Tanh function

The Tanh (hyperbolic tangent) function is a mathematical tool often used in machine learning to transform values into a range between -1 and 1. Think of it as a smooth switch that compresses large positive numbers toward 1, large negative numbers toward -1, and leaves small numbers relatively unchanged. This helps models understand patterns by normalizing data, making learning more efficient. Because of its symmetric nature around zero, Tanh is particularly useful when the data has balanced positive and negative features, helping neural networks process information more effectively.
