  2. Ramp function - Wikipedia

    en.wikipedia.org/wiki/Ramp_function

    The ramp function is a unary real function, whose graph is shaped like a ramp. It can be expressed by numerous definitions, for example "0 for negative inputs, output equals input for non-negative inputs". The term "ramp" can also be used for other functions obtained by scaling and shifting, and the function in this article is the unit ramp ...

  3. Rectifier (neural networks) - Wikipedia

    en.wikipedia.org/wiki/Rectifier_(neural_networks)

    Plot of the ReLU (blue) and GELU (green) functions near x = 0. In the context of artificial neural networks, the rectifier or ReLU (rectified linear unit) activation function [1] [2] is an activation function defined as the non-negative part of its argument, i.e., the ramp function:

  4. Macaulay brackets - Wikipedia

    en.wikipedia.org/wiki/Macaulay_brackets

    The above example simply states that the function takes the value () for all x values larger than a. With this, all the forces acting on a beam can be added, with their respective points of action being the value of a. A particular case is the unit step function,

  5. Universal approximation theorem - Wikipedia

    en.wikipedia.org/wiki/Universal_approximation...

    The above proof has not specified how one might use a ramp function to approximate arbitrary functions in (,). A sketch of the proof is that one can first construct flat bump functions, intersect them to obtain spherical bump functions that approximate the Dirac delta function , then use those to approximate arbitrary functions in C 0 ( R n , R ...

  6. Inclined plane - Wikipedia

    en.wikipedia.org/wiki/Inclined_plane

    Wheelchair ramp, Hotel Montescot, Chartres, France Demonstration inclined plane used in education, Museo Galileo, Florence.. An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load.

  7. Softplus - Wikipedia

    en.wikipedia.org/wiki/Softplus

    Plot of the softplus function and the ramp function.. In mathematics and machine learning, the softplus function is = ⁡ (+).It is a smooth approximation (in fact, an analytic function) to the ramp function, which is known as the rectifier or ReLU (rectified linear unit) in machine learning.

  8. Ramp (disambiguation) - Wikipedia

    en.wikipedia.org/wiki/Ramp_(disambiguation)

    Ramp function, in mathematics the integral of the unit step function; Receptor activity-modifying protein (RAMP), a class of protein (R)-1-amino-2-methoxymethylpyrrolidine, a chiral auxiliary used in the Enders SAMP/RAMP hydrazone-alkylation reaction
