Pattern Recognition and Machine Learning ─ Bishop
- Over-fitting: The fitted curve oscillates wildly and gives a very poor representation.
Methods of avoiding over-fitting:
- Increase the size of the data set (to increase the complexity or flexibility of the model)
- Maximum likelihood (by adopting Bayesian approach)
- Regulization: Adding penalty to an error function.
\(E(\omega)=\dfrac{1}{2}\sum_{n=1}^{N}(y(X_n,\omega)-t_n)^2+\dfrac{\lambda}{2}||\omega||^2\), where \(\lambda\) denotes the regulization term.
今日其他進度:
- 日文N1文法、N1題目
- 一堆的動畫
我會繼續努力的。
