Default Covariate Shift in Data

Dear Professor,

I have one question,
According to your slide.No.4 and page 14, "The Learning Diagram-with error".

Question. If we talk about covariate shift, in this the input probability distribution changes in training input and test input, but the functional relationship remains same. i.e [p(train(x)) Not equal to p(test(x))] but p(y,x) remains unchanged. In different words (covariate shifts is when only the distribution of covariates x change and everything remains same)

Then how should we modify you diagram in term of probability distribution, to show the covariate shift.
