A Neural Sheet Discovers the Shape of Data

A self-organizing map (SOM) starts as a flat sheet of neurons with no knowledge of the data around it. For every input sample, it finds the best-matching neuron,

c = argminᵢ ‖x - wᵢ‖,

and updates that neuron together with its neighbours,

wᵢ ← wᵢ + η(t)hᶜᵢ(t)(x - wᵢ).

As the neighbourhood radius shrinks during training, the sheet gradually bends and folds onto the hidden geometry of the dataset while preserving its neighbourhood structure.

Developed by Finnish computer scientist Teuvo Kohonen, the Self-Organizing Map remains one of the most elegant examples of competitive learning, where order emerges from thousands of simple local updates.

Tensors generalize vectors as lists and matrices as grids into higher-order arrays like 3D cubes.

Comparisons include a vector as a list, a matrix as a grid, and a 3-tensor as a cube, along with the stress tensor σij on a cube featuring arrows for components like σ11 and σ23, the product derivative rule, the Riemann curvature tensor R(u,v)w = ∇u ∇_v w − ∇_v ∇_u w − ∇[u,v]w, quantum superposition 1/√2(|00⟩ + |11⟩), and algebraic operations like the tensor product.

It is used to analyze internal forces and deformations in engineering materials and to describe the geometry of spacetime under gravity in general relativity.

Claude 做股票研究，是真的离谱。

它能帮你拆投资组合、揪出风险、
30 秒给你一份完整的交易计划。免费。

而财务顾问每小时收 700 美元。

收藏下面 7 个 prompt：

The Helmholtz decomposition is one of the fundamental results of vector calculus.

It says any well-behaved vector field can be split into two parts, one capturing sources and sinks through divergence, and one capturing rotation through curl.

分享10个我目前在用的 Skill

1. NotebookLM Skill

神级 Skill，通过它可以直接让 AI 对接 NotebookLM，自动上传资料、做知识问答、生成 PPT、脑图都能搞定。

2. Obsidian Skills

Obsidian CEO 出的 Skill 套件，功能很全：

写出 Obsidian 风格的 Markdown（内链、属性等）
生成 .Base 文件的过滤器和公式
生成 Canvas 无限画布

3. planning-with-files

复刻Manus 的Skil，可以用这个 Skill 来指导���他 Skill 的工作流程。能有效解决上下文飘移的问题。

4. anthropics/skill-creator

自己做 Skill 时候的首选，可以直接通过它创建一个符合最佳实践的 Skill，也可以用它来优化现有的 Skill。

5. frontend-design

前端设计专用，比如可以帮你去掉AI 的渐变色。。

6. Superpowers

Obra 开发的工具包,包含 /brainstorm、/write-plan、/execute-plan 等命令。

可以在你做复杂项目时，讨论方案、和你一起脑暴，还会通过提问来分析问题生成靠谱的方案

7. Rube MCP Connector

通过一个服务器就能把 Claude 连接到大概 500 个应用（Slack、GitHub、Notion 等），不用给每个应用单独配置授权。

8. baoyu-skills
