A Lyapunov function for an autonomous dynamical system {: ˙ = ()with an equilibrium point at = is a scalar function: that is continuous, has continuous first derivatives, is strictly positive for , and for which the time derivative ˙ = is non positive (these conditions are required on some region containing the origin).
Plot of the Rosenbrock function of two variables. Here =, =, and the minimum value of zero is at (,).. In mathematical optimization, the Rosenbrock function is a non-convex function, introduced by Howard H. Rosenbrock in 1960, which is used as a performance test problem for optimization algorithms.

The Fédération Internationale de Football Association (lit. ' International Federation of Association Football '), more commonly known by its acronym FIFA (/ ˈ f iː f ə / FEE-fə), is the international self-regulatory governing body of association football, beach soccer, and futsal.
For β = 0, the function turns into the scaled linear function f(x) = x/2. [1] With β → ∞, the sigmoid component approaches a 0-1 function pointwise, so swish approaches the ReLU function pointwise. Thus, it can be viewed as a smoothing function which nonlinearly interpolates between a linear function and the ReLU function. [1]
Character.ai was established in November 2021. [8] The company's co-founders, Noam Shazeer and Daniel De Freitas, were both engineers from Google. [9] While at Google, the co-founders both worked on AI-related projects: Shazeer was a lead author on a paper that Business Insider reported in April 2023 "has been widely cited as key to today's chatbots", [10] and De Freitas was the lead designer ...
Lego Star Wars (stylized as LEGO Star Wars) is a Lego theme based on the Star Wars media franchise created by George Lucas.It includes over 928 Lego building toy sets, [1] 1389 Lego minifigures, [2] an eponymous video game series containing six games, and multiple animated short films and television series.
This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic hash functions. This list is incomplete ; you can help by adding missing items . ( February 2024 )
It used SHA-256, a cryptographic hash function, in its proof-of-work scheme. [21] [22] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS. In October 2011, Litecoin was released, which used scrypt as its hash function instead of SHA-256. Peercoin, created in August 2012, used a hybrid of proof-of-work and proof-of ...
