Open data for the crowd: an account of citizen science at ETH Library
(2019)LIBER QuarterlyThis paper gives an account of ETH Library’s combined strategy of implementing an open data policy and using crowdsourcing to improve metadata. Both activities go hand in hand and promote each other. ETH Library’s Image Archive was the first unit to provide content for free download in high resolution. This paved the way for a very successful crowdsourcing campaign during which citizen scientists located places, dated photographs, and ...Conference Paper -
Telling BERT's Full Story: from Local Attention to Global Aggregation
(2021)Proceedings of the 16th Conference of the European Chapter of the Association for Computational Linguistics: Main VolumeWe take a deep look into the behaviour of self-attention heads in the transformer architecture. In light of recent work discouraging the use of attention distributions for explaining a model’s behaviour, we show that attention distributions can nevertheless provide insights into the local behaviour of attention heads. This way, we propose a distinction between local patterns revealed by attention and global patterns that refer back to the ...Conference Paper -
Comparing Metrics for Scenario-based Robustness Assessment of Building Performance
(2021)Journal of Physics: Conference SeriesReaching Swiss greenhouse gas emission reduction goals for the building sector requires effective renovation strategies [1]. Due to the energy performance gap (EPG), the building stock might not be decarbonised as expected [2]. Uncertain boundary conditions such as occupant behaviour, climatic conditions, and characteristics of energy system components lead to inaccurate predictions of operational emissions and decarbonization pathways. ...Conference Paper -

Gaze and feet as additional input modalities for interacting with geospatial interfaces
(2016)ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesGeographic Information Systems (GIS) are complex software environments and we often work with multiple tasks and multiple displays when we work with GIS. However, user input is still limited to mouse and keyboard in most workplace settings. In this project, we demonstrate how the use of gaze and feet as additional input modalities can overcome time-consuming and annoying mode switches between frequently performed tasks. In an iterative ...Conference Paper -
Dependence of Crater Formation in Dry EDM on Electrical Breakdown Mechanism
(2016)Procedia CIRP ~ 18th CIRP Conference on Electro Physical and Chemical Machining (ISEM XVIII)The research effort in dry electrical discharge machining (DEDM) has increased during the last years. The process has advantages in comparison with EDM in oil-based dielectric media, such as low tool electrode wear, thin recast layers on the work piece surface and much more environmentally friendly conditions. However, the plasma-material surface interactions involved in dry EDM are not properly explained yet. Therefore, a characterization ...Conference Paper -
Influence of the anode material on the breakdown behavior in dry electrical eischarge machining
(2012)Procedia CIRP ~ Fifth CIRP Conference on High Performance Cutting 2012In the last years dry electrical discharge machining (DEDM) has been proposed as an alternative to the traditional EDM. The main reason for these efforts is the absence of a liquid dielectric which results in a simpler and environmentally friendly machine. This paper presents measurements of the material removal rate in function of different tool electrode and work piece material put in relation with the breakdown behavior of the process ...Conference Paper -
Mining Points-of-Interest for Explaining Urban Phenomena: A Scalable Variational Inference Approach
(2020)Proceedings of the World Wide Web Conference 2020 (WWW '20)Points-of-interest (POIs; i.e., restaurants, bars, landmarks, and other entities) are common in web-mined data: they greatly explain the spatial distributions of urban phenomena. The conventional modeling approach relies upon feature engineering, yet it ignores the spatial structure among POIs. In order to overcome this shortcoming, the present paper proposes a novel spatial model for explaining spatial distributions based on web-mined ...Conference Paper -
A Unified View on Bipartite Species-reaction Graphs and Their Relation to Interaction Graphs and Qualitative Dynamics of Chemical Reaction Networks
(2020)Electronic notes in theoretical computer science ~ Proceedings of SASB 2018, the Ninth International Workshop on Static Analysis and Systems BiologyThe Jacobian matrix of a dynamic system and its principal minors play a prominent role in the study of qualitative dynamics and bifurcation analysis. When interpreting the Jacobian as an adjacency matrix of an interaction graph, its principal minors reate to sets of disjoint cycles in this graph and conditions for qualitative dynamic behaviors can be inferred from its cycle structure. The Jacobian of chemical reaction systems decomposes ...Conference Paper -
