论文摘要
我们回应了Courtoy等人提出的批评，其中质疑NNPDF4.0的忠诚，并暗示了NNPDF4.0 PDF不确定性的低估。我们列出，纠正并详细阐明了本参考中提出的许多不准确或误导性的主张。具体而言，我们解释并明确说明了为什么PDF分布的中心值通常与数据的绝对最小值不一致。我们检查了上述研究中构建的一些PDF，并声称是“良好的解决方案”：我们表明，使用NNPDF方法可以发现类似的PDF，但可能性很低。
We respond to the criticism raised by Courtoy et al., in which the faithfulness of the NNPDF4.0 sampling is questioned and an under-estimate of the NNPDF4.0 PDF uncertainties is implied. We list, correct, and clarify in detail a number of inaccurate or misleading claims that are made in this Reference. Specifically, we explain and explicitly demonstrate why the central value of the PDF distribution does not generally coincide with the absolute minimum of the $χ^{2}$ to the data. We examine some PDFs that have been constructed in the above study and claimed to be "good solutions": we show that similar PDFs are found with the NNPDF methodology, but with very low probability.
