PräzisionRecall
PräzisionRecall is a concept used in information retrieval and machine learning to evaluate the performance of a system. It is a pair of metrics, precision and recall, that together provide a more nuanced understanding of a system's effectiveness than either metric alone.
Precision measures the proportion of retrieved items that are relevant. It answers the question: "Of all the
Recall, on the other hand, measures the proportion of all relevant items that were successfully retrieved by
The trade-off between precision and recall is a common consideration. Often, improving one metric can lead to
The PräzisionRecall curve is a graphical representation of this trade-off. It plots precision against recall for
