Weighted precision at a glance

• Description: Weighted mean of precision with weights equal to class probability
• Default thresholds: Lower limit = 80%
• Default recommendation:
  • Upward trend: An upward trend indicates that the metric is improving. This means that model retraining is effective.
  • Downward trend: A downward trend indicates that the metric is deteriorating. Feedback data is becoming significantly different than the training data.
  • Erratic or irregular variation: An erratic or irregular variation indicates that the feedback data is not consistent between evaluations. Increase the minimum sample size for the Quality monitor.
• Problem type: Multiclass classification
• Chart values: Last value in the timeframe
• Metrics details available: Confusion matrix

Do the math

Precision (P) is defined as the number of true positives (Tp) over the number of true positives plus the number of false positives (Fp).

                            number of true positives
Precision =  ________________________________________________________

             number of true positives + the number of false positives
