7. ML for Time Series with Prescience 7
8. Toy Use Case 8 We are going to have a look at the international airline passengers prediction problem. The initial data is in the csv format : steps passengers 1949-01 112 1949-02 118 1949-03 132 1949-04 129
9. Problem Definition Detection Time Series • Specific Target • Ground Truth quality • Specific Target • Ground Truth quality • Forecast • Anomaly detection • Prediction horizon • Forecast • Anomaly detection • Prediction horizon 9
10. Problem definition 10 What kind of problem do you want to solve ? • Simple Classification • Simple Regression • Time series classification • Time series regression/forecast
11. Problem definition 11 • What is your label ? • What is your ordering column ? Month Passengers 1949-01 112 1949-02 118 1949-03 132 1949-04 129 Ordering column Label
12. Problem definition 12 • How many steps forward do you want to predict ? One year => 12 steps • Do you want to apply a discount ? No => 1 • Scoring metric ? Default => MSE 1 Year
13. Experiment definition 13 How many fold do you want to create ? 2
14. Experiment definition 14 How much budget to allow on optimization ? 10
15. Demo 15
16. Scores are deceitful • Data Leakage – Unusable – Dangerous – Difficult to detect – Difficult to correct • Wrong problem definition 16
