Symbol Extraction Method and Symbolic Distance for Analysing Medical Time Series [chapter]

Fernando Alonso, Loïc Martínez, Aurora Pérez, Agustín Santamaría, Juan Pedro Valente
2006 Lecture Notes in Computer Science  
This paper focuses on the process of transforming numerical time series into a symbolic domain and on the definition of both this domain and a distance for comparing symbolic temporal sequences.  ...  Most of the approaches that address this problem are based on numerical algorithms that calculate distances, clusters, index trees, etc.  ...  Transposition-based distances use the transposition of the sequence elements.  ...
