• How to update efficiently a table that contains a prediction model based on DTM (Document Term Matrix)?

  Hello! I work on textual data classification. So I made a model that predicts the class by taking as input the DTM. Now, I would like to update, in a regular and efficient way, the data table with new rows. My problem is to be able to easily compute the DTM using a formula so that the update is automatic. Here is a file based on the example of potato chip reviews:
