counts of the X IJ entry and then we're going to do it is we're gonna look up the rector representation of word I and the vector representation of word J we're just gonna say their dot product should be proportional to the log occurrence count and that's all this is and so it's really simple and you can just use a weighted like square to error loss so that's what this this FX IJ is a basically a weighting function to account for the fact that some words are way more common and you don't want to over train this thing on like those
