multiple classification models in a certain order, the there is a dependency between them, and each subsequent model requires a comprehensive performance contribution from the existing model, - build a more powerful classifier from several weaker classifiers, such as a gradient-boosting decision tree - The decision tree of the prefect forest is set up to minimize the errors of the adult in fitting data. - + The following will compare the predictions of a decision tree with a single de

Are you talking about typed dataset and untyped dataset? Typed Dataset is derived from dataset. It generates a dataset Based on the predefined data schema and imposes a strong type constraint on fields in the dataset. You can see

Take the table name "MyTable" and the field FirstName varchar (30) and FamilyName varchar (30) as an example. Non-strong (UnTyped) Dataset does not need to define the attributes of each field of the corresponding table in advance, you can directly obtain the values from the queried result set (non-strong (UnTyped) Dataset), for example:String lFirstName =LDs. Table ["MyTable"]. Rows [0] ["FirstName"]. ToStr

I have seen many such comments on the Internet,AccessThe performance of Typed Dataset data is higher than that of untyped dataset. I have always been skeptical. After all, both are implemented based on DataSet. The former isCodeDetermine the structure when writing. The latter is determined at runtime. The efficiency of the two operations after instantiation is th

A dataset, also known as a data set, data set, or data set, is a collection composed of data. A Data Set (or dataset) is a collection of data, usually in the form of tables.
