Broad Discourse Context for Language Modeling
(2017)Recurrent neural network language models (RNNLM) have become a key element for state-of-the-art language modeling and are integral parts in a wide range of applications such as speech recognition or information retrieval systems. However, recent work has shown that the extent to which these models truly understand language remains unclear. In particular, the LAMBADA dataset consists of a collection of hard word prediction examples ...Master Thesis -

Design and Implementation of RDMA-based Database Operators
(2017)In this thesis, we present a novel, extensible RDMA database operator interface — where RDMA is not simply the acronym for Remote Direct Memory Accesses – in addition it also stands for Reusable, Distributed MAin-memory database operator interface. The interface is designed and implemented for distributed query pipelines scaling up algorithms to many thousand cores. It provides the usability of SQL, combined with the expressiveness and ...Master Thesis -
Search for Invisible Decay Channels of Positronium Confined in a Vacuum Cavity
(2017)The origin and nature of Dark Matter is a question of great importance for cosmology and particle physics. The Standard Model (SM) of Particle Physics cannot provide a viable candidate and while several theoretical models have been proposed, none have been confirmed experimentally. Among these models, a very interesting one is the extension of the Standard Model with a hidden sector. A particular example is the Mirror Sector, which consists ...Doctoral Thesis -
Adversarial perturbations and deformations for convolutional neural networks
(2017)We investigate the robustness of convolutional neural networks for image classification in terms of adversarial examples. We compare a widely used network for handwritten digit classification to a more robust classifier based on a feature extractor with predefined wavelet filters. In addition to generating adversarial examples by adding small perturbations to the input images, we introduce the concept of adversarial deformations of images. ...Master Thesis -

Growth and Bioactive Properties of Native Potatoes under Drought Stress - Development of an Integrated Approach from the Field to the Market
(2017)The aim of this doctorate was to explore the potential contribution to food security of ancient genetic resources of crops, from the field to the market. Special attention was given to the resistance to drought stress, in the context of climate change, and to the production of bioactives potentially useful for human health. This project encompassed a broad diversity of topics, from fundamental sciences to social sciences, and was constructed ...Doctoral Thesis -

Towards Communication in CAAD
(2017)This work deals with computational models in architecture, with the ambition of accomplishing three objectives: 1. To position the established computational models in architecture within the broader context of mathematical and computational modelling. 2. To challenge computational models in architecture by the contemporary modelling approaches, in which computation is regarded from the perspective of communication between different ...Doctoral Thesis
