text: 'Cyber-physical systems (CPS) and the Internet-of-Things (IoT) result in a
tremendous amount of generated, measured and recorded time-series data. Extracting
temporal segments that encode patterns with useful information out of these huge
amounts of data is an extremely difficult problem. We propose shape expressions
as a declarative formalism for specifying, querying and extracting sophisticated
temporal patterns from possibly noisy data. Shape expressions are regular expressions
with arbitrary (linear, exponential, sinusoidal, etc.) shapes with parameters
as atomic predicates and additional constraints on these parameters. We equip
shape expressions with a novel noisy semantics that combines regular expression
matching semantics with statistical regression. We characterize essential properties
of the formalism and propose an efficient approximate shape expression matching
procedure. We demonstrate the wide applicability of this technique on two case
studies. '
