Method Detail

fixed

public static HyperParamValues<Double> fixed(double fixedValue)

range

public static HyperParamValues<Double> range(double min,
                                             double max)

around

public static HyperParamValues<Double> around(double value,
                                              double step)

fixed

public static HyperParamValues<Integer> fixed(int fixedValue)

range

public static HyperParamValues<Integer> range(int min,
                                              int max)

around

public static HyperParamValues<Integer> around(int value,
                                               int step)

unorderedFromValues

public static <T> HyperParamValues<T> unorderedFromValues(Collection<T> values)

fromConfig

public static HyperParamValues<?> fromConfig(com.typesafe.config.Config config,
                                             String key)

Parameters:

config - application configuration

key - config key to access

Returns:

a HyperParamValues appropriate to the value. If an int or double, returns fixed(int) or fixed(double) respectively. If a List<int> or List<double>, returns range(int,int) or range(double,double) respectively.

chooseHyperParameterCombos

public static List<List<?>> chooseHyperParameterCombos(List<HyperParamValues<?>> ranges,
                                                       String hyperParamSearch,
                                                       int howMany)
