Fetal_cardiotocography_dataset

2126 fetal cardiotocograms (CTGs) were automatically processed and the respective diagnostic features measured. The CTGs were also classified by three expert obstetricians and a consensus classification label assigned to each of them. Classification was both with respect to a morphologic pattern (A, B, C. ...) and to a fetal state (N, S, P). Therefore the dataset can be used either for 10-class or 3-class experiments. FileName: of CTG examination Date: of the examination b: start instant e: end instant LBE: baseline value (medical expert) LB: baseline value (SisPorto) AC: accelerations (SisPorto) FM: foetal movement (SisPorto) UC: uterine contractions (SisPorto) ASTV: percentage of time with abnormal short term variability (SisPorto) mSTV: mean value of short term variability (SisPorto) ALTV: percentage of time with abnormal long term variability (SisPorto) mLTV: mean value of long term variability (SisPorto) DL: light decelerations DS: severe decelerations DP: prolongued decelerations DR: repetitive decelerations Width: histogram width Min: low freq. of the histogram Max: high freq. of the histogram Nmax: number of histogram peaks Nzeros: number of histogram zeros Mode: histogram mode Mean: histogram mean Median: histogram median Variance: histogram variance Tendency: histogram tendency: -1=left assymetric; 0=symmetric; 1=right assymetric A: calm sleep B: REM sleep C: calm vigilance D: active vigilance SH: shift pattern (A or Susp with shifts) AD: accelerative/decelerative pattern (stress situation) DE: decelerative pattern (vagal stimulation) LD: largely decelerative pattern FS: flat-sinusoidal pattern (pathological state) SUSP: suspect pattern CLASS: Class code (1 to 10) for classes A to SUSP NSP:- Normal=1; Suspect=2; Pathologic=3 We drop all nan values from the CLASS column dataset to avoid problems when uploading the dataset to OpenML. We drop the columns FileName, SegFile and Date, as they are not relevant for the analysis.
