title = "A recovery of FHR signal in the embedded space",
abstract = "In the paper we present a proposition of a recovery method for fetal heart rate signals (FHR). Recorded FHR signal often contains interruptions. The interruptions of the signal are caused among others by fetal movements. In such cases, the instantaneous heart rate determination is difficult because parts of the signal are missing. For the reconstruction of missing parts of the FHR signal, an approximation in an embedded space is proposed. The embedded space is created by applying the Taken's theory. Next, the vicinity is determined for the missing samples (missing features in the embedded space). For the vicinity computation, two strategies are chosen: the nearest surrounding of the approximated sample or K nearest neighborhoods. The missing value is computed as a mean or a median. Numerical experiments performed for test (simulated) signals and the real FHR signal show advantages of proposed approach.",
