Показать описание
In this video we learn about a very important object detection metric in Mean Average Precision (mAP) that is used to evaluate object detection models. In the first part of the video we try to understand how this method works and then move on to PyTorch to implement this from scratch.

Aladdin, Thank you. The first few minutes cleared up the thing that was stopping me from understanding mAP: I hadn't realized that Precison and recall were being calculated progressively. It's totally clear now.
