Can you explain what the tanh function is?
The tanh function, or hyperbolic tangent, is a mathematical function that maps real numbers to the range (-1, 1). It is defined as the ratio of the hyperbolic sine to the hyperbolic cosine.
What are its properties?
The tanh function is odd, continuous, and differentiable. It has a range of (-1, 1) and approaches these values asymptotically as x approaches positive or negative infinity.
How is it used in machine learning?
In machine learning, the tanh function is often used as an activation function in neural networks because it helps to normalize the output and can lead to faster convergence.
Can you give me a graph of the tanh function?
Sure! The graph of the tanh function is an S-shaped curve that crosses the origin, with horizontal asymptotes at y = 1 and y = -1.
