This workflow shows how to compute word embedding on a set of categorical variables with the granularity which allows them to be used as input of predictive models. A PCA Analysis is directly applied inside the component. I kept only a portion of embedding dimensions which caputures most of the variation, by doing so you can monitor model complexity. py package required: pandas gensim numpy nltk
