It does this by regressing the offset between the location of the object's center and the center of an anchor box, and then uses the width and height of the anchor box to predict a relative scale of the object. The main things to remember here are that you can pass one sentence or a list of sentences, as well as specifying the type of tensors you want to get back (if no type is passed, you will get a list of lists as a result).
