Package org.apache.ignite.examples.ml.knn

Class KNNRegressionExample

  • public class KNNRegressionExample
extends java.lang.Object
    Run kNN regression trainer (KNNRegressionTrainer) over distributed dataset.

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

    After that it trains the model based on the specified data using kNN regression algorithm.

    Finally, this example loops over the test set of data points, applies the trained model to predict what cluster does this point belong to, and compares prediction to expected outcome (ground truth).

    You can change the test data used in this example or trainer object settings and re-run it to explore this algorithm further.
