This paper explores potential parallels between the evolution of users’ interactions with visualization tools during data exploration and assumptions made in popular online learning techniques. Through a series of empirical analyses, we seek to answer the question: What are the best learning methods for modeling shifts in users’ data focus during EVA?

Missing data often exists in real-world datasets, requiring significant time and effort for imputation to learn accurate machine learning (ML) models. In this paper, we demonstrate that imputing all missing values is not always necessary to achieve an accurate ML model.

CertainPrep system checks this necessity efficiently with theoretical guarantees and returns accurate models in cases where imputation is unnecessary. This human-in-the-loop approach optimizes data preparation workflows.

Visualization Recommendation Systems help users discover important insights during data exploration. These systems should understand users’ exploration.
SIGMOD, 2024
Real-world data is often incomplete and contains missing values. To train accurate models over real-world datasets, users need to spend a substantial amount of time and resources.
AAAI, 2024
Exploratory visual analysis (EVA) is an essential stage of the data science pipeline, where users often lack clear analysis goals.
Conference, 2022
A known problem with training deep neural networks, mostly parameterized by connection weights at each layer, is that of finding an appropriate model complexity under the empirical risk minimization setting.
