本文深入探讨Transformer模型中三种关键的注意力机制：自注意力、交叉注意力和因果自注意力。这些机制是GPT-4、Llama等大型语言模型（LLMs）的核心组件。通过理解这些注意力机制，我们可以更好地把握这些模型的工作原理和应用潜力。 我们不仅会讨论理论概念，还将使用Python和PyTorch从零开始实现这些注意力机制。通过实际编码，我们可以更深入地理解这些机制的内部工作原理。 通过这种结 ...

Llamas and alpacas can be a wonderful addition to a family farm and make great pets. The 4-H llama and alpaca project helps you find the kind of llama or alpaca that fits into your family’s lifestyle.

Who wouldn’t want to a be llama? You'd quite possibly get to live in South America, graze in the sun, spend time with your ...

今天凌晨，大新闻不断。一边是 OpenAI 的高层又又又动荡了，另一边被誉为「真・Open AI」的 Meta 对 Llama 模型来了一波大更新：不仅推出了支持图像 ...

10亿参数和30亿参数的轻量级纯文本模型 官方数据显示，与同等规模的“中小型”大模型相比，Llama 3.2 11B和90B表现出了超越闭源模型的性能。

This small gold model of a llama is a fitting offering for an Inca mountain god. The Incas revered gold as the sweat of the sun and believed that it represented the sun's regenerative powers.

近期有研究表明，如果将系统 2 过程整合进 Transformer 和大型语言模型中，就能显著提升它们的推理能力。尽管如此，如果模型只是模仿系统 2 式的思考过程，那就需要远远更高的计算成本才能完成，同时响应速度也会大幅减慢。
