word_error_rate
(input: Union[str, List[str]], target: Union[str, List[str]]) Tensor [source]¶ Compute the word error rate of the predicted word sequence(s) with the reference word sequence(s). Its class version is
torcheval.metrics.WordErrorRate
.Parameters: - input (str, List[str]) – Predicted word sequence(s) to score as a string or list of strings.
- target (str, List[str]) – Reference word sequence(s) as a string or list of strings.
Examples
>>> import torch >>> from torcheval.metrics.functional import word_error_rate >>> input = ["hello world", "welcome to the facebook"] >>> target = ["hello metaverse", "welcome to meta"] >>> word_error_rate(input, target) tensor(0.6) >>> input = ["this is the prediction", "there is an other sample"] >>> target = ["this is the reference", "there is another one"] >>> word_error_rate(input, target) tensor(0.5)
