ZQBA: Zero Query Black-box Adversarial Attack
Joana C. Costa, Tiago Roxo, Hugo Proença +1
Current black-box adversarial attacks either require multiple queries or diffusion models to produce adversarial samples that can impair the target model performance. However, thes…
LISArD: Learning Image Similarity to Defend Against Gray-box Adversarial Attacks
Joana C. Costa, Tiago Roxo, Hugo Proença +1
State-of-the-art defense mechanisms are typically evaluated in the context of white-box attacks, which is not realistic, as it assumes the attacker can access the gradients of the…
ASDnB: Merging Face with Body Cues For Robust Active Speaker Detection
Tiago Roxo, Joana C. Costa, Pedro Inácio +1
State-of-the-art Active Speaker Detection (ASD) approaches mainly use audio and facial features as input. However, the main hypothesis in this paper is that body dynamics is also h…
How to Squeeze An Explanation Out of Your Model
Tiago Roxo, Joana C. Costa, Pedro R. M. Inácio +1
Deep learning models are widely used nowadays for their reliability in performing various tasks. However, they do not typically provide the reasoning behind their decision, which i…
