Package org.apache.ignite.examples.ml.preprocessing.encoding

Class LabelEncoderExample

  • public class LabelEncoderExample
extends java.lang.Object
    Example that shows how to use Label Encoder preprocessor to encode labels presented as a strings.

    Code in this example launches Ignite grid and fills the cache with test data (based on mushrooms dataset).

    After that it defines preprocessors that extract features from an upstream data and encode string values (categories) to double values in specified range.

    Then, it trains the model based on the processed data using decision tree classification.

    Finally, this example uses Evaluator functionality to compute metrics from predictions.
