MultiBox Los Calculation

[NiranjanRavi1993]

Hi,

In the multi-box loss calculation, in the parameter predicted_locs what does N signify? Is it the batch size or the number of objects predicted by the network in the particular image?

param predicted_locs: predicted locations/boxes w.r.t the 8732 prior boxes, a tensor of dimensions (N, 8732, 4)

Also I could see batch size derived here : batch_size = predicted_locs.size(0) . It would be helpful if any inputs on this.

Thanks and Regards
