smile.datasets.SyntheticControl
Record Components:
data - data frame.
public record SyntheticControl(DataFrame data) extends Record
Synthetic control time series. This dataset contains 600 examples of control charts synthetically generated by the process in the paper Time-Series Similarity Queries Employing a Feature-Based Approach. There are six different classes of control charts: 1. Normal 2. Cyclic 3. Increasing trend 4. Decreasing trend 5. Upward shift 6. Downward shift
