mining algorithms, data modeling, and so on, as long as it is more than m of data, R is very difficult to do, But Python is basically competent. Add: Python has a dedicated data analysis package Pandas for SQL-like functions. However, Pandas loads all data into the memory.
seconds, it takes several hours for R to run, and 8 GB of memory is fully occupied ). In general, Python is a balanced language, which can be used in all aspects, while R is prominent in statistics. However, data analysis is not just about statistics, data collection, data processing, data sampling,

, the monthly variables accounted for the sum of the variables. With these cleaning and transformation work, we generate a dataset for modeling. (iv) Establishment of models. We choose the SAS EM Package as the modeling tool and choose the decision tree algorithm in the mining algorithm. The decision tree algorithm can handle hundreds of fields, has exploratory function and is highly automated. Considering

Scientific research direction: in universities, research units, enterprise research institutes and other high-level scientific research institutions to study the new algorithm efficiency improvement and future application. Second, talk about the skills required in each area of work.(1). Data

Text clustering, is a typical unsupervised machine learning method, the choice of clustering method depends on the data type. 3. Information extraction.4. Summary.5. Compress.Among them, text classification and clustering are the two most important and major mining functions.Mining Tools: 1.IBM DB2 Intelligent Miner. 2.

No installation is required and it is easy to use (idmer: Haha, everyone's favorite green version ). Like Yale, knime is developed in Java and can be extended using the mining algorithm in WEKA.

will not agree, because no matter the original database (IBM, Sybase, NCR, Oracle, Microsoft, etc ), the statistical analysis software (SAS, statistica, SPSS, etc), and even the reporting tools (Bo, Brio, Cognos, etc) are desperately extending their own value chains. Therefore, simply call Data Management (DM) to make sure that all data is in the world.As for
hundreds of models per year, data and model Management is very complex, data mining is expected to benefit very much, users have a good theoretical foundation and application level, you should choose powerful, flexible and efficient mining tools; otherwise, you should consider those features relatively simple, suite-s
