Class VowpalWabbitAdapter

java.lang.Object

org.dkpro.tc.ml.vowpalwabbit.VowpalWabbitAdapter

All Implemented Interfaces:

TcShallowLearningAdapter

public class VowpalWabbitAdapter
extends Object
implements TcShallowLearningAdapter

Using VowpalWabbit in DKPro TC: Depending on the learning and feature mode, a default configuration is used for regression, classification and sequence-classification, which can be overwritten by providing other parameters. All full list of all parameters that can be provided is here:

      https://github.com/VowpalWabbit/vowpal_wabbit/wiki/Command-line-arguments
 

Following default configurations are used:

 Classification (non-sequential): 
      --oaa = Use one-against-all multiclass learning
 
 Classification (sequential):
      --search_task = sequential
      --search_passes_per_policy = 2
      --cache = (a cache file is used)
      --search_history_length = 1

 the number of labels that have to predicted are determined in the backend automatically by DKPro TC.
