研究发现:机器学习中的良性过拟合未能预测股权回报

一篇新的arXiv论文探讨了“良性过拟合”在股权回报预测中的现象。研究表明,尽管高度过参数化的机器学习模型可以有效地插值训练数据,但与更简单的基准相比,它们在股权回报预测方面并未产生更高的预测能力。研究观察到无脊模型中存在双下降模式,并发现最优脊模型在高参数-观测比下仅比无脊模型有微不足道的改进。最终,这两种先进模型都未能跑赢基本的历史平均值,这表明即使在复杂的机器学习架构中,标准的股权预测器也缺乏真正的预测能力。 AI

影响 表明当前机器学习架构在金融预测方面的局限性,即使采用了良性过拟合等先进技术。

    对股票回报预测中良性过拟合的(误)理解

    arXiv:2608.23761v1 Announce Type: new Abstract: Highly overparameterized models often predict well despite interpolating training data in complex domains, challenging the classical bias--variance tradeoff. We investigate whether this ``benign overfitting'' phenomenon extends to e…
