well so you know just I guess I guess it's a thing you could choose I don't know what exactly is the best thing alright then I forward the query through the FQ and I forward the keys through the FK then important I detach this so I don't train I don't want to train the FK I only want to train the FQ right then I do the bilinear product here with the W these these are the bilinear product and then I put this all of this into a cross entropy loss right in the end I update my fq m IW and i do this exponentially
