    Google 与 HHMI Janelia 发布完整雄性果蝇脑连接组图谱

    Google Research 与 HHMI Janelia 等机构合作,在 Cell 发表论文,发布完整雄性果蝇大脑与中枢神经系统连接组图谱,包含超过 166,000 个神经元和 1.25 亿个突触连接,是迄今神经元数量最多的脑图谱。该图谱还涵盖相当于脊髓的腹神经索,并已由 HHMI Janelia 专家团队完成标注与校对,可通过开源工具 Neuroglancer 查看、探索和下载。它与已发布的雌性果蝇脑图谱互补,可用于比较两性神经元差异,研究求偶与攻击行为的生物学机制。

    Google Research 如何用 Diffusion Controller 统一并简化 AI 图像生成

    Google Research 提出 Diffusion Controller,一个轻量级“转向阻尼器”网络,可在主模型完全冻结的情况下动态调整图像生成轨迹,提升提示词对齐与画质。其完全解锁版本在实验中相对基线模型取得 90% 胜率,并可直接接入闭源模型。该框架把去噪过程重构为连续控制问题,并给出基于 PPO 策略梯度与奖励加权损失两种微调方法。
