- intuition - What is perplexity? - Cross Validated
So perplexity represents the number of sides of a fair die that when rolled, produces a sequence with the same entropy as your given probability distribution Number of States OK, so now that we have an intuitive definition of perplexity, let's take a quick look at how it is affected by the number of states in a model

Perplexity AI 不是搜索的终点，但可能是我们逃离“信息垃圾场”的起点。 它就像是搜索引擎界的 GPT-4：懂你说什么，还知道去哪儿找答案。 当然，要是它哪天推出 Pro 会员，也别忘了上拼团看看有没有便宜团能拼，不然 AI 会用，钱包也得会养哈哈~
- 求通俗解释NLP里的perplexity是什么？ - 知乎
困惑度 Perplexity 是衡量语言模型好坏的指标，为了更好地理解其意义，首先有必要回顾熵的概念。 根据信息论与编码的知识，我们知道 熵代表着根据信息的概率分布对其编码所需要的最短平均编码长度。

- clustering - Why does larger perplexity tend to produce clearer . . .
The larger the perplexity, the more non-local information will be retained in the dimensionality reduction result Yes, I believe that this is a correct intuition The way I think about perplexity parameter in t-SNE is that it sets the effective number of neighbours that each point is attracted to
