Chapter 18 Bosch Production Line Performance
This competition was hosted in 2016 by Bosch at https://www.kaggle.com/c/bosch-production-line-performance and was subtitled “Reduce manufacturing failures”
The price money was $30,000, the competition ended 11.11.2016 and 1373 teams had submitted a solution.
Challenge:
- Predict internal failures
- Data anonymized
- measurements
- tests
- measurements
- Benefit
- reduce manufacturing failures
The metric was Matthews correlation coefficient (MCC) between the predicted and the observed response. The MCC is given by:
\[MCC = score=\frac{\left(TP*TN\right) - \left(FP*FN\right) }{\sqrt{\left(TP*FP\right) \left(TP*FN\right) \left(TN*FP\right) \left(TN*FN\right)}} \] where:
- TP: number of true postive
- FP: number of false positive
- TN: number of true negative
- FN: number of false negative
The best possible score for perfect predictions is 1. The leader board look as follows:
- 0.52401
- 0.51847
- 0.51621
The winning solution is described in the next chapter
