  2. Generating function - Wikipedia

    en.wikipedia.org/wiki/Generating_function

    An example where convolutions of generating functions are useful allows us to solve for a specific closed-form function representing the ordinary generating function for the Catalan numbers, C n. In particular, this sequence has the combinatorial interpretation as being the number of ways to insert parentheses into the product x 0 · x 1 ·⋯ ...

  3. Central pattern generator - Wikipedia

    en.wikipedia.org/wiki/Central_pattern_generator

    Central pattern generators can also play a role in rhythm generation for other functions in vertebrates. For example, the rat vibrissa system uses an unconventional CPG for whisking movements. "Like other CPGs, the whisking generator can operate without cortical input or sensory feedback.

  4. Presentation of a group - Wikipedia

    en.wikipedia.org/wiki/Presentation_of_a_group

    Informally, G has the above presentation if it is the "freest group" generated by S subject only to the relations R. Formally, the group G is said to have the above presentation if it is isomorphic to the quotient of a free group on S by the normal subgroup generated by the relations R. As a simple example, the cyclic group of order n has the ...

  5. Artificial intelligence - Wikipedia

    en.wikipedia.org/wiki/Artificial_intelligence

    [b] AI also draws upon psychology, linguistics, philosophy, neuroscience, and other fields. [5] Artificial intelligence was founded as an academic discipline in 1956, [6] and the field went through multiple cycles of optimism throughout its history, [7] [8] followed by periods of disappointment and loss of funding, known as AI winters.

  6. Generative model - Wikipedia

    en.wikipedia.org/wiki/Generative_model

    For example, GPT-3, and its precursor GPT-2, [11] are auto-regressive neural language models that contain billions of parameters, BigGAN [12] and VQ-VAE [13] which are used for image generation that can have hundreds of millions of parameters, and Jukebox is a very large generative model for musical audio that contains billions of parameters. [14]

  7. Generation effect - Wikipedia

    en.wikipedia.org/wiki/Generation_effect

    The generation effect is typically achieved in cognitive psychology experiments by asking participants to generate words from word fragments. [2] This effect has also been demonstrated using a variety of other materials, such as when generating a word after being presented with its antonym, [3] synonym, [1] picture, [4] arithmetic problems, [2] [5] or keyword in a paragraph. [6]

  8. Cumulant - Wikipedia

    en.wikipedia.org/wiki/Cumulant

    For a degenerate point mass at c, the cumulant generating function is the straight line () =, and more generally, + = + if and only if X and Y are independent and their cumulant generating functions exist; (subindependence and the existence of second moments sufficing to imply independence.

  9. Probability-generating function - Wikipedia

    en.wikipedia.org/.../Probability-generating_function

    Other generating functions of random variables include the moment-generating function, the characteristic function and the cumulant generating function. The probability generating function is also equivalent to the factorial moment generating function , which as E ⁡ [ z X ] {\displaystyle \operatorname {E} \left[z^{X}\right]} can also be ...
