I only need one question to have 80% the pb is that I tried a lot of solutions and no thing work ,

thanks a lot.

@gitosam did you make it with week 3 I am also stack in the quiz

yes @gsoumia

[gsoumia]

@gitosam could you help me with juste one question please?
either that :
Consider face detector have Miss rate 0.40 for FPPI = 10^-1. We are working with dataset that has 5 faces on each image in average. What Precision and Recall corresponds to this parameters? Enter precision and recall values in percentages with space:

or that one:
We work with video of size 1024x768 pixels and 25 fps. We use sliding window object detector with window size 20x20 pixels and stride 2, 1 image scale (i.e. without pyramid). What should be false positive rate of the detector s.t. detector output false positive less frequently than 1 time per second? Round answer with 1e-07 precision.

Answer: 97 60

[gsoumia]

Thanks a lot I will try it actually I was sur about 90 60 could you explain the answer to me please?
I know that: precision is 1 - FPPI and recall is 1 - miss rate

[gitosam]

@gsoumia
FPPI = FP/ no. of images(N)=0.1
Ground truth = 5N
TP = recall * 5N = 0.6 * 5N = 3N
Percision = TP/(TP + FP) = 3N/(3N+0.1N)=3/3.1N = 0.9677
i hope this will help..

[gsoumia]

thanks a lot

[gitosam]

You're welcome.
