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

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!
