Class Step_4_Add_age_fare

  • public class Step_4_Add_age_fare
extends java.lang.Object
    Add yet two numerical features "age", "fare" to improve our model over Step_3_Categorial.

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

    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.
