UnverifiedThis research models the log density ratio between the target distribution and the base distribution as the negative of the base distribution's Stein operator applied to the displacement field, plus a normalization constant.74% similarUnverifiedIn nonparametric density estimation, the number of samples required to achieve ε accuracy grows at a rate of ε^(-D) with the ambient dimension D.71% similarUnverifiedAssuming the data follows a Gaussian distribution, maximizing the likelihood is equivalent to minimizing the mean squared error.65% similarUnverifiedA carefully curated and deduplicated high-quality dataset can train a model of equal or even superior capability using far fewer tokens than the original scale.64% similar
