Sometimes we often encounter in the actual classification data mining, the class sample is very uneven, the direct use of this unbalanced data will affect the classification of some models, such as the logistic REGRESSION,SVM, a solution is to balance the data sampling, here provides a recommended code implementation , the input and output data formats are required as label+tab+features, such as LIBSVM formatUsage:Usage: {0} [options] DataSet Subclass

Basic concepts The official document in TensorFlow describes the dataset data object in this way: A dataset can be used to represent a collection of input pipeline elements (a nested structure of tensor) and a "logical plan" for translating these elements into action. In a dataset, an element can be a vector, tuple, or dictionary form.In addition, the

Chapter 6 What is a datasetDelphi 4 has four types of Standard dataset components: tTable, tquery, tstoredproc, and tclientdataset. These dataset components are inherited from a common basic class tdataset, where only tclientdataset is inherited directly from tdataset, while tTable, tquery, and tstoredproc are directly inherited by tdbdataset, the upper level of tdbdataset is tbdedataset, and that of tbdeda

The dataset stores data in the disconnected cache. The structure of a dataset is similar to that of a relational database. It exposes hierarchical object models of tables, rows, and columns. In addition, it contains the constraints and relationships defined for the dataset.Source: http://msdn.microsoft.com/library/chs/default.asp?

Aspire is a RAD tool that provides users with a standard xml/xsl, Java EE, and relational database technology to quickly create a Web site. The Aspire acceptable sources include stored programs, SQL statements, EJBS, and Java controls, and use Apache's Xerces/xalan as the converted processor. Aspire can be used for a variety of servlet engines, such as Apache/jserv, Apache/tomcat, and WebSphere. The current development features include a consolidated interface for reporting tools such as Cryst

When we merge two identical or similar dataset objects in ADO. NET, we typically use the dataset's Merge method, which has multiple overloaded versions, and we review the merge method before introducing it, and here's how to use the merge method in MSDN: The merge method is used to consolidate two DataSet objects that are roughly similar to the schema . Merging on a client application is typi

Because of the two principles, the dataset's reputation has been badly screwed up. First, it is inconvenient to use an XML-serialized dataset to interact with other non-. NET code. If the dataset is used in the Web Services API, it is not used with the other. NET Framework, it can be very difficult to interact with the system. Second, it is a very general container. You can cheat by cheating. NET Framework,
