    FAITH: A feasibility-aware safety filtering reinforcement learning framework for high-dimensional systems

    Proposes the FAITH safe filtering reinforcement learning framework, training high-dimensional systems to optimize task reward under constraints

    Published
    AbstractFAITH separates safety filtering from reward optimization.

    FAITH is a model-free safe filtering reinforcement learning framework for high-dimensional systems: safety correction and task reward reside in separate modules.

    SIGMA:让模型依据 Model Spec 自我改进安全对齐

    提出 SIGMA,让模型依据 Model Spec 自造对齐数据并改进安全对齐

    Published
    Setting
    AI Agent
    Evaluated models
    Qwen3.6-27B
    AbstractSIGMA 用 Model Spec 自造监督,单轮训练可迁到多项智能体安全指标。

    SIGMA 让 Qwen3.6-27B 只凭 Model Spec 和高层领域,自己生产对齐任务、评分细则和奖励。

    CorrGRPO:面向多奖励学习的相关性归一化 GRPO

    提出 CorrGRPO,用 Pearson 相关归一化多奖励优势

    Published
    Setting
    AI Agent
    Evaluated models
    Qwen2.5-Coder-0.5B-Instruct, Qwen2.5-Coder-1.5B-Instruct, Qwen2.5-Coder-3B-Instruct and others8
    AbstractCorrGRPO 用 Pearson 相关归一化多奖励 GRPO 优势,并在三个域报告改进。

    CorrGRPO 是 GRPO 的多奖励变体:组内优势的分子仍是中心化总奖励,分母改为 Pearson 相关之和,避免大尺度奖励主导归一化。

    SafeEvolve:基于智能体经验的 Harness-Policy 协同演化安全对齐框架

    提出 SafeEvolve,用轨迹证据协同演化安全 harness 与策略

    Published
    Setting
    AI Agent
    Evaluated models
    Qwen3.5-4B, Qwen3-4B-Instruct-2507, Qwen3.5-1.7B and others4
    AbstractSafeEvolve 用轨迹证据协同更新安全 harness 和策略,在两个 4B 模型的智能体安全基准上改变安全与效用。

    SafeEvolve 把已完成的 on-policy 轨迹变成安全 harness 的有界更新,并用两阶段 SFT-RL 把这些更新内化进工具使用策略。
