Spline Fitting

Spline fitting is a mathematical technique used to create a smooth curve that closely follows a set of data points. Imagine connecting dots with a flexible, smooth ribbon rather than straight lines; splines are those ribbons. They are made up of multiple small, curved segments joined smoothly at specific points, called knots. This method helps in modeling complex shapes or trends within data, providing an accurate and continuous representation without overfitting. Spline fitting is widely used in computer graphics, data analysis, and engineering for creating smooth, reliable curves that reflect the underlying pattern of data.
