Query: Mining Interpretable Spatio-temporal Logic Properties for Spatially
  Distributed Systems   The Internet-of-Things, complex sensor networks, multi-agent cyber-physical
systems are all examples of spatially distributed systems that continuously
evolve in time. Such systems generate huge amounts of spatio-temporal data, and
system designers are often interested in analyzing and discovering structure
within the data. There has been considerable interest in learning causal and
logical properties of temporal data using logics such as Signal Temporal Logic
(STL); however, there is limited work on discovering such relations on
spatio-temporal data. We propose the first set of algorithms for unsupervised
learning for spatio-temporal data. Our method does automatic feature extraction
from the spatio-temporal data by projecting it onto the parameter space of a
parametric spatio-temporal reach and escape logic (PSTREL). We propose an
agglomerative hierarchical clustering technique that guarantees that each
cluster satisfies a distinct STREL formula. We show that our method generates
STREL formulas of bounded description complexity using a novel decision-tree
approach which generalizes previous unsupervised learning techniques for Signal
Temporal Logic. We demonstrate the effectiveness of our approach on case
studies from diverse domains such as urban transportation, epidemiology, green
infrastructure, and air quality monitoring.
