Read File Arff In C#
Reads the data without header according to the specified template. The data can be accessed via the getData method. Parameters: reader - the reader to use template - the template header lines - the lines read so far fieldSepAndEnclosures - an optional array of Strings containing the field separator and enclosures to use instead of the defaults.
The first entry in the array is expected to be the single character field separator to use; the remaining entries (if any) are enclosure characters to use. Throws: java.io.IOException - if something goes wrong See Also:. ArffReader public ArffReader(java.io.Reader reader, template, int lines, int capacity, java.lang.String. fieldSepAndEnclosures) throws java.io.IOException. Initializes the reader without reading the header according to the specified template.
The data must be read via the readInstance method. Parameters: reader - the reader to use template - the template header lines - the lines read so far capacity - the capacity of the new dataset fieldSepAndEnclosures - an optional array of Strings containing the field separator and enclosures to use instead of the defaults. The first entry in the array is expected to be the single character field separator to use; the remaining entries (if any) are enclosure characters to use. Throws: java.io.IOException - if something goes wrong See Also:. ArffReader public ArffReader(java.io.Reader reader, template, int lines, int capacity, boolean batch, java.lang.String. fieldSepAndEnclosures) throws java.io.IOException. Initializes the reader without reading the header according to the specified template. The data must be read via the readInstance method.
Parameters: reader - the reader to use template - the template header lines - the lines read so far capacity - the capacity of the new dataset batch - true if the data is going to be read in batch mode fieldSepAndEnclosures - an optional array of Strings containing the field separator and enclosures to use instead of the defaults. The first entry in the array is expected to be the single character field separator to use; the remaining entries (if any) are enclosure characters to use. Throws: java.io.IOException - if something goes wrong See Also:.

Convert to ARFF. 2 minutes to read. Contributors. In this article Converts data input to the attribute relation file format used by the Weka toolset Category: Module overview This article describes how to use the module in Azure Machine Learning Studio, to convert datasets and results in Azure Machine Learning to the attribute-relation file format used by the Weka toolset. This format is known as ARFF.
The ARFF data specification for Weka supports multiple machine learning tasks, including data preprocessing, classification, and feature selection. In this format, data is organized by entites and their attributes, and is contained in a single text file. You can find details of the Weka file format in the section. In general, conversion to the Weka file format is required only if you want to use both Azure Machine Learning and Weka, and intend to move your training data back and forth between them. For more information about the Weka toolset, see this Wikipedia article. Warning You cannot overwrite an existing ARFF file in Azure Storage.
How to use Convert to ARFF. Add the module to your experiment.
You can find this module in the category in Azure Machine Learning Studio. Connect it to any module that outputs a dataset.
