Interface FeatureExtractFns.ExtractFn<InputT,VectorT>

Type Parameters:

InputT - type of the input to feature extraction.

VectorT - type of feature extraction result.

All Known Subinterfaces:

FeatureExtractFns.BatchExtractFn<InputT,VectorT>

Enclosing interface:

FeatureExtractFns

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface FeatureExtractFns.ExtractFn<InputT,VectorT>

Generic feature extraction function, takes multiple raw input and should return extracted features of user defined type.
