How to Use
Generate random data from a sine curve with noise. The three panels show underfitting (degree 1), a good fit (degree 4), and overfitting (degree 15). Use the sliders below to pick your own polynomial degree and regularization strength. Watch how the error curves change.
Underfitting (Degree 1)
High bias, low variance
Good Fit (Degree 4)
Balanced bias-variance
Overfitting (Degree 15)
Low bias, high variance
Your Fit (Degree 4, λ=0.00)
