variety of preprocessing means To increase the quality of the data to a certain height. So the question is, how do you do data exploration?As I said before, you need to explore data types and data quality, and then use two tools to explore the data, IBM SPSS Modeler for commercial data mining software, and the Python language.IBM SPSS Modeler is now an IBM Data Mining tool that enables data mining modeling

It should be this time last year, I started to get into the knowledge of machine learning, then the introductory book is "Introduction to data mining." Swallowed read the various well-known classifiers: Decision Tree, naive Bayesian, SVM, neural network, random forest and so on; In addition, more serious review of statistics, learning the linear regression, but also through Orange, SPSS, R to do some classification prediction work. But the external sa

an understandable way.The three main elements of data mining are:>Technologies and algorithms:Currently, common data mining technologies include --Auto Cluster Detection)Decision tree (demo-trees)Neural Networks)>Data:Because data mining is a process of mining unknown in known conditions,Therefore, we need to accumulate a large amount of data as a data source.The larger the volume, the data mining tool will have more reference points.>Prediction Model:That is, the business logic for data mining

must know whether the two population variance (variances) is equal. The T-test value is calculated based on whether the variance is equal. That is to say, t-test depends on the variance of variances. Therefore, while performing t-test for equality of means, SPSS must also perform Levene's test for equality of variances. 1. in the Levene's test for equality of variances column, the F value is 2.36, Sig. is. 128 indicates that there is "no significant

own situation, he decided to focus on distributed machine learning. The specific plan is as follows: I. Preparations 1. Focus on mahout. Note: Machine learning is a very complicated problem. It is definitely not just a few tools that can be done, because machine learning is based on mathematics and cannot do well in mathematics. However, considering the actual situation, you can only learn distributed machine learning while laying the foundation. 2. Learn about the hadoop ecosystem and big data

Clustering Analysis is a widely used Analysis Method with many algorithms. Currently, analysis tools such as SAS, Splus, SPSS, and SPSS Modeler support clustering analysis, especially in online game data analysis, the role is still very great, especially when we analyze certain customer groups, exclude interference from human grouping, it is important to objectively and comprehensively display the character

speed of data, they started looking for more innovative ways to use the data.2. Are you sure you want the eggs to touch the stone?"All right, but why do I need new tools? Can't I use the original software tools to analyze big data?" We're talking about using Hadoop to arrange hundreds of thousands of unstructured data inputs. In the discussion, a listener asked why he could not simply use SPSS to analyze a large number of text corpora. In fact, once
