English(EN) Self-Generated Feedback Destabilizes Test-Time Training: A Causal Decomposition of Long-Horizon Adaptation

自我生成反馈破坏 AI 模型测试时训练

研究人员发现,测试时训练(TTT)中存在一个关键问题,即模型从自身生成输出来学习可能导致在独立数据上的性能下降。这种现象在包括 Qwen3-4B 在内的各种模型大小和配置中都有观察到,表明虽然写作本身不是失败原因,但基于自生成文本更新模型权重的过程可能导致重大的预测错误。该研究提出了解决方案,例如使用冻结模型进行生成,或使用“结算”机制在提交更新之前在独立文本上验证更新,这可以在保留适应能力的同时显著减少损害。 AI

影响 识别出测试时训练中的一个关键故障模式,可能影响持续适应模型的可靠性。

    自生成反馈破坏测试时训练:长时域适应的因果分解

    Test-time training (TTT) lets a model store information in its weights during inference. When the model learns from its own output, however, each update also changes the model that generates the next training example. Across 128K-token streams, retaining generated-text updates wo…
