             <h1>原子核采样</h1>
 <p>这是原子核采样的一种实现，在论文<a href="https://papers.labml.ai/paper/1904.09751">《神经文本变性的好奇案例》</a>中进行了介绍。</p>
 <p>本文讨论了其他采样方法（例如光束搜索、<a href="temperature.html">纯采样、<a href="temperature.html">温度</a>采样</a>和T <a href="top_k.html">op-K采样</a>）存在的问题。本文介绍了原子核采样的概念，在文本生成方面，核采样的效果实际上比其他采样方法要好。</p>
