一项新的研究论文认为，测量噪声而不是模型限制是阻碍非线性模型在生物医学预测任务中表现的主要因素。该研究表明，加性噪声比线性结构更快地抹去非线性结构，从而削弱了复杂模型的优势。作者提出，提高测量可靠性，以及样本量和特征表示，对于灵活模型提供优势至关重要，而这在大多数生物医学应用中很少能满足。 AI
影响 强调了在特定AI应用中数据质量而非模型复杂性的关键作用，建议生物医学AI开发应转移关注点。

On biomedical tabular data, flexible models such as deep networks, gradient-boosted trees, and kernel methods are repeatedly matched or beaten by linear and logistic regression given the same features. The usual reaction is to treat this as a model-side shortfall, to be fixed wit…
