Enum Constant Summary

distribution
The method described in: D.

ratio
Retains only features whose distance from the closest visual word is at least b times smaller than their distance from the second closest visual word.

std
Retains only features whose distance from the closest visual word is at least a standard deviations smaller than the mean distance of this feature from all visual words.

Method Detail

values

public static VladAggregatorWithFiltering.FilteringMethod[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (VladAggregatorWithFiltering.FilteringMethod c : VladAggregatorWithFiltering.FilteringMethod.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static VladAggregatorWithFiltering.FilteringMethod valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
