Based on the characteristic engineering, the user characteristic, combined with the related machine learning algorithm, is used in the field of accurate delivery, forecast, wind control and so on. Whether there is supervised learning classification algorithm or unsupervised clustering, it is necessary to establish feature vectors to preprocess the features, and in the supervised training, sample screening is required. This section explains some of the

Classification algorithm and our life is closely related to the current data mining is the most widely used algorithms, such as: The known series of temperature, humidity sequence and the history of the statistics, we need to use historical data as a learning set to determine whether tomorrow rain, and bank credit card fraud discrimination.Classification problem

Unlimited classification: queries data from databases and recursively sorts data in arrays. Unlimited classification: query data from the database and perform custom sorting recursively in the array. it also realizes that there are many deficiencies and the processi

the data of the Internet system can be classified into the following 3 categories:1, core business data: such as user order form, merchant order form2, user-related data: User basic information, avatar, profile, hobbies, etc.3, configuration information: Database configuration, sub-Library table configuration, etc. If all of the above

Classification of Data Center reconstruction systems and data center reconstruction Systems During this time, I was truly on the machine room. After constantly overcoming the feeling that I was not satisfied with the VB. NET language, I finally had a very intuitive understanding of the reconstruction of the individual data
