一维褶积 雷克子波与地层序数 地震资料正演方法(One-dimensional convolution Ricker wave formation ordinal)

VC++实现 multiview多视图窗口的实例源代码，可看到打开窗体时有几个子窗体随主窗口一起打开，如果你不知道这是怎么创建的，那么你需要本源码为你提供参考。源码在VC6.0下可顺利编译。如果初次编译有误，你可重新编译一下即可正常。(VC++ implementation source code examples multiview multi-view window, you can see there are several sub-forms together with the main window opens, if you do not know how to create, then you need to provide a reference for the source when you open the form. Source code can be compiled successfully under VC6.0. If the initial compilation is incorrect, you can recompile to normal.)

tf–idf, short for term frequency–inverse document frequency, is a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus.[1]:8 It is often used as a weighting factor in information retrieval and text mining. The tf-idf value increases proportionally to the number of times a word appears in the document, but is offset by the frequency of the word in the corpus, which helps to control for the fact that some words are generally more common than others. Variations of the tf–idf weighting scheme are often used by search engines as a central tool in scoring and ranking a document s relevance given a user query. tf–idf can be successfully used for stop-words filtering in various subject fields including text summarization and classification. One of the simplest ranking functions is computed by summing the tf–idf for each query term many more sophisticated ranking functions are variants of this simple model.
