决策树癌症预测 使用现有数据通过决策树进行学习来预测乳腺癌的示例（scikit-learn / python） 加工 收集的数据样本已分为测试样本和训练样本。 使用scikit的决策树生成器和转换集，可用于基于ID3生成树。 然后可以将测试数据用于交叉验证生成的树的准确性。 这个小程序还生成pdf，以可视化生成的树。 注意 该程序仅用于演示/实验目的。 以下是依赖项 python numpy scipy scikit-学习pydotplus graphviz 使用说明 安装python版本2.7 要安装上述软件包，请遵循以下命令 点安装numpy 点安装scipy 点安装scikit学

原版pdf效果极差，网上也找了些由epub格式转换过来的，排版不调整就直接发布，一点也不负责。自己动手丰衣足食吧

The methodology used to construct tree structured rules is the focus of this monograph. Unlike many other statistical procedures, which moved from pencil and paper to calculators, this text's use of trees was unthinkable before computers. Both the practical and theoretical sides have been developed in the authors' study of tree methods. Classification and Regression Trees reflects these two sides, covering the use of trees as a data analysis method, and in a more mathematical framework, proving some of their fundamental properties.

TheSparksFoundation_Task-4_Decision-Trees 决策树是用于分析数据的图形表示。 决策树以这种方式为我们提供数据，我们可以轻松地读取，理解和分析数据。 决策树算法属于监督学习算法家族。 ...使用决策树的目的是创建一个训练模型，该模型可以通过学习从先前数据（训练数据）推断出的简单决策规则来预测目标变量的类或值

Behavior Designer最新版1.6.6 - Behavior Trees for Everyone

基于行为树的编程方法，可以和强化学习无缝结合，比状态机更好用，值得学习

String algorithms are a traditional area of study in computer science. In recent years their importance has grown dramatically with the huge increase of electronically stored text and of molecular sequence data (DNA or protein sequences) produced by various genome projects. This 1997 book is a general text on computer algorithms for string processing. In addition to pure computer science, the book contains extensive discussions on biological problems that are cast as string problems, and on methods developed to solve them. It emphasises the fundamental ideas and techniques central to today's applications. New approaches to this complex material simplify methods that up to now have been for the specialist alone. With over 400 exercises to reinforce the material and develop additional topics, the book is suitable as a text for graduate or advanced undergraduate students in computer science, computational biology, or bio-informatics. Its discussion of current algorithms and techniques also makes it a reference for professionals.

非影印版，可以不用OCR 直接复制文字，之前在CSDN上找到影印版居然要12个资源分，嗯，我决定把分数挣回来
