David and Goliath: An Empirical Evaluation of Attacks and Defenses for QNNs at the Deep Edge

2 code implementations8 Apr 2024 Miguel Costa, Sandro Pinto

To fill this gap, we empirically evaluate the effectiveness of attacks and defenses from (full-precision) ANNs on (constrained) QNNs.

Scoring Cycling Environments Perceived Safety using Pairwise Image Comparisons

1 code implementation25 Jul 2023 Miguel Costa, Manuel Marques, Felix Wilhelm Siebert, Carlos Lima Azevedo, Filipe Moura

Furthermore, this approach facilitates the continuous assessment of changing cycling environments, allows for a short-term evaluation of measures, and is efficiently deployed in different locations or contexts.

Shifting Capsule Networks from the Cloud to the Deep Edge

1 code implementation6 Oct 2021 Miguel Costa, Diogo Costa, Tiago Gomes, Sandro Pinto

In terms of throughput, our Arm Cortex-M API enables the execution of primary capsule and capsule layers with medium-sized kernels in just 119. 94 and 90. 60 milliseconds (ms), respectively (STM32H755ZIT6U, Cortex-M7 @ 480 MHz).

Non-minimal coupling contribution to DIS at low $x$ in Holographic QCD

1 code implementation20 Apr 2018 Artur Amorim, Robert Carcassés Quevedo, Miguel Costa

We consider the effect of including a non-minimal coupling between a $U(1)$ vector gauge field and the graviton Regge trajectory in holographic QCD models.

A Context Aware and Video-Based Risk Descriptor for Cyclists

no code implementations24 Apr 2017 Miguel Costa, Beatriz Quintino Ferreira, Manuel Marques

From smartphone sequences of images, this generic framework is able to automatically identify events considering different risk criteria based on the cyclist's motion and object detection.
