Preferred monitor gamma setting is compared between normal and 10%-transmittance transparent display by simulating indoor lighting condition using LCD monitor. Four test images are manipulated to have 10 different monitor gamma values both for normal and transparent display. Based on 10 observers' judgment, it is found that lower gamma setting is preferred for transparent display than that for normal display. The preferred gamma settings for normal and transparent display have the similar lightness difference between gray levels.
Outcome-based predictive process monitoring deals with predicting the outcomes of running cases in a business process using feature vectors extracted from completed traces in an event log. Traditionally, in outcome-based predictive monitoring, a different model is developed using a bucket containing different types of feature vectors. This allows us to extend the traditional evaluation of the quality of process outcome predictions models beyond simply measuring the overall performance, developing a quality assessment framework based on three metrics: one considering the overall performance on all feature vectors, one considering the different levels of performance achieved on feature vectors belonging to individual buckets, i.e., the stability of the performance across buckets, and one considering the stability of the individual predictions obtained, accounting for how close the predicted probabilities are to the cutoff thresholds used to determine the predicted labels. The proposed metrics allow to evaluate, given a set of alternative designs, i.e., combinations of classifier and bucketing method, the quality of the predictions of each alternative. For this evaluation, we suggest using either the concept of Pareto-optimality or a scenariobased scoring method. We discuss an evaluation of the proposed framework conducted with real-life event logs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
