Learning Curves 可以分为三种：

• Underfit
• Overfit
• Good Fit

Underfit

A plot of learning curves shows underfitting if:

• The training loss remains flat regardless of training
• The training loss continues to decrease until the end of training

Overfit

A plot of learning curves shows overfitting if:

• The plot of training loss continues to decrease with experience
• The plot of validation loss decreases to a point and begins increasing again

Good Fit

A plot of learning curves shows a good fit if:

• The plot of training loss decreases to a point of stability
• The plot of validation loss decreases to a point of stability and has a small gap with the training loss
