Query: Generalized Rational Variable Projection With Application in ECG
  Compression   In this paper we develop an adaptive transform-domain technique based on
rational function systems. It is of general importance in several areas of
signal theory, including filter design, transfer function approximation, system
identification, control theory etc. The construction of the proposed method is
discussed in the framework of a general mathematical model called variable
projection. First we generalize this method by adding dimension type free
parameters. Then we deal with the optimization problem of the free parameters.
To this order, based on the well-known particle swarm optimization (PSO)
algorithm, we develop the multi-dimensional hyperbolic PSO algorithm. It is
designed especially for the rational transforms in question. As a result, the
system along with its dimension is dynamically optimized during the process.
The main motivation was to increase the adaptivity while keeping the
computational complexity manageable. We note that the proposed method is of
general nature. As a case study the problem of electrocardiogram (ECG) signal
compression is discussed. By means of comparison tests performed on the
PhysioNet MIT-BIH Arrhythmia database we demonstrate that our method
outperforms other transformation techniques.
