title: low Map with faster rcnn model
body: <p>I want to build Faster-RCNN model to detect human i followed this article <a href="https://towardsdatascience.com/faster-r-cnn-object-detection-implemented-by-keras-for-custom-data-from-googles-open-images-125f62b9141a" rel="nofollow noreferrer">https://towardsdatascience.com/faster-r-cnn-object-detection-implemented-by-keras-for-custom-data-from-googles-open-images-125f62b9141a</a>
  The problem that the mAP (mean average precision) doesn’t increase as the loss decreases. The max mAP i get is 0.355.
  Please i need your help to find a solution for this issue as soon as possible!
  or Can somebody please refer me good sources to build a strong model with faster rcnn to detect human using pascal voc dataset.</p>
