I read the paper Dissecting Recall of Factual Associations in Auto-Regressive Language Models by Geva et al., and I highly recommend it. If you’re curious about how large language models process in...

In the last post of this series, we tried the instruction-tuned IT model. In this post, we focus on the raw PT model. The following is Table 15 from the Gemma 3 technical report. It compares the p...

In the first post of this series, we examined the specifications of the Gemma 3 model. In this post, we will actually run it and get an intuitive understanding of the inference process. I will assu...

Recently, I’ve become quite fascinated by small LLMs such as Gemma 3 and the idea of running them locally. I tried out Ollama, which builds on top of llama.cpp but wraps it in an elegant, user-frie...

I have attempted to learn the Transformer multiple times. When the now-classical paper Attention Is All You Need first came out in 2017, I was attracted by its title. That was about 5 years after ...

时空一渺， 转瞬即逝， 光影留真， 方得长存。

既然选了 M43，应该是冲着便携，GX7 比 GX8、GX85 和 GX9 都更小更轻。 一个电池 GX7 能拍 330 张，GX8 拍 300 张，GX85 拍 290 张，GX9 只能拍 260 张。 GX7 性价比更高，2000 一个套机。 镁合金机身，结实，磕碰不心疼。GX85 好像是塑料的。另外电子快门 GX7 是 12bit，GX85 阉割到 10bit。C 模式从三...

微单这步棋走对了吗？ 昨天搞了个 10 年前发布的松下 GX7，把玩了一会，什么都很赞，就是这个电子取景器我真不理解。只用过单反，这是第一次用电子取景器。调了半天屈光度，怎么都没法完全调清楚。我的单反没这个问题，贼清楚。 清晰度暂且不说，微单和单反的光学取景器体验真的是没法比。发着光的数字显示器，完全没有了光学的自然即时感，晚上还亮眼，贴这么近没人担心蓝光伤眼吗？单反上的光学取景和 LC...

学习摄影，顺便也学学摄像。看到我的松下 GX7 视频模式里有快门优先，非常疑惑：难道快门速度不应该正好是帧率的倒数吗？ 于是研究了一番，才知道原来还有 180 度快门这个说法，也学到了特殊快门的作用。太有趣了！

问了下 GPT。顺便感叹下，大模型时代学摄影真爽啊！ 根据需求决定固定快门速度还是光圈 场景 固定快门速度 固定光圈 电影感画面（自然的运动模糊） 是（1/50s、1/60s 等） 可调整 浅景深（背景虚化） 可调整 ...
