mage: Fluid Moves Between Code and Graphical Work in Computational Notebooks

We aim to increase the flexibility at which a data worker can choose the right tool for the job, regardless of whether the tool is a code library or an interactive graphical user interface (GUI). To achieve this flexibility, we extend computational notebooks with a new API mage, which supports tools that can represent…

Understanding and Visualizing Data Iteration in Machine Learning

Successful machine learning (ML) applications require iterations on both modeling and the underlying data. While prior visualization tools for ML primarily focus on modeling, our interviews with 23 ML practitioners reveal that they improve model performance frequently by iterating on their data (e.g., collecting new d…

Towards Effective Foraging by Data Scientists to Find Past Analysis Choices

Data scientists are responsible for the analysis decisions they make, but it is hard for them to track the process by which they achieved a result. Even when data scientists keep logs, it is onerous to make sense of the resulting large number of history records full of overlapping variants of code, output, plots, etc.…

The Story in the Notebook: Exploratory Data Science using a Literate Programming Tool

Literate programming tools are used by millions of programmers today, and are intended to facilitate presenting data analyses in the form of a narrative. We interviewed 21 data scientists to study coding behaviors in a literate programming environment and how data scientists kept track of variants they explored. For p…
