function is now going to cover the entire vocabulary and as long as you pick really negative samples you can be very efficient in terms of the kind of embeddings you learn and you don't really and and and so we won't really go into the details of that but you can refer to the paper in terms of what how hierarchical softmax is and negative sampling was used to make word to that really efficient and in terms of results the authors had really good results for the resulting word embeddings that we learned for instance here if you look at
