I can (and have) go on and on about the treachery of messy/bad datasets. Though its substantially less exciting than… pretty much everything else, I believe (proportional to the heartache and stress it causes) we don’t spend enough time talking about it or building solutions around it. No matter how new and fancy your ML algorithm is, it’s success is predicated upon a properly sanitized dataset. If you are using bad data, your approach will fail—either flagrantly (best case), or unnoticeably (considerably more probable and considerably more pernicious).
