Combination of data mining and financial engineering -- ariszheng Recently, a math expert asked me how to combine data mining and financial engineering? Which books are good tutorials? I am also a beginner. In my philosophy, the combination of data

both range, but also to calculate the ratio. For example, age is the ratio, 20 years old than 30 years old young 10 years old, can also ask for the mean value of age.Data types In addition to this classification there are other classifications, but such classification is the basic classification, mastered can be status quo. The quality of the data is mainly: Missing attribute values, object duplication, outliers, inconsistent

Before we saw the data and the preprocessing of the data, where was the data after processing? Put it in a place called "Data Warehouse".Basic concepts of data warehousing: Definition of Data Warehouse-topic-oriented, int

integration, Data transformation, data specification, etc. This section is interested in reading a book, "Python Data analysis and mining". The book looks like a frame. In fact, it doesn't write well. I wasted a long time.Six Modeling machine learningLearn a variety of machine learning,

Common Data Mining Methods Common methods for data analysis using data mining include classification, regression analysis, clustering, association rules, features, change and Deviation Analysis, and Web page mining, they mine

Chapter 3 issues Data mining is not easy because the algorithms used become very complex and data is not always available in one place. It needs to be integrated from a variety of heterogeneous data sources. These factors also cause problems. In this tutorial, we will discuss the main issues:

original data Overview of Data Protocol policies Dimensional regression Quantity specification Data compression Wavelet transform--linear signal processing technology, suitable for high dimensional data (HTTP://HI.BAIDU.COM/QINGSHUANGCII/ITEM/31E8831E65350DDE64EABF4C)
