The article discusses the debates surrounding the development process at Ground Zero in New York City, the site where the World Trade Center once stood. The author argues that the rebuilding process of the World Trade Center was affected by patriotism. He also assessed the dissent of civic ...
mAP (mean average precision) is the average of AP. In some context, we compute the AP for each class and average them. But in some context, they mean the same thing. For example, under the COCO context, there is no difference between AP and mAP. Here is the direct quote from COCO:...
