It's About Time: Analyzing, Forecasting, and Reasoning with Temporal Data
Wednesday, September 12, 1:15PM – 2:30PM
Temporal data is prevalent in virtually all scientific domains, and permeates societal phenomena as well---examples include computer and network logs, chronological history, political poll data, stock market information, and climate measurements. Common tasks involving time for these domains include determining causality, predicting future trends, and characterizing cyclic patterns. However, these tasks are often difficult to perform because temporal analysis commonly involves long periods of time, multiple parallel time series, and complex relationships and correlations. In this talk, I will review recent and ongoing work conducted in my research group on visual analytic methods to support these tasks. More specifically, I will present TraXplorer, a visualization system supporting multi-focus interaction of time-series data, as well as results on the graphical perception of temporal visualizations, our work on supporting temporal forecasting, and findings on how analysts use time when investigating complex sequences of events.
