Enabling the assessment of the uncertainty and allowing uncertainty-aware analysis, the uncertainty needs to be quantified initially. We address this challenge by formalizing the quantification of uncertainty for multivariate time series pre-processing. To tackle the large design space, we elaborate key considerations for quantifying and aggregating uncertainty. We provide an example how the quantified uncertainty is used in a multivariate time series pre-processing application to assess the effectiveness of pre-processing steps and adjust the pipeline to minimize the introduction of uncertainty.}, year = {2019}, journal = {EuroVis Workshop on Visual Analytics (EuroVA)}, month = {06/2019}, publisher = {The Eurographics Association}, address = {Porto, Portugal}, isbn = {978-3-03868-087-1}, doi = {10.2312/eurova.20191121}, }
