Regex and intent classification

PierreFG · August 7, 2019, 9:00am

Hi,

It’s written in the doc that REGEX are used in intent classification (after being processed in the regexfeaturizer). I’ve been searching in the code of the sklearn intent classifier and the embedding one but I’ve seen no trace of any use.

Any idea ?

Thank you, Pierre
