新的迁移学习算法在潜在空间中建模以应对协变量偏移

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-14 04:00

研究人员引入了一种新颖的迁移学习算法，该算法通过结合样本重加权和表示学习来解决协变量偏移问题。该方法独特地在低维潜在空间中建模，而不是在高维环境空间中建模。该算法估计学习到的潜在特征的密度比，用于加权预测，并提供关于超额风险率的理论保证。在模拟数据和真实世界数据上的实验结果表明，将学习到的表示与潜在加权相结合可以带来性能提升。 AI

影响这项研究可以提高机器学习模型在数据分布变化场景下的鲁棒性。

协变量偏移下的潜在空间重要性加权

arXiv:2610.15571v1 Announce Type: new Abstract: In this work, we propose a transfer learning algorithm for covariate shift, integrating sample reweighting with representation learning. A key feature of our approach is the use of a lower-dimensional latent space for modeling, in c…
