We can see that a linear function (polynomial with degree 1) is not sufficient to fit the training samples. This is called underfitting. A polynomial of degree 4 approximates the true function almost perfectly.

WebThe splines period is the distance between the first and last knot, which we specify manually. Periodic splines can also be useful for naturally periodic features (such as day of the year), as the smoothness at the boundary knots prevents a jump in the transformed values (e.g. from Dec 31st to Jan 1st).
