Noisy Target vs Target Distribution,Deterministic Target vs Deterministic Target Func

Hello, I am confused by the meaning of these four words:

Noisy Target vs Target Distribution

I understand that a target distribution is a probability distribution, but how about noisy target? What is a noisy target? A value or a function or a probability distribution?

Deterministic Target vs Deterministic Target Function

Same above, I understand that a deterministic target function is a function, but how about deterministic target? A value or a function?

And...

Quote:
 Noisy target = deterministic target f(x) = E(y|x) plus noise y − f(x)
Is y here a value or a function?

I am very confused...

Thank you very much for your time spending on here.
