This evaluation is for the sequences Uniconcourse, Gardenspoint and campusloop datasets only. Please refer to the arxiv document's figure 12. In this dataset there is a traversal of the same path 2 times (referred to as live (1st traversal) and memory (second traversal).
Thanks for reply! But I wonder if its convenient to provide evaluation code? It seems that your code in https://github.com/mpkuse/cartwheel_train cannot generate such pr-curve in the paper.
Hi eddy, actually that code is a mess. It is easiest to implement it yourself. Perhaps this could help you a bit: https://github.com/mpkuse/vins_mono_debug_pkg/blob/master/src_place_recog/place_recog_analysis_tool.py
Basically I set various thresholds and record the precision-recall and plot it myself later.
Hi, Thanks for your great job again, but Im still confusing about how to get validation metric... More specifically, I cannot understand above sentence in your paper.
What is the defination of "positive matches"? Is it the correct matches? What is the defination of "length of the sequence", and how is it used in finall P-R curve?
Currently I know the PR curve is defined to adjusting a threshold of matching score to get specific precision and recall metrices and record their value to form a curve.
To get a PR curve, two sequence should be the input, one (LABEL) is the labels and the other is score of every element (SCORE, what algorithms estimated). In CARL, matches whose index is within six indices of itself is labeled as 1 and others are labeld as 0, and the matching scores become second input (SCORE). Could you please explain if there is any difference between your paper and CALC?
Your reply will be higly appreciated!
