Mean Average Precision - Fun and Easy

How do you Measure Accuracy🎯 in Computer Vision? Well, we have created a comic that explains concepts such as Average Precision (mAP) and how you calculate it.

We used the topic of 🔫gun violence & mass shootings to not only draw awareness to the ongoing tragedies but also to start a discussion on how we can start reducing the occurrence of such events through technology🤖. Computer Vision is one such technology that can aid in an early warning detection system of weapons to alert authorities and help potential victims evade suspects in time.

==Topics discussed in this comic are as follows:==
✅ Confusion Matrix
✅ Intersection Over Union (IoU)
✅ Precision & Recall
✅ Mean Average Precision (mAP)
✅ Accuracy Curves

Confusion Matrix never made easy before .. the example of gun was really cleaver .

[ElfTRAVELTOUR]

Great comic! finally this confusion matrix is no more confusion!

[zakariaabderrahmanesadelao]

I watched this to relax, endee up understanding the whole concept... well done sir

[abcdasa]

great explanation. Tks for your afford!!!

[yuyuewang]

Ok thanks I understand, so why don’t we have AR average recall?

[Jobba]

At 4:36 it is told that the lower the IOU threshold, the lower the precision. Isn't it true that the confidence threshold is meant here instead of the IOU threshold, because the lower the IOU threshold the faster something is considered a TP

[dzsabulu]

Isn't the PR curve plotted by varying the SCORE/CONF threshold? (not the IOU threshold, as stated in the video)

[hassanharoon]

If various IOU Thresholds produce a PR-Curve then what is the significance of classification various thresholds? Is classification threshold (that controls the TP, TN, FP and FN) used anywhere?

[snkarbhr]

CV can never solution the gun Detection problem in school, because ML suffer with adversary attacks.
Only Right education and Spritual knowledge in school will solve human problems as it work directly on human intelligence.

Yours video was good and knowledgeable 👍👌

[mohammadyahya]

Thank you very much. Why please The higher the IoU the higher the recall:
