What is hyperbolic tangent activation function?
The hyperbolic tangent activation function is also referred to simply as the Tanh (also “tanh” and “TanH“) function. It is very similar to the sigmoid activation function and even has the same S-shape. The function takes any real value as input and outputs values in the range -1 to 1.
Where is tanh activation function used?
The function is monotonic while its derivative is not monotonic. The tanh function is mainly used classification between two classes. Both tanh and logistic sigmoid activation functions are used in feed-forward nets.
What is the function of tangent?
The tangent function is one of the basic trigonometric functions. Tangent is defined as the ratio of the opposite side to the adjacent side of a specific angle of a right-angled triangle.
What are the representations of the hyperbolic tangent?
The hyperbolic tangent function has representations that use the trigonometric functions: The hyperbolic tangent function is used throughout mathematics, the exact sciences, and engineering.
Why are the hyperbolic functions cut off in calculus?
If your device is not in landscape mode many of the equations will run off the side of your device (should be able to scroll to see them) and some of the menu items will be cut off due to the narrow screen width. The last set of functions that we’re going to be looking in this chapter at are the hyperbolic functions.
Are there any hyperbolic functions similar to trig functions?
You’ll note that these are similar, but not quite the same, to some of the more common trig identities so be careful to not confuse the identities here with those of the standard trig functions.
Is it easy to find derivatives of hyperbolic functions?
Because the hyperbolic functions are defined in terms of exponential functions finding their derivatives is fairly simple provided you’ve already read through the next section. We haven’t however so we’ll need the following formula that can be easily proved after we’ve covered the next section.
