Motivation Major Reference Zeroth order optimization, or derivative free optimization is also known as the oracle problem. It’s nothing new to optimization community. Interest in ZOO algorithm resurges partly because it could be used in black box adversarial attack, if the softmax probability is given; and it could also be used in optimization of experimental output; and it could also be used for many design problem as the result has a non-analytical relationship with the parameters.
Understanding of Adversarial Attack Why we should care adversarial examples? Why they are surprising? Adversarial example and feature visualization are related intrinsically. Basic algorithm underlying both is to generate image that activate a unit most. For Adversarial attack, the point is to change the image in an in-perceptible way but change the network output dramatically. On the other hand the feature visualization is to generate a perceptually meaningful pattern that represent a natural image that the unit like.
