Encoder-aware Target Representation Construction: For T5 [50] encoders, we average the valid tokens excluding padding and end-of-text tokens, tiling the result to the maximum sequence length. For CLIP [51] encoders, explicit concepts use the last subject token, while implicit concepts use the aggregated mean from the last subject to the end-of-text token, with both similarly tiled to the fixed sequence length. b. Concept Erasure in Generation: Demonstrates the integration of our value-space intervention mechanism within the generative pipelines of diverse architectures, including U-Net- and DiT-based diffusion models and AR models. c. Uni-AdaVD: Details the core operations of our framework, which employs Orthogonal Value Decomposition (OVD) to erase target concepts in the value space and utilizes Layerwise Adaptive Erasing Shift (LAES) to adaptively modulate erasure strength for high-fidelity prior preservation.这张图概括 Uni-AdaVD 的整体方法流程。阅读时先看模块之间传递的训练信号,再看作者如何把目标拆成可优化的子问题。

Uni-AdaVD removes the targeted identity, while largely preserving the semantic and structural integrity of non-target concepts compared to baselines.这张图概括 Uni-AdaVD 的整体方法流程。阅读时先看模块之间传递的训练信号,再看作者如何把目标拆成可优化的子问题。

实验看点

实验部分建议重点看两类证据:一是作者是否把方法收益和更强数据、更长训练、更大模型区分开;二是跨模型、跨数据或跨任务迁移是否还能保留同样趋势。

局限与读法

这篇论文的结论需要结合任务设置、训练数据规模和消融实验一起看;不要只凭单个指标判断它对通用视觉表征的价值。
