These middlemen between data and decision makers may induce cost and trust issues in the generated visualizations. To overcome these issues, I envision a future scenario where intelligent interactive visualization systems may replace analysts in the decision-making process when the analyses and visualizations are relatively simple. However, three gaps need to be addressed before the future scenario could be realized. In this paper, I will discuss these gaps, propose potential solutions, and hope to raise a discussion on the future role of visualization systems for data-driven decision-making.","PeriodicalId":150871,"journal":{"name":"2022 IEEE Workshop on TRust and EXpertise in Visual Analytics (TREX)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124036485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Mixed-Initiative System for Contextualized Fairness Assessment","authors":"Rareş Constantin, Moritz Dück, Anton Alexandrov, Patrik Matošević, Daphna Keidar, Mennatallah El-Assady","doi":"10.1109/TREX57753.2022.00005","DOIUrl":"https://doi.org/10.1109/TREX57753.2022.00005","url":null,"abstract":"Fairness evaluation presents a challenging problem in machine learning, and is usually restricted to the exploration of various metrics that attempt to quantify algorithmic fairness. However, due to cultural and perceptual biases, such metrics are often not powerful enough to accurately capture what people perceive as fair or unfair. To close the gap between human judgement and automated fairness evaluation, we develop a mixed-initiative system named FairAlign, where laypeople assess the fairness of different classification models by analyzing expressive and interactive visualizations of data. Using the aggregated qualitative feedback, data scientists and machine learning experts can examine the similarities and the differences between predefined fairness metrics and human judgement in a contextualized setting. To validate the utility of our system, we conducted a small study on a socially relevant classification task, where six people were asked to assess the fairness of multiple prediction models using the provided visualizations. The results show that our platform is able to give valuable guidance for model evaluation in case of otherwise contradicting and indecisive metrics for algorithmic fairness.","PeriodicalId":150871,"journal":{"name":"2022 IEEE Workshop on TRust and EXpertise in Visual Analytics (TREX)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the automated analysis of these data, machine learning approaches yield promising results. However, due to their black-box nature, such approaches are often mistrusted by clinicians. We propose gaitXplorer, a visual analytics approach for the classification of CP-related gait patterns that integrates Grad-CAM, a well-established explainable artificial intelligence algorithm, for explanations of machine learning classifications. Regions of high relevance for classification are highlighted in the interactive visual interface. The approach is evaluated in a case study with two clinical gait experts. They inspected the explanations for a sample of eight patients using the visual interface and expressed which relevance scores they found trustworthy and which they found suspicious. Overall, the clinicians gave positive feedback on the approach as it allowed them a better understanding of which regions in the data were relevant for the classification.","PeriodicalId":150871,"journal":{"name":"2022 IEEE Workshop on TRust and EXpertise in Visual Analytics (TREX)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129463058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
