In academic parlance, “artifact” can refer to a physical object, a primary record, or a physical object that constitutes a primary record. a library or archival resource that has value as a physical object in addition to its informational value (View Citations) Nichols and Smith 2001, 8The word “artifact” can be confusing because it masks a number of unexamined assumptions.

For longer gaps, cubic interpolation can in some cases result in lower error in HRV measures, but the shape of the curve it generates matches ground truth worse than our algorithm. At the same time, the error introduced to HRV measures for peak correction and shorter gaps is similar to the best existing solution (Kubios-inspired threshold-based cubic interpolation) and better than commonly used median filter.
PHYSICAL ARTIFACT MEANING MANUAL
Early results suggest that the algorithm can correct more artifacts than existing solutions without a need for manual support or parameter tuning.

Data include direct measurement of electrical myocardial signals using chest straps and direct measurements of power using a crank sensor (in case of race dataset), both paired with the watch. One collected during a recreational bicycle race and another one in a laboratory, both using a PMD in form of a GPS watch. We verify this algorithm based on two datasets.

To address this issue we propose an algorithm for automated artifact correction that has a minimal impact on HRV measures, but can handle more artifacts than existing solutions. However, current artifact correction approaches have several limitations that hamper the analysis of real-life HRV data. With proliferation of Personal Monitoring Devices with continuous HRV analysis an opportunity opens for HRV analysis in a new setting. Since many of the typical HRV measures are sensitive to data quality, manual artifact correction is common in literature, both as an exclusive method or in addition to various filters. Currently, such analysis is usually performed in controlled or semi-controlled conditions. Heart rate variability (HRV) analysis can be a useful tool to detect underlying heart or even general health problems.
