新的训练目标 $\sigma$NB 在临床决策模型上表现不一

研究人员探索了一种名为平滑净收益($\sigma$NB)的新训练目标,作为机器学习模型传统方法(如伯努利负对数似然(NLL))的替代方案,特别是在临床决策制定背景下。他们使用 Framingham 等数据集和 TabZilla 基准测试,并结合逻辑回归、GAM 和 XGBoost 等模型进行了实验,结果喜忧参半。虽然 $\sigma$NB 在 TabZilla 数据集上的逻辑回归模型中提供了净收益的适度改进,但它并未持续优于 NLL,甚至在 GAM 模型上表现有所下降。研究表明,与作为 NLL 的通用替代方案相比,以决策为中心的优化在模型灵活性有限时可能最有益。 AI

影响 探索了可能提高 AI 模型在医疗保健等专业领域决策能力的替代训练目标。

    优化决策而非预测:对平滑净收益作为训练目标的探索

    arXiv:2609.12752v1 Announce Type: new Abstract: Objective Prediction models are commonly trained using objectives such as Bernoulli negative log-likelihood (NLL), although downstream clinical decisions may depend on specific risk thresholds. We introduce Smooth Net Benefit ($\sig…
