稍微的筆記

Pattern Recognition and Machine Learning ─ Bishop
  • Over-fitting: The fitted curve oscillates wildly and gives a very poor representation.
Methods of avoiding over-fitting:
    1. Increase the size of the data set (to increase the complexity or flexibility of the model)
    1. Maximum likelihood (by adopting Bayesian approach)
    1. 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。
