They have shown that when perturbing a single pixel in an image of size 32x32, they were able to significantly change the output of the neural network. To generate an attack, Nguyen et al. used an Evolutionary Strategy called Differential Evolution (DE). Evolutionary Strategies are algorithms that mimic biological genetic evolution. By using DE, they were able to conclude that it was a viable method in the generation of these attacks. In their research, they mentioned that future work could be devoted to looking at additional Evolutionary Strategies to increase the likelihood of successful attacks. Therefore, in this research, we extended Nguyen et al.’s work by using DE algorithms proposed from Qin and Suganthan called Adaptive Differential Evolution (AdaptiveDE) in one-pixel-attacks. Using this alternative algorithm we can generate more successful perturbations to increase the one-pixel-attack success rate.Item FIVE - Flexible Immersive Virtual Environments: A New Framework for Designing Environments for VR(2021) Schumacher, BrettFIVE is a development framework built for the Unity Game Engine to assist in the development of Virtual Environments intended for use in Virtual Reality. Our framework aims to allow developers to design environments that can change size to fit a user's physical spaces. This allows for more natural exploration of virtual spaces. The framework makes use of Unity's built in hierarchy and editor to streamline development. A variety of effects can be achieved using FIVE, such as static and relative translation/scaling, and object tiling. Despite limitations caused by angled objects, the framework provides a solid foundation for future work to explore a new system for developing Virtual Environments.
