8-core processor is fairly understandable, though I might be biased. Knowing what the hell RMSE is requires some background in math, plus we use our own homebrew method of calculating RMSE, which you won’t find in literature. We can show log loss instead, but that also requires some background in math. Also, about the whole “20-30% fewer reviews” thing - it’s a lie. Well, not a lie, but it’s based on simulations. We haven’t measured it directly because it would be mighty difficult.
