ArffTools

.NET library for reading and writing Weka attribute-relation file format (ARFF) files

NuGet license

Features

  • Read and write ARFF files
  • Supports relational attributes
  • Supports sparse instances
  • Supports instance weights
  • Proper quoting and escaping of special characters

Usage

Reading ARFF files:

using (ArffReader arffReader = new ArffReader("glass.arff"))
{
    ArffHeader header = arffReader.ReadHeader();
    while (arffReader.ReadInstance() is object?[] instance)
    {
        // process instance
    }    
}

Reading all instances at a time:

object?[][] instances = arffReader.ReadAllInstances();

Writing ARFF files:

using (ArffWriter arffWriter = new ArffWriter("iris.arff"))
{
    arffWriter.WriteRelationName("iris");
    arffWriter.WriteAttribute(new ArffAttribute("sepallength", ArffAttributeType.Numeric));
    arffWriter.WriteAttribute(new ArffAttribute("sepalwidth", ArffAttributeType.Numeric));
    arffWriter.WriteAttribute(new ArffAttribute("petallength", ArffAttributeType.Numeric));
    arffWriter.WriteAttribute(new ArffAttribute("petalwidth", ArffAttributeType.Numeric));
    arffWriter.WriteAttribute(new ArffAttribute("class", ArffAttributeType.Nominal("Iris-setosa", "Iris-versicolor", "Iris-virginica")));
    arffWriter.WriteInstance(new object?[] { 5.1, 3.5, 1.4, 0.2, 0 });
}

Instances are represented as object?[] whose elements correspond to the attribute values. ARFF attribute types are mapped to .NET types as follows:

ARFF attribute type .NET type
numeric, integer, real double
nominal int
string string
date DateTime
relational object?[][]

Missing values are represented as null. Sparse instances are represented as normal (dense) instances in memory.
