WebJun 23, 2016 · Then, note that: In fact, minimizing the arthemtic mean of the cross-entropy is identical to minimizing the geometric mean of the perplexity. If the model predictions are completely random, \mathbb {E} [\hat y_i^t]=\frac {1} {V} E[y^it] = V 1, and the expected cross-entropies are \log V log V, ( \log 10000\approx 9.21 log10000 ≈ 9.21)

The word likely is important, because unlike a simple metric like prediction accuracy, lower perplexity isn’t guaranteed to translate into better model performance, for at least two reasons. First, as we saw in the calculation section, a model’s worst-case perplexity is fixed by the language’s vocabulary size. charlie\u0027s hair shop

WebMay 26, 2024 · 1 Answer. Complexity classes and big-O notation are not the same thing. Big-O notation is just a notation to communicate the asymptotic behavior of a function; that is, O (f (n)) is the set of all functions that are upper bounded by c*f (n) for all n>N, where c and N are universal constants.
