Deep analysis definition
Deep analysis means the data are analyzed in detail at their finest granularity. In deep analysis we do not analyze just summary statistics or just the output of an automated data reduction algorithm or just random samples of the data; these practices carry with them a big risk of missing critical information in the data. Deep analysis includes starting an analysis with visualization of both detailed data at their finest granularity and summary statistics, and continuing visualization throughout the whole course of the analysis [7]. Deep analysis is done routinely today for many smaller datasets. The goal of D&R and Tessera is to extend deep analysis to much larger and more complex data.
