提出一种基于轨迹的数据集蒸馏框架,通过选择性指导重加权和教师启发辅助目标,在噪声监督下联合抑制噪声并保留可迁移知识,无需重标注或干净子集。

摘要:

数据集蒸馏(DD)将大型语料库压缩为紧凑、信息丰富的子集,用于高效训练和复用。然而,在噪声监督下,DD 有将损坏关联与有用信号一起压缩的风险,从而降低鲁棒性。传统的噪声标签修复方法(样本选择、损失加权、标签校正)将噪声估计与模型优化紧密耦合,通常需要干净锚点,并可能放大确认偏差——这些假设与 DD 的紧凑、即插即用监督目标不一致。因此,我们提出一种基于轨迹的 DD 框架,该框架在不重新标记或使用干净子集的情况下,联合抑制噪声并保留可迁移知识。它包含两个互补组件:选择性指导重加权(SGR),它将全局遗忘模式(二次分裂遗忘)与局部邻域一致性融合到渐进式重加权方案中,沿着教师轨迹优先考虑干净监督;以及教师启发辅助目标(TIAT),它注入从中间教师动态中提取的辅助残差指导,以增强信息信号,同时保持内部一致性。SGR 和 TIAT 共同在噪声监督下生成具有更干净和更丰富表示的蒸馏数据集。该框架鲁棒、标签保持、计算轻量且广泛适用,在对称、非对称和真实世界噪声下,相较于最先进的 DD 基线,均取得一致提升。

英文摘要:

Dataset distillation (DD) condenses large corpora into compact, information-rich subsets for efficient training and reuse. However, under noisy supervision, DD risks condensing corrupted associations together with useful signals, degrading robustness. Conventional noisy-label remedies (sample selection, loss weighting, label correction) tightly couple noise estimation with model optimization, often require clean anchors, and can amplify confirmation bias-assumptions that are misaligned with DD's goal of compact, plug-and-play supervision. We therefore propose a trajectory-based DD framework that jointly suppresses noise and preserves transferable knowledge without relabeling or clean subsets. It comprises two complementary components: Selective Guidance Reweighting (SGR), which fuses global forgetting patterns (second-split forgetting) with local neighborhood consistency into a progressive reweighting scheme that prioritizes clean supervision along the teacher trajectory; and Teacher-Inspired Auxiliary Targets (TIAT), which inject auxiliary residual guidance distilled from intermediate teacher dynamics to reinforce informative signals while remaining internally consistent. Together, SGR and TIAT produce distilled datasets with cleaner and richer representations under noisy supervision. The framework is robust, label-preserving, computationally lightweight, and broadly applicable, yielding consistent gains over state-of-the-art DD baselines across symmetric, asymmetric, and real-world noise.
