Web23 dec. 2024 · Hugging Face Forums Is beam search always better than greedy search? Beginners robz December 23, 2024, 7:49pm #1 How to generate text states: Beam search will always find an output sequence with higher probability than greedy search It’s not clear to me why that is the case. Web好了，我们已经完成了用GPT2生成短文本:blush:。生成的词接在原文后面还算合理，但是它总是在重复自己。这在当前的语言生成模型中很常见，尤其是greedy search和beam search，详见Vijayakumar et al., 2016和Shao et al., 2024。. greedy search的主要缺点是，它只考虑了当前的高概率词，忽略了在当前低概率词后面的 ...

Beam search will always find an output sequence with higher probability than greedy search, but is not guaranteed to find the most likely output. Let's see how beam search can be used in transformers.
