A Gentle Introduction to Learning Curves


(...) a learning curve is a plot that shows time or experience on the x-axis and learning or improvement on the y-axis.

The above learning curve, for example, shows a model that has been overfit: the model continues to better fit the training dataset while showing no improvements on validation. This comes through very clearly in the plot and demonstrates the power of learning curves as a tool for ML diagnosis.

Simple, powerful.
