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 ...
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,
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:

Receptor activity-modifying proteins (RAMPs) are a class of protein that interact with and modulate the activities of several Class B G protein-coupled receptors including the receptors for secretin, calcitonin (CT), glucagon, and vasoactive intestinal peptide (VIP). [1]
Airport ramp, the area where aircraft are loaded and unloaded; Linkspan, on a ferry or a ferry slip; Interchange (road) entrance ramp/on ramp or exit ramp/off ramp, on a freeway; Speed bumps, also called ramps; Wheelchair ramp, an alternative to stairs; Parking ramp, a multi-story structure for car parking with ramps between floors
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 ...
Smoothstep is a family of sigmoid-like interpolation and clamping functions commonly used in computer graphics, [1] [2] video game engines, [3] and machine learning. [ 4 ] The function depends on three parameters, the input x , the "left edge" and the "right edge", with the left edge being assumed smaller than the right edge.
