On the Limitations of Model Stealing with Uncertainty Quantification Models
ESANN 2023 proceesdings, 2023 Model stealing aims at inferring a victim model's functionality at a fraction of the original training cost. While the goal is clear, in practice the model's architecture, weight dimension, and original training data can not be determined exactly, leading to mutual uncertainty during stealing.

The quantification of midwifery research: Limiting midwifery knowledge
Birth, 2022 AbstractAs two academics researching in the area of maternal health, we are increasingly concerned with what we see as a positivist turn in midwifery research. In this paper, we examine this idea of the quantification of midwifery research, using as an example the current esteem given to the systematic literature review, and its creep into other ...

Theoretical limitations of quantification for noncompetitive sandwich immunoassays [PDF]
Analytical and Bioanalytical Chemistry, 2015 Immunoassays exploit the highly selective interaction between antibodies and antigens to provide a vital method for biomolecule detection at low concentrations. Developers and practitioners of immunoassays have long known that non-specific binding often restricts immunoassay limits of quantification (LOQs). Aside from non-specific binding, most efforts

Diffraction-limited molecular cluster quantification with Bayesian nonparametrics [PDF]
Nature Computational Science, 2020 Abstract Life’s fundamental processes involve multiple molecules operating in close proximity within cells. To probe the composition and kinetics of molecular clusters confined within small (diffraction-limited) regions, experiments often report on the total fluorescence intensity simultaneously emitted from labeled molecules confined ...

Limits to the quantification of local climate change [PDF]
Environmental Research Letters, 2015 We demonstrate how the fundamental timescales of anthropogenic climate change limit the identification of societally relevant aspects of changes in precipitation. We show that it is nevertheless possible to extract, solely from observations, some confident quantified assessments of change at certain thresholds and locations. Maps of such changes, for a

Quantification – Affordances and Limits
Scholarly Assessment Reports, 2020 We live in a world awash in numbers. Tables, graphs, charts, Fitbit readouts, spreadsheets that overflow our screens no matter how large, economic forecasts, climate modeling, weather predictions, journal impact factors, H-indices, and the list could go on and on, still barely scratching the surface.

Quantification of the Information Limit of Transmission Electron Microscopes [PDF]
Physical Review Letters, 2008 The resolving power of high-resolution transmission electron microscopes is characterized by the information limit, which reflects the size of the smallest object detail observable with a particular instrument. We introduce a highly accurate measurement method for the information limit, which is suitable for modern aberration-corrected electron ...
