The Northeastern University Visualization Consortium (NUVis) cordially invites you to join us for the next talk in our invited speakers series: “Interactive network visualizations for reasoning, communication, and collaboration” Prof. Cody Dunne College of Computer and Information Science, Northeastern University Friday, February 3, 2017 10:30-11:30am Snell Library 90, Northeastern University 360 Huntington Ave Boston MA, 02115 Coffee and pastries will be served. NEW: Attendees are invited to join the speaker for a brown bag lunch following the event. Bring your own lunch and more questions for the speaker to Snell 269A from 12 - 1 PM. (To find Snell 269A, take the stairs to the second floor and cut straight through the library from the floor entrance, past the 3D Printing Studio.) Abstract: The modern world is awash in complex data that can contain the keys to improving our lives. The scope of this data has rapidly outpaced our capabilities to analyze and comprehend, so we turn to computers to help. However, state-of-the-art technology can only supplement the human element. People assist in each stage of data science, whether it's data cleaning, understanding algorithm design, exploring computed results, or collaborating and sharing for decision-making. To present complex information to humans, we use visualizations that leverage our extraordinary perceptual system which can detect trends, clusters, gaps, and outliers almost instantly. A challenging and increasingly important type of data is networks of entities and their relationships. Networks have been are widely used across diverse disciplines to reason about complex behavior. These analyses involve understanding relationships, as well as associated attributes, statistics, or groupings. The omnipresent node-link visualization excels at showing topology and features simultaneously, but many are difficult to extract meaning from due to poor layout or shoehorning inherent complexity into limited space. The first part of my talk will detail techniques for measuring the readability of node-link visualizations and strategies to help users create more effective and understandable visualizations. Moreover, analyses of complex data often requires several sessions, and when returning later it can be difficult to recall the steps in your workflow. Data science in many domains is also highly collaborative. Multiple analysts may be working alongside stakeholders with varying expertise and time constraints. The second part of my talk addresses these needs, and I introduce visualization strategies that assist in making analysis workflows repeatable, free of errors, understandable, and easily shareable. About the speaker: Professor Cody Dunne works at the intersection of information visualization, network science, human-computer interaction, and computer science. He focuses on techniques for making data easier to analyze and share, as well as the application of visualization techniques to real-world problems. Dr. Dunne is currently researching ways to improve the readability of network visualizations as well as developing the next generation of tools for visually exploring, sharing, and collaborating around data and analysis workflows. Some domains Dr. Dunne has worked on include visualizing concepts from medical records, the spread of infectious diseases, citations in academic literature, interactions of people and organizations, relationships in archaeological dig sites, news term co-occurrence, thesaurus category relationships, municipal energy use, and computer network traffic flow. Prior to joining Northeastern, Dr. Dunne was a research scientist in IBM Watson Health, IBM Watson, and IBM Research. Dr. Dunne received his PhD and MS degrees in computer science under Ben Shneiderman at the University of Maryland Human-Computer Interaction Lab in 2013 and 2009, respectively. He earned a B.A. degree in computer science and mathematics from Cornell College in 2007. About NUVis: The Northeastern University Visualization Consortium (NUVis)<http://nuvis.neu.edu> is a new interdisciplinary cross-university initiative to support the university’s research efforts in visualization and to connect faculty, researchers, and students across campus to foster a visualization community. Northeastern University’s interdisciplinary focus and structure is an ideal environment for such an interdisciplinary field of study, and the goal of NUVis, funded through a collaboration between the College of Arts, Media and Design and the College of Computer and Information Science, is to continue to foster and grow this important area of research. NUVis sponsors talks and symposia including a bi-weekly seminar, connects faculty and students through its online portal, provides resources to support visualization related research at the university through avenues including workshops and library sponsored open office hours, and hosts and organizes community building events including hackathons and student research poster exhibitions.including workshops and library sponsored open office hours, and hosts and organizes community building events including hackathons and student research poster exhibitions. ######################################################################## To unsubscribe from the NUVIS-LIST list, click the following link: https://listserv.neu.edu/cgi-bin/wa?SUBED1=NUVIS-LIST
