Precision recall area under the curve
WebApr 2, 2015 · Dear Rahman, AUC is a Area Under ROC curve. 1) First make a plot of ROC curve by using confusion matrix. 2) Normalize data, so that X and Y axis should be in unity. Even you can divide data values ... WebWhen a relevant document is not retrieved at all, the precision value in the above equation is taken to be 0. For a single information need, the average precision approximates the area under the uninterpolated precision-recall curve, and so the MAP is roughly the average area under the precision-recall curve for a set of queries.

WebApr 7, 2024 · 1 Answer. When the threshold is very high, with only very few instances predicted as positive, the precision is around 0.5. The recall is very low, since only a small proportion of positive instances is captured. As the threshold decreases a little, first precision decreases because mostly False Positive (FPs) are included. WebSep 20, 2024 · AUC-PR stands for area under the (precision-recall) curve.
