English(EN) When Does Data Value Reduce to Class Balance? A Coverage View of Per-Point Data Valuation

新研究质疑每点数据估值法对AI训练的有效性

一篇新论文提出,当目标是识别最有价值的数据点时,诸如Data Shapley之类的每点数据估值分数并非理想选择。作者认为,一个数据点的价值是依赖于上下文的,如果它与已选数据几乎重复,其价值就会降低。他们建议,与固定的top-k评分相比,考虑已选数据的自适应覆盖率是一种更有效的策略,尤其是在数据选择至关重要且预算有限的情况下。 AI

影响 提出了选择训练数据的替代方法,可能通过避免冗余数据点来提高模型性能。

    数据价值何时会因类别平衡而降低?从覆盖率视角看每点数据估值

    arXiv:2610.34801v1 Announce Type: new Abstract: Per-point data-valuation scores -- Data Shapley, influence, leverage -- are routinely used to select training data: keep the points with the top $k$ scores. We argue that top-$k$ by a fixed, mode-blind per-point score is the wrong s…
