Composite Relationship Fields with Transformers for Scene Graph Generation

Alexandre Massoud Alahi, George Adaimi, David Mizrahi

Scene graph generation (SGG) methods extract relationships between objects. While most methods focus on improving top-down approaches, which build a scene graph based on detected objects from an off-the-shelf object detector, there is a limited amount of w ...

Cross Modal Focal Loss for RGBD Face Anti-Spoofing

Sébastien Marcel

Automatic methods for detecting presentation attacks are essential to ensure the reliable use of facial recognition technology. Most of the methods available in the litera- ture for presentation attack detection (PAD) fails in gen- eralizing to unseen atta ...

Einsatz von Nichtmarktstrategien durch oeffentliche Unternehmen gegenueber dem Staat : Untersuchung am Beispiel der Schweizerischen Post AG

Carole Juliane Isabelle Rentsch

Public enterprises operate in the area between the opposing poles of state and market. On the one hand they must meet a wide range of political expectations, and on the other they must fulfil commercial efficiency criteria. This dissertation addresses how ...

Optimal Investment and Premium Policies Under Risk Shifting and Solvency Regulation

Damir Filipovic

Limited liability creates an incentive for insurers to increase the risk of the assets and liabilities at the expense of policyholders. We show that solvency capital requirements restrict the set of feasible investment and premium policies and can thereby ...

On Rendering Synthetic Images for Training an Object Detector

Pascal Fua, Vincent Lepetit, Artem Rozantsev

We propose a novel approach to synthesizing images that are effective for training object detectors. Starting from a small set of real images, our algorithm estimates the rendering parameters required to synthesize similar images given a coarse 3D model of ...

A microfluidic flow-cell for the study of the ultrafast dynamics of biological systems

Majed Chergui, Adrien Alexis Paul Chauvet

The study of biochemical dynamics by ultrafast spectroscopic methods is often restricted by the limited amount of liquid sample available, while the high repetition rate of light sources can induce photodamage. In order to overcome these limitations, we de ...

Piecewise non-linear constant life diagram formulation for FRP composite materials

Thomas Keller, Anastasios Vassilopoulos, Behzad Dehghan Manshadi

A new formulation for predicting an asymmetric, piecewise non-linear constant life diagram (CLD) is introduced in this paper. The development of the new model is based on the representation of the fatigue data on the stress ratio (R)-stress amplitude (σa) ...

A Dynamically Constrained Genetic Algorithm For Hardware-software Partitioning

Pierre-André Mudry, Guillaume Zufferey

In this article, we describe the application of an enhanced genetic algorithm to the problem of hardware-software codesign. Starting from a source code written in a high-level language our algorithm determines, using a dynamically-weighted fitness function ...
