Simulation-Based Optimization of User Interfaces for Quality-Assuring Machine Learning Model Predictions
This addresses the labor-intensive nature of quality assurance for machine learning predictions, offering a scalable alternative to user studies for interface optimization.
The paper tackles the problem of optimizing user interfaces for quality assurance in machine learning by proposing a simulation-based method to reduce interaction costs, demonstrating its application in several QA4ML scenarios.
Quality-sensitive applications of machine learning (ML) require quality assurance (QA) by humans before the predictions of an ML model can be deployed. QA for ML (QA4ML) interfaces require users to view a large amount of data and perform many interactions to correct errors made by the ML model. An optimized user interface (UI) can significantly reduce interaction costs. While UI optimization can be informed by user studies evaluating design options, this approach is not scalable because there are typically numerous small variations that can affect the efficiency of a QA4ML interface. Hence, we propose using simulation to evaluate and aid the optimization of QA4ML interfaces. In particular, we focus on simulating the combined effects of human intelligence in initiating appropriate interaction commands and machine intelligence in providing algorithmic assistance for accelerating QA4ML processes. As QA4ML is usually labor-intensive, we use the simulated task completion time as the metric for UI optimization under different interface and algorithm setups. We demonstrate the usage of this UI design method in several QA4ML applications.
