Introuduction to ML strategy

 

⭐ 현재 상황을 파악하고, 그에 맞게 대처하는 것이 중요하다.

 

• 1. fit training set well on cost function
  • bigger network
  • Adam optimizer 사용
  • more epoch
• 2. fit dev set well on cost function
  • regularization
  • more training data
• 3. fit test set well on cost function
  • bigger dev set
• 4. perform well in real word
  • change dev set
  • change cost function
