Quick Start

Basic Regression

using VW;

using (var vw = new VowpalWabbit("--quiet"))
{
    vw.Learn("1 | feature1 feature2");
    vw.Learn("0 | feature3 feature4");

    var prediction = vw.Predict("| feature1 feature2");
}

Contextual Bandits (CB ADF)

using VW;

using (var vw = new VowpalWabbit("--cb_explore_adf --quiet"))
{
    var example = @"shared | user_age:25
        | action1 sport
        | action2 politics
        | action3 music";

    vw.Learn(example);
    var prediction = vw.Predict(example);
}

Save and Load Models

using (var vw = new VowpalWabbit("--quiet"))
{
    // ... train ...
    vw.SaveModel("model.vw");
}

using (var vw = new VowpalWabbit("--quiet -i model.vw"))
{
    var prediction = vw.Predict("| feature1 feature2");
}
