Human-Centered Visual Analytics for Data and Model Understanding
Overview
Abstract
Visual Analytics integrates human visual perception and reasoning with computational analysis to enhance data exploration and decision-making. It enables users to navigate complex datasets, uncover hidden patterns, and make more informed and confident conclusions. Beyond data exploration, visual analytics can also provide deeper insights into machine learning (ML) models, revealing model behavior, performance differences, and potential biases. However, a key challenge remains: how can we design visual analytics systems that are truly user-centric, empowering domain experts to explore data and models, perform analytical reasoning, and compare models more effectively and efficiently? In this talk, I will first highlight how visual analytics for automated model discovery differs from traditional visual analytics approaches in machine learning. I will then focus on the design of intuitive and novel visualizations that help domain experts gain a richer and more meaningful understanding of their data and models. Finally, I will present several case studies from data science applications that demonstrate the applicability and effectiveness of visual analytics in supporting data and model exploration, analysis, and comparison.
