激活函数虽然只是神经元里的一小步，但却是深度学习的一大步。没有它，深度学习就不会有今天的辉煌。它让神经网络从“线性堆叠”变成了真正的“非线性智能体”，能够处理复杂的视觉、语言和跨模态任务。
icon-to-image#As someone who primarily works in Python, what first caught my attention about Rust is the PyO3 crate: a crate that allows accessing Rust code through Python with all the speed and memory benefits that entails while the Python end-user is none-the-wiser. My first exposure to pyo3 was the fast tokenizers in Hugging Face tokenizers, but many popular Python libraries now also use this pattern for speed, including orjson, pydantic, and my favorite polars. If agentic LLMs could now write both performant Rust code and leverage the pyo3 bridge, that would be extremely useful for myself.，这一点在heLLoword翻译官方下载中也有详细论述
