sign function
11Sign of the Takahe — The Sign of the Takahe is today a function centre and tea rooms built in the style of an English Manor House. Designed by J.G. Collins, construction was carried out between 1918 and 1948. The Takahe also provides one of the better panoramic views …

13Logistic function — A logistic function or logistic curve is the most common sigmoid curve. It modelsthe S curve of growth of some set P . The initial stage of growth is approximately exponential; then, as saturation begins, the growth slows, and at maturity, growth …
14Heaviside step function — The Heaviside step function, H , also called the unit step function, is a discontinuous function whose value is zero for negative argument and one for positive argument.It seldom matters what value is used for H (0), since H is mostly used as a… …
15Error function — Plot of the error function In mathematics, the error function (also called the Gauss error function) is a special function (non elementary) of sigmoid shape which occurs in probability, statistics and partial differential equations. It is defined …
16Multiplication sign — The multiplication sign The multiplication sign is the symbol ×. The symbol is similar to the lowercase letter x but is a more symmetric saltire, and has different uses. It is also known as St. Andrew s Cross[1] and as the dimension sign. In …
17Numerical sign problem — The numerical sign problem refers to the difficulty of numerically evaluating the integral of a highly oscillatory function of a large number of variables. Numerical methods fail because of the near cancellation of the positive and negative… …
