We give examples of this approach beyond linear regression to a general class that includes logistic regression and learning binary functions, and show that the corresponding budgeted mechanism design problem is also expressed through a submodular optimization. Hence, prior work \cite{chen,singer-mechanisms} immediately applies, and gives randomized, universally truthful, polynomial time, constant factor approximation mechanisms for problems in this class. Getting deterministic, truthful, polynomial time mechanisms with a constant approximation factor for this class or specific problems in it, like we did for \EDP, remains an open problem. -In what follows, we describe related work in Section~\ref{sec:related}. We briefly review experimental design and budget feasible mechanisms in Section~\ref{sec:peel} and define \SEDP\ formally. In Section~\ref{sec:main} we present our mechanism for \SEDP\ and state our main results, which are proved in Section~\ref{sec:proofs}. A generalization of our framework to machine learning tasks beyond linear regression is presented in Section~\ref{sec:ext}. +In what follows, we describe related work in Section~\ref{sec:related}.
