Official implementation of the work Sequential Predictive Conformal Inference for Time Series (ICML 2023).
Please direct questions regarding implementation to cxu310@gatech.edu.
See tutorial_electric_EnbPI_SPCI.ipynb for comparing SPCI against EnbPI, which is an earlier method of ours. We demonstrate significant reduction in interval width on the electric dataset, which is also used in Nex-CP (Barber et al., 2022).
