FeatureExtractor
内の extractFeature
samples
- The samples to extract the feature from.sampling_rate
- The sampling rate that the samples are encoded with.other_feature_values
- The values of other features that are needed to calculate this
value. The order and offsets of these features must be the
same as those returned by this class's getDependencies and
getDependencyOffsets methods respectively. The first indice
indicates the feature/window and the second indicates the
value.
java.lang.Exception
- Throws an informative exception if the feature cannot be
calculated.FeatureExtractor.extractFeature(double[],
