WebApr 6, 2024 · Here we can make two important observations. First, at low perplexity values 10 and even 30, the data structure is not obvious. Indeed, if I did not color the points it would be even hard to guess how many blobs we see in the tSNE plots for perplexity 10 and 30 as the data points seem to form somewhat dumbbell clusters. Therefore, in order to resolve … WebThe overall thesis that prediction=intelligence has been very strongly vindicated by, most notably recently in scaled-up language models trained solely with a self-supervised prediction loss who have near-perfect correlation of their perplexity/BPC compression performance with human-like text generation and benchmarks... but not a single SOTA of …

WebOct 8, 2024 · For example, the perplexity of a fair coin is two and the perplexity of a fair six-sided die is six. This provides a frame of reference for interpreting a perplexity value. That is, if the perplexity of some random variable X is 20, our uncertainty towards the outcome of X is equal to the uncertainty we would feel towards a 20-sided die.

WebPerplexity (PPL) is one of the most common metrics for evaluating language models. Before diving in, we should note that the metric applies specifically to classical language models (sometimes called autoregressive or causal language models) and is not well defined for masked language models like BERT (see summary of the models ).
