Evaluate Topic Models: Latent Dirichlet Allocation (LDA)
WebFeb 22, 2024 · Like for example, you are having a four-sided dice with different probabilities for all different sides like 0.10, 0.40, 0.20 and 0.30. Now this dice is having the perplexity of 3.5961. In the same manner, if you have similar dice with all sides equal that can be 0.25, 0.25, 0.25 and 0.25 then its perplexity will be 4.0. Perplexity is sometimes used as a measure of how hard a prediction problem is. This is not always accurate. If you have two choices, one with probability 0.9, then your chances of a correct guess are 90 percent using the optimal strategy. The perplexity is 2 −0.9 log 2 0.9 - 0.1 log 2 0.1 = 1.38. The inverse of the … See more In information theory, perplexity is a measurement of how well a probability distribution or probability model predicts a sample. It may be used to compare probability models. A low perplexity indicates the … See more In natural language processing, a corpus is a set of sentences or texts, and a language model is a probability distribution over entire sentences or texts. Consequently, we can define the … See more The perplexity PP of a discrete probability distribution p is defined as $${\displaystyle {\mathit {PP}}(p):=2^{H(p)}=2^{-\sum _{x}p(x)\log _{2}p(x)}=\prod _{x}p(x)^{-p(x)}}$$ where H(p) is the entropy (in bits) of the distribution and x … See more • Statistical model validation See more chinchilla youth hub
