C1W4 project assignment: how is the dictionary of english to french created?

I see one english word can be mapped to multiple french words. How is this dict created? Is there any practical application about it, or just created to build a class project? For document similarity, the transformation matrix makes sense. However, for word translation, I am confused why we need to do in this way: isn’t the dictionary itself the best translation?

Hi @larryleguo

Please re-watch video: Transforming word vectors and make sure you understand the main concepts. You have your answer at 2:50 in that video. Think about when you want to translate the sentence - is going word by word translation (dictionary lookup) is the best way to translate text?
