This is the configuration class to store the configuration of
a :class:`~openspeech.criterion.LabelSmoothedCrossEntropyLoss`.
It is used to initiated an `LabelSmoothedCrossEntropyLoss` criterion.
Configuration objects inherit from :class: `~openspeech.dataclass.configs.OpenspeechDataclass`.
Configurations:
criterion_name (str): name of criterion. (default: label_smoothed_cross_entropy)
reduction (str): reduction method of criterion. (default: mean)
smoothing (float): ratio of smoothing loss (confidence = 1.0 - smoothing) (default: 0.1)
