An example of discovering simple patterns using basic data mining
- 1. Data Mining Example ‘Tips’ dataset Irish Centre for High End Computing Dr. Eoin Brazil, Technology Transfer
- 4. Irish Centre for High End Computing (ICHEC) - Data Mining Example Large bins show global features, tips fall off quickly so perhaps this is not a very expensive restaurant.
- 5. Irish Centre for High End Computing (ICHEC) - Data Mining Example Smaller bins show local features, tips tend to be rounded to the nearest 50 cents or dollar.
- 6. Irish Centre for High End Computing (ICHEC) - Data Mining Example Looking at the correlation between variables (r) and checking to see who gives more or less than the ‘average’ tip of 18% of the bill.
- 7. Irish Centre for High End Computing (ICHEC) - Data Mining Example ‘ Conditioning’ or ‘Drilling down’ to explore more complex relationships within the data.
