本文如何被排名

Signal score: 0 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Commentary; 文章对一个核心 AI 概念（神经元）进行了基础性解释，没有发布新的研究或产品。
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: other; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: 79 days old; Aged out of breaking-news scoring windows; ranking reflects the durable signal from the full source set.

AI基础：什么是神经元？

<p>An artificial neural network is built by combining simple computational units called neurons. Each neuron takes in some numbers, performs a few calculations, and outputs a single number. That’s it.</p><p>So where does the intelligence come from? Not from any one neuron. It com…
