Structured Extraction of Terms and Conditions from German and English Online Shops

1 code implementation ECNLP (ACL) 2022 Tobias Schamel, Daniel Braun, Florian Matthes

While content extraction, in general, is a well-researched field and many open source libraries are available, our evaluation shows, that existing solutions cannot extract Terms and Conditions in sufficient quality, mainly because of their special structure.

NLP for Consumer Protection: Battling Illegal Clauses in German Terms and Conditions in Online Shopping

no code implementations ACL (NLP4PosImpact) 2021 Daniel Braun, Florian Matthes

Government and non-government organisations (NGOs) for consumer protection battle such terms on behalf of consumers, who often hesitate to take on legal actions themselves.

Clause Topic Classification in German and English Standard Form Contracts

no code implementations ECNLP (ACL) 2022 Daniel Braun, Florian Matthes

So-called standard form contracts, i. e. contracts that are drafted unilaterally by one party, like terms and conditions of online shops or terms of services of social networks, are cornerstones of our modern economy.

N-QGN: Navigation Map from a Monocular Camera using Quadtree Generating Networks

no code implementations24 Feb 2022 Daniel Braun, Olivier Morel, Pascal Vasseur, Cédric Demonceaux

Monocular depth estimation has been a popular area of research for several years, especially since self-supervised networks have shown increasingly good results in bridging the gap with supervised and stereo methods.

3D Reconstruction Autonomous Navigation +1

Neural-Network Heuristics for Adaptive Bayesian Quantum Estimation

no code implementations4 Mar 2020 Lukas J. Fiderer, Jonas Schuff, Daniel Braun

Quantum metrology promises unprecedented measurement precision but suffers in practice from the limited availability of resources such as the number of probes, their coherence time, or non-classical quantum states.

SimpleNLG-DE: Adapting SimpleNLG 4 to German

1 code implementation WS 2019 Daniel Braun, Kira Klimt, Daniela Schneider, Florian Matthes

SimpleNLG is a popular open source surface realiser for the English language.

Improving the dynamics of quantum sensors with reinforcement learning

no code implementations22 Aug 2019 Jonas Schuff, Lukas J. Fiderer, Daniel Braun

Recently proposed quantum-chaotic sensors achieve quantum enhancements in measurement precision by applying nonlinear control pulses to the dynamics of the quantum sensor while using classical initial states that are easy to prepare.


Trade--off relations for operation entropy of complementary quantum channels

no code implementations9 Aug 2019 Jakub Czartowski, Daniel Braun, Karol Życzkowski

The entropy of a quantum operation, defined as the von Neumann entropy of the corresponding Choi-Jamio{\l}kowski state, characterizes the coupling of the principal system with the environment.

Hierarchical State Abstractions for Decision-Making Problems with Computational Constraints

no code implementations22 Oct 2017 Daniel T. Larsson, Daniel Braun, Panagiotis Tsiotras

In this semi-tutorial paper, we first review the information-theoretic approach to account for the computational costs incurred during the search for optimal actions in a sequential decision-making problem.

A Nonparametric Conjugate Prior Distribution for the Maximizing Argument of a Noisy Function

no code implementations NeurIPS 2012 Pedro Ortega, Jordi Grau-Moya, Tim Genewein, David Balduzzi, Daniel Braun

We propose a novel Bayesian approach to solve stochastic optimization problems that involve finding extrema of noisy, nonlinear functions.
