Webbhave yielded many options for proving bounds on neural network outputs [Liu et al., 2024]. Given some region of the input space, these veriﬁcation tools deﬁne what values could be given by the neural network and provide either a guarantee of a correct output or a counterexample. Some tools work layer by layer through the network to compute WebbA counterexample is a specific example for which a statement is untrue. The existence counterexample proves the statement is false, even if it is often, mostly, or almost entirely true. Counterexamples are incredibly important for logic, which is, in turn, important because it provides the foundation for almost all mathematics. This section covers: bandara sangatta kalimantan timur
