Perplexity is sometimes used as a measure of the difficulty of a prediction problem. It is, however, generally not a straight forward representation of the relevant probability. For example, if you have two choices, one with probability 0.9, your chances of a correct guess using the optimal strategy are 90 percent.
Perplexity measures how well a model predicts the contents of a dataset; the higher the likelihood the model assigns to the dataset, the lower the perplexity. In mathematical terms, perplexity is the exponential of the average negative log likelihood per token.
This also applies to Perplexity AI and other AI "conversational" search engines like Microsoft Bing with ChatGPT integration, YouChat and other models that claimed to answer to complex questions but for a different reason; they cite unreliable sources (some if not most of which are listed in perennial sources list), Wikipedia itself, and/or ...
Readability is the ease with which a reader can understand a written text.The concept exists in both natural language and programming languages though in different forms. In natural language, the readability of text depends on its content (the complexity of its vocabulary and syntax) and its presentation (such as typographic aspects that affect legibility, like font size, line height ...
Given the long list of companies that have tried and failed, challenging Google seems to be a losing proposition. Yet Amazon founder Jeff Bezos recently placed a bet on Perplexity AI, a startup ...
