This document outlines the steps in the data science process from raw data to deployment using KNIME. It begins with an overview of the CRISP-DM process and then discusses each step in more detail, including data preparation, model training, optimization, evaluation, and deployment. It then provides an example classification problem using airline departure delay data and outlines challenges for participants to work through in data access/preparation, model training/optimization, and deployment. Contact information is also provided for KNIME resources.

Data Exploration
• Sometimes in between Data Access and Data
Preparation there is a Data Exploration phase
• The Data Exploration phase is useful to get to
know the data
• KNIME offers a few visualization nodes to build
dashboards to explore the data

Classification Problem & Data Set
• Airline Dataset: http://stat-computing.org/dataexpo/2009/the-data.html
• Smaller dataset (Jan 2007) (AirlineDataset.table)
• Challenge:
Predict Departure Delays
If on original airline dataset, only flights from airport ORD
Output Class = “delay” if depdelay > 15min
otherwise “no delay”
Input features all what is available and more if you can find it!
