On GitHub, older generations have provided Python libraries for the conversion of files between the two formats, such as Liac-arff:https://github.com/renatopp/liac-arff. However, when the program is more complex, it is cumbersome to call so many external files, and these Arff libraries, when the attribute and the number of values inconsistent, will be error. So, with the support of my brother, I have writte

The ARFF file format used in WEKA is divided into two parts: header and data. The header is used to define the relation name and a series of attribute names and types, such: @RELATION iris @ATTRIBUTE sepallength NUMERIC @ATTRIBUTE sepalwidth NUMERIC @ATTRIBUTE petallength NUMERIC @ATTRIBUTE petalwidth NUMERIC @ATTRIBUTE class {Iris-setosa,Iris-versicolor,Iris-virginica} Data, as its name implies, is data. The attribute sequ

Here, the Arff file is an example of the Iris.arff file in the Data folder in the Weka installation directory.1. Convert the Arff file to a CSV file in Weka, and then delete the first line in the CSV file that describes the property name, such as.2, save, and put in the database data file directory (such as C:\ProgramData\MySQL\MySQL Server 5.5\data\weka);3, in navicat the corresponding database set up a da

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

The dataset is ADO. The central concept of net. Datasets can be treated as an in-memory database, which is a separate collection of data that is not dependent on the database.

It's common to know if a dataset is empty, but I'm starting to get a little vague on the concept of DS empty, and I looked at it online, and the results are as follows: The dataset is empty and there are no tables in the dataset.The dataset is empty, or a reference to a dataset type is null, meaning that the reference
