WebOct 30, 2024 · Figure: Tanh Derivative It is also known as the hyperbolic tangent activation function. Like sigmoid, tanh also takes a real-valued number but squashes it into a range between -1 and 1. Unlike sigmoid, tanh outputs are zero-centered since the scope is between -1 and 1. You can think of a tanh function as two sigmoids put together. WebHaving stronger gradients: since data is centered around 0, the derivatives are higher.
