Identifying IIR filter coefficients using particle swarm optimization with application to reconstruction of missing cardiovascular signals
We introduce a methodology to reconstruct missing segments of multidimensional data. IIR transfer function coefficients are identified using particle swarm optimization. The method was successfully applied to intensive care unit (ICU) dataset. Advantages are simplicity, fast computation and good results on available datasets. The method is trivial to parallelize and it would be straight forward to apply online.
