Review: A Symbolic Representation of Time Series, with Implications for Streaming Algorithms
In [1], the authors present a method for constructing a symbolic (nominal) representation for real-valued time series data. A symbolic representation is desirable because then it becomes possible to use many of the effective algorithms that require symbolic representation, like hashing and Markov models.
