Using neural networks for localization of key fob within and surrounding a
car as a security feature for keyless entry is fast emerging. In this paper we
study: 1) the performance of pre-computed features of neural networks based UWB
(ultra wide band) localization classification forming the baseline of our
experiments. 2) Investigate the inherent robustness of various neural networks;
therefore, we include the study of robustness of the adversarial examples
without any adversarial training in this work. 3) Propose a multi-head
self-supervised neural network architecture which outperforms the baseline
neural networks without any adversarial training. The model's performance
improved by 67% at certain ranges of adversarial magnitude for fast gradient
sign method and 37% each for basic iterative method and projected gradient
descent method.
