ChaCha (search engine) ChaCha was an American human-guided search engine that provided free, real-time answers to any question, through its website, or by using one of the company's mobile apps. The company, founded in 2006 by Scott A. Jones and Brad Bostic, was based in Carmel, Indiana, United States, part of the Indianapolis metropolitan area.
Question answering. Question answering (QA) is a computer science discipline within the fields of information retrieval and natural language processing (NLP) that is concerned with building systems that automatically answer questions that are posed by humans in a natural language. [1]
In the field of artificial intelligence (AI), a hallucination or artificial hallucination (also called bullshitting, [1][2] confabulation[3] or delusion[4]) is a response generated by AI that contains false or misleading information presented as fact. [5][6][7] This term draws a loose analogy with human psychology, where hallucination typically ...
Using a = 4 and c = 1 (bottom row) gives a cycle length of 9 with any seed in [0, 8]. A linear congruential generator (LCG) is an algorithm that yields a sequence of pseudo-randomized numbers calculated with a discontinuous piecewise linear equation. The method represents one of the oldest and best-known pseudorandom number generator algorithms.
Lexical tokenization is related to the type of tokenization used in large language models (LLMs) but with two differences. First, lexical tokenization is usually based on a lexical grammar, whereas LLM tokenizers are usually probability -based. Second, LLM tokenizers perform a second step that converts the tokens into numerical values.
Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but impossible to foresee.
To do so technically would require a more sophisticated grammar, like a Chomsky Type 1 grammar, also termed a context-sensitive grammar. However, parser generators for context-free grammars often support the ability for user-written code to introduce limited amounts of context-sensitivity. (For example, upon encountering a variable declaration ...
Wordle is a web-based word game created and developed by Welsh software engineer Josh Wardle. Players have six attempts to guess a five-letter word, with feedback given for each guess in the form of coloured tiles indicating when letters match or occupy the correct position. Wordle has a single daily solution, with all players attempting to ...
