“…In situ analysis algorithms may transform data into reduced representations or surrogate models in order to mitigate large data size, high dimensionality, or long computation times. Low-rank approximation (Austin et al, 2016), statistical summarization (Biswas et al, 2018;Dutta et al, 2017;Hazarika et al, 2018;Lawrence et al, 2017;Lohrmann et al, 2017;Thompson et al, 2011), topological segmentation (Gyulassy et al, 2012(Gyulassy et al, , 2019Landge et al, 2014;Weber, 2013, 2014), wavelet transformation (Li et al, 2017;Salloum et al, 2018), lossy compression (Brislawn et al, 2012;Di and Cappello, 2016;Lindstrom, 2014), geometric modeling (Nashed et al, 2019; Peterka et al, 2018), and feature detection (Guo et al, 2017) may be used to generate reduced or surrogate models.…”
