Multiresolution Motif Discovery in Time Series

V – Experimental Analysis
Scalability Experiments
• Dataset:
• Reproduced from Mueen et al., 2009*.
• 10 different sets of random walk time series
• Each set with 10000 up to 100000 series of length 1024
• About 8GB of time series data
• We compare MrMotif to Random Projection (Chiu et al.,
2003)
• Due to its popularity
• Is the basis of many current motif discovery approaches
• We also compare Space-Saving (SS) and Full Memory
(FM) versions of MrMotif
