Talbot, Justin, Lee, Bongshin, Kapoor, Ashish and Tan, Desney S. (2009): EnsembleMatrix: interactive visualization to support machine learning with multiple classifiers. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 1283-1292. Available online

“Machine learning is an increasingly used computational tool within human-computer interaction research. While most researchers currently utilize an iterative approach to refining classifier models and performance, we propose that ensemble classification techniques may be a viable and even preferable alternative. In ensemble learning, algorithms combine multiple classifiers to build one that is superior to its components. In this paper, we present EnsembleMatrix, an interactive visualization system that presents a graphical view of confusion matrices to help users understand relative merits of various classifiers. EnsembleMatrix allows users to directly interact with the visualizations in order to explore and build combination models. We evaluate the efficacy of the system and the approach in a user study. Results show that users are able to quickly combine multiple classifiers operating on multiple feature sets to produce an ensemble classifier with accuracy that approaches best-reported performance classifying images in the CalTech-101 dataset.”

Lee, Bongshin, Smith, Greg, Robertson, George G., Czerwinski, Mary and Tan, Desney S. (2009): FacetLens: exposing trends and relationships to support sensemaking within faceted datasets. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 1293-1302. Available online

“Previous research has shown that faceted browsing is effective and enjoyable in searching and browsing large collections of data. In this work, we explore the efficacy of interactive visualization systems in supporting exploration and sensemaking within faceted datasets. To do this, we developed an interactive visualization system called FacetLens, which exposes trends and relationships within faceted datasets. FacetLens implements linear facets to enable users not only to identify trends but also to easily compare several trends simultaneously. Furthermore, it offers pivot operations to allow users to navigate the faceted dataset using relationships between items. We evaluate the utility of the system through a description of insights gained while experts used the system to explore the CHI publication repository as well as a database of funding grant data, and report a formative user study that identified usability issues.”

Robbins, Daniel C., Lee, Bongshin and Fernandez, Roland (2008): TapGlance: designing a unified smartphone interface. In: Proceedings of DIS08 Designing Interactive Systems 2008. pp. 386-394. Available online

“The difference between using one mobile phone and another can feel like learning a new language based on our extensive experience designing mobile applications for spatial data navigation, faceted search, and glanceable information, we have developed design principles for unifying the various aspects of the internet connected mobile phone ("smartphone") user experience. This paper presents TapGlance, a design proposal for a novel mobile phone user interface. TapGlance adapts its presentation to different levels of user attention, provides ubiquitous faceted search, and uses a zooming metaphor to unite inter- and intra-application navigation. Because our interface relies on a spatial metaphor it can also be adapted to non-textual representations and thus useful to broader populations. This paper describes our design goals, design process, and the resulting TapGlance design.”

Kim, Bohyoung, Lee, Bongshin and Seo, Jinwook (2007): Visualizing set concordance with permutation matrices and fan diagrams. In Interacting with Computers, 19 (5) pp. 630-643

“Scientific problem solving often involves concordance (or discordance) analysis among the result sets from different approaches. For example, different scientific analysis methods with the same samples often lead to different or even conflicting conclusions. To reach a more judicious conclusion, it is crucial to consider different perspectives by checking concordance among those result sets by different methods. In this paper, we present an interactive visualization tool called ConSet, where users can effectively examine relationships among multiple sets at once. ConSet provides an overview using an improved permutation matrix to enable users to easily identify relationships among sets with a large number of elements. Not only do we use a standard Venn diagram, we also introduce a new diagram called Fan diagram that allows users to compare two or three sets without any inconsistencies that may exist in Venn diagrams. A qualitative user study was conducted to evaluate how our tool works in comparison with a traditional set visualization tool based on a Venn diagram. We observed that ConSet enabled users to complete more tasks with fewer errors than the traditional interface did and most users preferred ConSet.”

“Networks have remained a challenge for information retrieval and visualization because of the rich set of tasks that users want to accomplish. This paper demonstrates a tool, NetLens, to explore a Content-Actor paired network data model. The NetLens interface was designed to allow users to pose a series of elementary queries and iteratively refine visual overviews and sorted lists. This enables the support of complex queries that are traditionally hard to specify in node-link visualizations. NetLens is general and scalable in that it applies to any dataset that can be represented with our abstract Content-Actor data model.”

“PaperLens is a novel visualization that reveals trends, connections, and activity throughout a conference community. It tightly couples views across papers, authors, and references. PaperLens was developed to visualize 8 years (1995-2002) of InfoVis conference proceedings and was then extended to visualize 23 years (1982-2004) of the CHI conference proceedings. This paper describes how we analyzed the data and designed PaperLens. We also describe a user study to focus our redesign efforts along with the design changes we made to address usability issues. We summarize lessons learned in the process of design and scaling up to the larger set of CHI conference papers.”
