代码说明:

  matlab编写的文本分类的程序,可以对已经分好词的文本进行分类,先自己导入数据,用libsvm中的svm进行分类和预测,特征用tfidf算法,还利用卡方检验进行了特征选择,可自行设定阈值。(matlab prepared text classification program, you can have a good word of text classification, classification and prediction using libsvm in svm, characterized by tfidf algorithm, also used the chi-square test was used for feature selection, you can set thresholds on their own.)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    这个方法有两个好处。 ( a )虽然只是一个半径差逼近,很容易找到最高在一个小蓄电池,因为通过降低 隐平滑做的蓄电池。( b )在同一时间处理时间搜索减少 (Pattern Recognition and Image Procesing Group. The size of the accumulator is varied as hierarchical voting is performed. This has two advantages. [a] While the radius is only a poor approximation, it is easier to find the maximum in a small accumulator and because by means of the downsampling implicit smoothing is done to the accumulator. [b] At the same time processing time for the search is reduced.)

    负责火星的一个低轨道空间站的设计。为简化结构,该空间站由一系列密闭的立方体(airtight cubical modules ACM)组成,这些ACM曾连接在一起。困扰你的一个问题是致命的病菌也许留在火星的上层大气中。因为空间站有时需要在上层大气中飞行,所以急需在ACM的各个接触面进行额外的防护,无论是边对边还是面对面,连接是密闭的,所以没有细菌能够进入。一个ACM与另外一个ACM共享的面不需要防护。如果在每个ACM每个面上都加防护,花费巨大。因此,需要知道ACM额外防护的确切面数目(Responsible for the design of a low-orbit space station on Mars. In order to simplify the structure of the space station by a series of closed cubes (airtight cubical modules ACM) composed of these ACM had together. One problem is bothering you deadly germs might stay in the upper atmosphere of Mars. Because the station is sometimes necessary to fly in the upper atmosphere, so urgently needed in all contact surfaces of the ACM additional protection, either face to face or side-to-side, the connection is closed, so no bacteria can enter. An ACM ACM shared with another surface does not need protection. If you have added protection on each side of each ACM, costly. Therefore, the need to know the exact number of additional surface protection ACM)
