Nonlinear Transformations

Nonlinear transformations are mathematical processes that change data in a way that isn’t straight-line or proportional. Unlike simple adjustments where doubling a value doubles the result, nonlinear transformations can make small inputs result in larger or different outputs, or vice versa. They’re used to highlight patterns, reduce skewed data, or make complex relationships more understandable. Think of it like zooming in or out in a photo—distorting or reshaping it to better see details or fit a certain view, while preserving the inherent relationships within the data.
