It is known that overfitting occurs when a conventional statistical learning method such as maximum likelihood estimation, maximum a posteriori estimation or Bayesian estimation is applied to hierarchical models. In this paper, we clarify the cause of why overfitting occurs when a conventional statistical learning method is applied to hierarchical models, and propose “Unbiased Learning” which is a learning framework based on unbiased likelihood (information criterion) for hierarchical models. We confirm the effectiveness of unbiased learning when applied to kernel regression model. |
