In the future blog post, I will talk about. valid or test) in the config. Those representations are compared and a distance between them is computed. But those losses can be also used in other setups. Then, a Pairwise Ranking Loss is used to train the network, such that the distance between representations produced by similar images is small, and the distance between representations of dis-similar images is big. Hence we have oi = f(xi) and oj = f(xj). Creates a criterion that measures the loss given Then, we aim to train a CNN to embed the images in that same space: The idea is to learn to embed an image and its associated caption in the same point in the multimodal embedding space. Note that oi (and oj) could be any real number, but as mentioned above, RankNet is only modelling the probabilities Pij which is in the range of [0,1].
