A new research paper published on arXiv introduces a novel statistical method for parameter estimation. This method accelerates the estimation rate from the classical $n^{-1/2}$ to $n^{-1}$ by leveraging quality labels associated with each data sample. The approach is effective for both identifiable and finitely ambiguous quality classifiers, and it can retain the accelerated rate even when the quality model is known only up to an additive constant. The paper demonstrates that pointwise qualities and pairwise preferences are incomparable in their informativeness and provides a minimax lower bound to establish the optimal $n^{-1}$ dependence on sample size.
