On the Real-World Adversarial Robustness of Real-Time Semantic Segmentation Models for Autonomous Driving.

The existence of real-world adversarial examples (RWAEs) (commonly in the form of patches) poses a serious threat for the use of deep learning models in safety-critical computer vision tasks such as visual perception in autonomous driving. This article presents an extensive evaluation of the robustness of semantic segmentation (SS) models when attacked with different types of adversarial patches, including digital, simulated, and physical ones. A novel loss function is proposed to improve the capabilities of attackers in inducing a misclassification of pixels.

Detecting Adversarial Examples by Input Transformations, Defense Perturbations, and Voting.

Over the past few years, convolutional neural networks (CNNs) have proved to reach superhuman performance in visual recognition tasks. However, CNNs can easily be fooled by adversarial examples (AEs), i.e.

Axion-Mediated Forces, CP Violation, and Left-Right Interactions.

We compute the CP-violating scalar axion coupling to nucleons in the framework of baryon chiral perturbation theory and we apply the results to the case of left-right symmetry. The correlated constraints with other CP-violating observables show that the predicted axion nucleon coupling is within the reach of present axion-mediated force experiments for M_{W_{R}} up to 1000 TeV.

Lepton Number Violation in Higgs Decay at LHC.

We show that within the left-right symmetric model, lepton number violating decays of the Higgs boson can be discovered at the LHC. The process is due to the mixing of the Higgs boson with the triplet that breaks parity. As a result, the Higgs boson can act as a gateway to the origin of the heavy Majorana neutrino mass.

Three extra mirror or sequential families: case for a heavy Higgs boson and inert doublet.

We study the possibility of the existence of extra fermion families and an extra Higgs doublet. We find that requiring the extra Higgs doublet to be inert leaves space for three extra families, allowing for mirror fermion families and a dark matter candidate at the same time. The emerging scenario is very predictive: It consists of a standard model Higgs boson, with a mass above 400 GeV, heavy new quarks between 340 and 500 GeV, light extra neutral leptons, and an inert scalar with a mass below M(Z).
