sample pairs from negative sampling distribution. Finally, we calculate the mean square error according to the theorem we proved: A random variable √T(θT−θ∗)T(θT−θ∗) gradually converges to a distribution that contains a zero-meaned vector and covariance matrix: E[|(|θ_T-θ^* |)|² ]=1/T (1/(p_d (u│v)
