Pretraining boosts out-of-domain robustness for pose estimation

Alexander Mathis, Mackenzie Mathis, Steffen Schneider, Matthias Bethge, Thomas Ray Biasi, Mert Yüksekgönül

Neural networks are highly effective tools for pose estimation. However, as in other computer vision tasks, robustness to out-of-domain data remains a challenge, especially for small training sets that are common for real-world applications. Here, we probe ...

Template Induction over Unstructured Email Corpora

Julia Proskurnia

Unsupervised template induction over email data is a central component in applications such as information extraction, document classification, and auto-reply. The benefits of automatically generating such templates are known for structured data, e.g. mach ...

Profiling, Modelling and Facilitating Online Activism

Julia Proskurnia

The extensive and successful use of social media has enhanced and empowered a variety of movements all over the world in a way that is hard to achieve through conventional means. This has led to numerous studies that leverage online social data to describe ...

Reconstruction of 3D scattered data via radial basis functions by efficient and robust techniques

Alberto Crivellaro

We propose new algorithms to overcome two of the most constraining limitations of surface reconstruction methods in use. In particular, we focus on the large amount of data characterizing standard acquisitions by scanner and the noise intrinsically introdu ...

JammJoint: A Variable Stiffness Device Based on Granular Jamming for Wearable Joint Support

Auke Ijspeert, Jamie Paik, Simon Lukas Hauser, Matthew Aaron Robertson

In robotics, controlling the stiffness of the joints that contribute to the robots’ degree of freedom dictates the adaptability, versatility, and safety of the whole system.We can achieve variable stiffness or impedance in a robotic system purely by the co ...

Towards a Principled Approach to Humanitarian Information and Communication Technology

Denis Gillet, Isabelle Barbara Marie-Hélène Cardia, Adrian Christian Holzer

The humanitarian sector is entering in the network age. The explosion in access to new information and communication technology (ICT) like mobile phones, the internet, and social media, is changing the way people communicate in emergency situations. Howeve ...

Remotely Controlled Isomer Selective Molecular Switching

Klaus Kern, Uta Schlickum, Hagen Klauk, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Non local addressing-the "remote control"- of molecular switches promises more efficient processing for information technology, where fast speed of switching is essential. The surface state of the (111) facets of noble metals, a confined two-dimensional el ...

Admissible geometrical domains and graphic statics to evaluate constitutive elements of structural robustness

Corentin Jean Dominique Fivet

Structural robustness is related to the insensitivity of a structure to local failure, which is linked to the ability of force redistribution. Current approaches—probabilistic, risk-based, deterministic, and energetic—are poorly suited to inform the design ...

Nonlinear Eigenvalue Problems With Specified Eigenvalues

Daniel Kressner

This work considers eigenvalue problems that are nonlinear in the eigenvalue parameter. Given such a nonlinear eigenvalue problem T, we are concerned with finding the minimal backward error such that T has a set of prescribed eigenvalues with prescribed al ...

Stochastic Exploration of Ambiguities for Non-Rigid Shape Recovery

Pascal Fua

Recovering the 3D shape of deformable surfaces from single images is known to be a highly ambiguous problem because many different shapes may have very similar projections. This is commonly addressed by restricting the set of possible shapes to linear comb ...

Modeling Value Creation and Capture in Service Systems

Alain Wegmann, Arash Golnam, Vijay Viswanathan

In service-dominant (S-D) logicvalue is viewed as being co-created between companies, customers, and other actors within a service system. In order to understand how service systems maintain their viability and competitiveness, two fundamental questions sh ...

Design Methods and Tools for 3D Integration

Giovanni De Micheli, David Atienza Alonso, Yusuf Leblebici, Vasileios Pavlidis

The design of 3-dimensional integrated circuits requires new specialized tools, methods and flows. Whereas some tools are on the market and some design flows for standard ICs are extended to handle die stacking and through-silicon vias, much R&D has still ...

AntispamLab - A Tool for Realistic Evaluation of Email Spam Filters

Jean-Yves Le Boudec, Slavisa Sarafijanovic, Raphaël Naefen, Luis Hernandez

The existing tools for testing spam filters evaluate a filter instance by simply feeding it with a stream of emails, possibly also providing a feedback to the filter about the correctness of the detection. In such a scenario the evaluated filter is disconn ...
