The base of the logarithm need not be 2: The perplexity is independent of the base, provided that the entropy and the exponentiation use the same base. In some contexts, this measure is also referred to as the (order-1 true) diversity. Perplexity of a random variable X may be defined as the perplexity of the distribution over its possible ...
Perplexity AI is a conversational search engine that uses large language models (LLMs) to answer queries using sources from the web and cites links within the text response. [ 3 ] [ 4 ] Its developer, Perplexity AI, Inc., is based in San Francisco, California .
Perplexity is a measurement of how well a probability distribution or probability model predicts a sample. Perplexity may also refer to: Perplexity, a 1990 video game; Perplex City, an alternate reality game (ARG) Perplexity AI, a conversational search engine

The perplexity is a hand-chosen parameter of t-SNE, and as the authors state, "perplexity can be interpreted as a smooth measure of the effective number of neighbors. The performance of SNE is fairly robust to changes in the perplexity, and typical values are between 5 and 50.". [2]
PP also includes BQP, the class of decision problems solvable by efficient polynomial time quantum computers. In fact, BQP is low for PP, meaning that a PP machine achieves no benefit from being able to solve BQP problems instantly. The class of polynomial time on quantum computers with postselection, PostBQP, is equal to PP [5] (see #PostBQP ...
Acorn Electron screenshot. The top of the screen is using the display to store game data to fit the game into the Electron's limited memory. Perplexity is an isometric pseudo 3D maze game which graphically resembles the 1987 arcade game Pac-Mania (both the maze view and main characters) but while it does share some gameplay elements, the game is a much more calm and organised playing ...
