳輸數據的簡單有效的接口方式.SPI是允許一個器件同其他一個或多個器件進行通訊的簡單接口。SPI是什么樣的？首先讓我們來看看兩個芯片之間的S P 1接口是如何連接的。在兩個芯片時間通訊時，SPl需要4條連線。正如你所看到的，他們是SCK，MISO，MOSI以及SSEL，其中一個芯片叫做主控芯片，另一個叫從芯片。SPI基礎http://en.wikipedia.org/wiki/Serial_Peripheral Interface_Bus基本特點：1.同步2.串行3.全雙工4·非即插即用5.一主多從更多細節：1，同步時鐘有主控芯片產生，每個時鐘傳輸一位數據2，數據在傳輸前，首先許要進行并轉串，才能用一條線傳輸3，兩條數據線，一條輸入、一條輸出4主從雙方有關于SPI傳輸的先驗知識，如比特順序、數據長度等5，數據傳輸有主控芯片發起，每次只與一個從芯片通訊
