点击上方“Deephub Imba”,关注公众号,好文章不错过 !DiffusionGemma 的发布在 AI 研究圈子里引发了相当多的讨论，原因在于它触及了 LLM 文本生成方式的根本性问题。标准 Gemma 4 系列依赖自回归解码（autoregressive decoding），从前到后逐个预测 Token。DiffusionGemma 则是离散文本扩散（discrete text diff ...

These local LLMs are changing the game in lots of fun ways.

做光学设计的同行都懂，好镜头是“调”出来的，也是“等”出来的。Zemax里反复改曲率和厚度，Lumerical里扫描周期单元的相位响应，一个参数组合跑下来，工作站转一整天是常态。更别提无透镜成像的重建调参、叠层成像的扫描校正，每一步都靠手动调试和 ...

非侵入式路线通过头皮外的传感器采集大脑活动，无需动刀。安全性高、理论上可大规模部署。然而信号穿过颅骨和脑脊液后严重衰减，空间分辨率远逊于皮层内电极。但正是由于外置采集，解码能力就非常弱，目前仍然处于基本不可用的状态。
