However, there have been numerous reports that deep-learning classifiers are vulnerable to small input perturbations that have been carefully generated by adversaries. Vulnerabilities in deep learning can become potential threats to successful autonomous driving.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe objective of this research is to build robust deep-learning classifiers for various adversarial attacks in order to better protect self-driving cars. To address this challenge, Na and Ko propose embedding space for both classification and low-level (pixel-level) similarity learning that will ignore unknown pixel level perturbation.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThey also propose cascade adversarial training, which transfers the knowledge of the end results of adversarial training. This proposed approach shows improved accuracy compared to the current state-of-the-art adversarial training and ensemble adversarial training methodologies.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003EPhoto cutline:\u0026nbsp;\u003C\/strong\u003EECE Ph.D. students\u0026nbsp;Taesik Na and Jong Hwan Ko are pictured in the center of this photo.
