About this file:
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.
