Texture- and Shape-based Adversarial Attacks for Vehicle Detection in Synthetic Overhead Imagery

Autor: Yeghiazaryan, Mikael, Namburu, Sai Abhishek Siddhartha, Kim, Emily, Panev, Stanislav, de Melo, Celso, Lance, Brent, De la Torre, Fernando, Hodgins, Jessica K.

Detecting vehicles in aerial images can be very challenging due to complex backgrounds, small resolution, shadows, and occlusions. Despite the effectiveness of SOTA detectors such as YOLO, they remain vulnerable to adversarial attacks (AAs), compromi

Cluster cosmology can benefit from combining multi-wavelength studies, which can benefit from characterising the correlation coefficients between different mass-observable relations. In this work, we aim to provide information on the scatter, the ske

Metastability in Coexisting Competing Orders

Autor: Sefidkhani, Yasamin Masoumi, de la Torre, Alberto, Fiete, Gregory A.

The dynamical phase transition of a system with two coexisting competing order parameters is studied using the time-dependent-Ginzburg-Landau framework. The dynamics are induced by parameters capturing the physics of driving the system with an ultraf

The aim of this study is to implement a method to remove ambient noise in biomedical sounds captured in auscultation. We propose an incremental approach based on multichannel non-negative matrix partial co-factorization (NMPCF) for ambient denoising

Quantification of Non-stationary Power Quality Events: A New Index Based on $\ell_p$-norm of Energy

Autor: Hafiz, Faizal, Naik, Chirag, La Torre, Davide, Swain, Akshya

The present study proposes a new index to quantify the severity of non-stationary power quality (PQ) disturbance events. In particular, the severity of PQ events is estimated from their energy distribution in temporal-frequency space. The index essen
