    A Visual Analytics Approach for Exploration of High-Dimensional Time Series Based on Neighbor-Joining Tree
    (2018) Roberto Rodríguez Urquiaga; Reynaldo Alfonte Zapana; Ana María Cuadros Valdivia
    High-dimensional time series analysis through visual techniques poses many challenges due to the visualization solutions proposed until now for exploratory tasks are not well-oriented to high volume of data. When the data sets grow large, the visual alternatives do not allow for a good association between similar time series. With the aim to increase more alternatives, we introduce a visual analytic approach based on Neighbor-Joining similarity tree. The proposed approach internally consists of five time series dimension reduction techniques widely used, two well-known similarity measures and interaction mechanisms to do exploratory analysis of high-dimensional time series data interactively.
