Revisiting microbe-metabolite interactions: doing better than random
(2019)bioRxivRecently, Quinn and Erb et al [1] made the case that when used correctly, correlation and proportionality can outperform MMvec when identifying microbe-metabolite interactions. We revisit this comparison and show that the proposed correlation and proportionality are outperformed by MMvec on real data due to their inability to deal with sparsity commonly observed in microbiome and metabolome datasets.Working Paper -
Meta Answering for Machine Reading
(2019)arXivWe investigate a framework for machine reading, inspired by real world information-seeking problems, where a meta question answering system interacts with a black box environment. The environment encapsulates a competitive machine reader based on BERT, providing candidate answers to questions, and possibly some context. To validate the realism of our formulation, we ask humans to play the role of a meta-answerer. With just a small snippet ...Working Paper -
Procedure and methods for the assessment of greenhouse gas emissions of flights at ETH Zurich
(2019)ETH Zurich committed to reducing greenhouse gas (GHG) emissions from air travel by 11% in the next few years. The reduction shall be in addition to reductions achieved by the aviation industry. Flights taken by ETH’s employees and guests are included if they are paid for by ETH. Flights taken by ETH students are also considered, if they are part of their curriculum. Strategies for reducing emissions include avoiding air travel by increased ...Report -
Towards an Inclusive Future in AI
(2019)In response to the accelerating potential of artificial intelligence (AI) to transform our lives, various governments, multilateral bodies, and other organizations have produced high-level principles and guidelines for the ethical use of AI in recent years. Despite the staggering number of such documents (over 90 by October 2019), there appears to be a relatively high degree of convergence on the level of principles. «Inclusiveness» is ...Report -
Strong structural controllability of signed networks
(2019)arXivIn this paper, we discuss the controllability of a family of linear time-invariant (LTI) networks defined on a signed graph. In this direction, we introduce the notion of positive and negative signed zero forcing sets for the controllability analysis of positive and negative eigenvalues of system matrices with the same sign pattern. A sufficient combinatorial condition that ensures the strong structural controllability of signed networks ...Working Paper -
Treibhausgas-Emissionen aus Dienstreisen der ETH Zürich 2017–2018
(2019)Die vorliegende Zusammenfassung der Treibhausgas-Emissionen aus Dienstreisen der ETH Zürich zeigt die wichtigsten Emissionszahlen und Auswertungen. Erfasst in diesem Bericht sind alle Dienstreisen der Angestellten der ETH Zürich sowie die Flugreisen der Gäste der ETH Zürich, sofern die Reisekosten von der ETH Zürich übernommen wurden. Nicht erfasst sind Reisen von Studierenden im Rahmen ihres Studiums (Studienreisen), Pendlerbewegungen ...Report -
Development and testing of scenarios for implementing Holocene LULC in Earth System Model Experiments
(2019)Geoscientific Model Development DiscussionsAnthropogenic changes in land use and land cover (LULC) during the pre-industrial Holocene could have affected regional and global climate. Current LULC scenarios are based on relatively simple assumptions and highly uncertain estimates of population changes through time. Archaeological and palaeoenvironmental reconstructions have the potential to refine these assumptions and estimates. The Past Global Changes (PAGES) LandCover6k initiative ...Working Paper -
How to include non-CO2 climate change contributions of air travel at ETH Zurich
(2019)In addition to emitting carbon dioxide, aircraft operation in the upper troposphere and lower stratosphere alter the atmospheric concentration of greenhouse gases such as ozone and methane, trigger the formation of condensation trails (contrails) and increase cirrus cloudi-ness (IPCC 1999). This leads aircraft to have higher climate change contributions than what would be expected when considering only their fuel consumption or CO2 emissions ...Report -
Falschübersetzungen?
(2019)Die automatische Übersetzung natürlicher Sprachen hat in letzter Zeit zwar grosse Fortschritte gemacht, sie ist aber nach wie vor mangelhaft. So gibt es, wie dieser Bericht zeigt, Schwierigkeiten bei der Erkennung von Verbformen (2. Person Einzahl und Mehrzahl, Höflichkeitsform). Das wirkt sich vor allem bei der Übertragung in die Sprachen Französisch, Italienisch und Spanisch aus. Die Programme erkennen zudem offensichtliche Fehler im ...Working Paper -
