Query: Building pattern recognition applications with the SPARE library   This paper presents the SPARE C++ library, an open source software tool
conceived to build pattern recognition and soft computing systems. The library
follows the requirement of the generality: most of the implemented algorithms
are able to process user-defined input data types transparently, such as
labeled graphs and sequences of objects, as well as standard numeric vectors.
Here we present a high-level picture of the SPARE library characteristics,
focusing instead on the specific practical possibility of constructing pattern
recognition systems for different input data types. In particular, as a proof
of concept, we discuss two application instances involving clustering of
real-valued multidimensional sequences and classification of labeled graphs.
