Training and Testing a Customer Churn Predictor with KNIME and Snowflake
Training and Testing a Customer Churn Predictor with KNIME and SnowflakeThis workflow is an example of how to train a machine learning model in KNIME with data sampled from Snowflake. Once the model is applied at scale to the rest of the data in Snowflake to evaluate its reliability.Example data provided from kaggle: https://www.kaggle.com/becksddf/churn-in-telecoms-dataset 1. Data Preparation.Sample and filter data within Snowflake before loading it into a KNIME table. If you haven't executedthe 01b_Snowflake_ETL workflow before you can use the upper branch to create the" calls_contracts" table in Snowflake with example data. 2. Model Learning. Learns a Random Forest model and converts it into atransportable MOJO model. 3. Model Evaluation and Storing.Send the MOJO model to Snowflake and predict remainig data in the Snowflakedata table. The predicted and filtered result is read into KNIME to evaluate themodel acurracy.
