• AUPRC is same as AUC Score but for Precision Recall Curve (PRC).
• It gives only one score which gives the area under the PRC curve
• Greater the AUPRC score, better the model
• AUPRC Score is calculated from Precision and Recall
  • For different threshold, the Precision and Recall is plotted on the graph
  • All the point will be connected by a line
  • And the score is the Area Under the Curve of that line
• Range: $[0,1]$
• If you need to find best threshold, then use Precision Recall Curve (PRC), ROC Curve
