8. Model Overview Recorded Journeys Real-Time Prediction Range Prediction Journey Prediction Real-Time Data
9. Car Data Collection Data Streaming Data Science Batch Training Real-Time Prediction Dashboard Field Engineering Architecture Backend Data Processing Data Serving
10. 1.  Clustering of recorded journeys
11. Recorded Journeys
12. Clustering of Journeys Cluster End Cluster Start
13. Clustering of Journeys Cluster Start “Hofbräuhaus Cluster” Single Journeys belonging to this cluster
14. Clustering of Journeys Cluster End “Hofbräuhaus Cluster” Single Journeys belonging to this cluster
15. 2.  Initial classification of journey cluster
16. Initial Classification
17. Initial Classification
18. 3.  Online classification of journey cluster
19. Online Classification Performance Ÿ  Leave-one- journey-out- cross-validation Ÿ  The longer the drive, the more accurate the prediction becomes • • • • • • • • • • • 0.05 0.10 0.15 0.20 0.25 0 1 2 3 4 5 6 7 8 9 10 Minute Median Log−Loss
