Precision recall curve

Parent: Loop closure detection Source: cometlabs

• used to better quantify the performance (balance between false positives and false negatives in loop closure detection )
• highlights tradeoff between precision and recall
  • precision (absence of false positives) but may lead to the appearance of false negatives
  • recall (prediction power)
• e.g. tweaking to improve recall
  • increases sensitivity to similarities in the image
  • thus increases possibility of false positives
