Abstract: 域偏移是人工智能模型从实验室走向真实场景的障碍。训练数据与实际数据常因设备、环境及采样条件不同而分布不一致,导致模型跨域性能下降。传统无监督领域自适应常通过调整深层特征缩小域差异,但需更新大量参数,计算开销高,且难以解释和控制。我们发现当预训练模型已形成稳定特征空间时,可将领域自适应转化为固定空间中的决策边界优化,并提出了Feature-Space Planes Searcher领域自适应框架:无需重塑特征,只需利用目标域已有的结构先验与几何模式,如类内紧凑、类间分离、边界避开高密度区域,搜索更符合目标分布的决策平面。实验表明,仅调整决策边界也能实现高效、稳定、可解释的跨域迁移。该框架适用于自然图像、蛋白质结构预测、遥感分类和地震检测等多种场景,并为大模型低成本可靠部署提供新路径。
