A family $\mathcal{C}$ of circuits/functions is "learnable with oracle queries" if there is an efficient "learning" algorithm $L$ that, given oracle (or "black box") access to any $C \in \mathcal{C}$, outputs a circuit $C'$ (or other representation) that is equivalent to $C$, i.e., it agrees with $C$ on all inputs. Oracle ("black box") access to $C$ means ...
