Rekognition Custom Model Training with true negative images

When you mention negative labels, what should i exactly do here. I do not understand the last bullet point. Thanks for the help

Thanks for the response. I have gone through the link you shared. I still have doubt regarding this. I am using a bounding box for detecting an object. When you say the negative label then for such an image what bounding box shall i provide? This creates another scenario for me. If i provide the classification label instead of bounding box detection then do i also need to provide the true class classification label for training the custom model?
