Visual analytics techniques for large multi-attribute time series data

Time series data commonly occur when variables are monitored over time. Many real-world applications involve the comparison of long time series across multiple variables (multi-attributes). Often business people want to compare this year’s monthly sales with last year’s sales to make decisions. Data warehouse administrators (DBAs) want to know their daily data loading job performance.

Integrated visual analysis of patterns in time series and text data - Workflow and application to financial data analysis

In this article, we describe a workflow and tool that allows a flexible formation of hypotheses about text features and their combinations, which are significantly connected in time to quantitative phenomena observed in stock data. To support such an analysis, we combine the analysis steps of frequent quantitative and text-oriented data using an existing a priori method. First, based on heurist...

Distribution Based Data Filtering for Financial Time Series Forecasting

Changes in the distribution of financial time series, particularly stock market prices, can happen at a very high frequency. Such changes make the prediction of future behavior very challenging. Application of traditional regression algorithms in this scenario is based on the assumption that all data samples are equally important for model building. Our work examines the use of an alternative d...
