BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets. An advantage of Birch is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, Birch only requires a single scan of the database. In addition, Birch is recognized[1] as the, "first clustering algorithm proposed in the database area to handle noise (data points that are not part of the underlying pattern) effectively".

精通matlab6.5版_数值计算本章将花较大的篇幅讨论若干常见数值计算问题：线性分析、一元和多元函数分析、微积分、数据分析、以及常微分方程（初值和边值问题）求解等。但与一般数值计算教科书不同，本章的讨论重点是：如何利用现有的世界顶级数值计算资源 MATLAB。至于数学描述，本章将遵循“最低限度自封闭”的原则处理，以最简明的方式阐述理论数学、数值数学和 MATLAB计算指令之间的内在联系及区别。(matlab simulation)
