MASA: Motif-Aware State Assignment in Noisy Time Series Data [article]

Saachi Jain, David Hallac, Rok Sosic, Jure Leskovec
2019 arXiv   pre-print
We formulate the problem of motif discovery as a large optimization problem, which we solve using an expectation-maximization type approach.  ...  An important problem in this domain is to identify repeated sequences of states, known as motifs. Such motifs correspond to complex behaviors that capture common sequences of state transitions.  ...  Case Studies Here, we run CASC on two real-world examples, using automobile and aircraft sensor data to demonstrate how our approach can be applied to discover insightful motifs.  ...
