Additional features can also cause overfitting if they have low or misleading information.
Consider the following problem:
X = [1, 3, 3, 4, 5], Y = [1, 3, 4, 4, 5].
Suppose that the real dataset was generated from the relationship:
Y = X, with a probability of 0.2 of adding or subtracting 1.
A reasonable model estimate is Y = X. Note that no model can ...
