Deploying a Deep Learning Model to Classify Reviews in a Database

This workflow shows how a trained deep learning model can be used to classify new movie reviews in a database.

Read and preprocess new reviews Execute trained network and threshold Read dictionary and trained network Update values in database Please execute this workflow to add new reviews to the databaseNote: The workflow below will predict the sentiment for the new reviews and will delete the new reviews from the database. The new reviews with the predictedsentiment will be written into another table in the database.
