文本序列生成解码过程中有用到 greedy search、维特比算法、beam search等。 1. Beam Search 介绍 beam search尝试在广度优先基础上进行进行搜索空间的优化(类似于剪枝)达到减少内存消耗的目的。 算法过程 定义词表大小是V,beam size是 B,序列长度是L。 假设V=100,B=3: 1. 生成第1个词时,选择概率最大的3个...

设batch_size = 3, vocab_size = 6, beam_size(即num_beams) = 2,则我们需要首先复制bos(即sos) token为(batch_size * num_beams, 1),这里我们将行索引命名为beam id。解码器预测后并与之前保存的log_prob求和得到(batch_size * num_beams, vocab_size), 将其展开为(batch_size, num_beams * voca...

The minimum scattering angle is usually chosen in terms of Debye length or beam size. The lower limit is taken to be $$\begin{aligned} \theta _{min} \approx \frac{2r_e m^2c^2}{b_{max}p^2} = \frac{2r_e }{\sigma _x\bar{\beta }^2}, \end{aligned}$$ ...
