This package implements both computationally and statistically efficient solutions to compute the “exact full conformal prediction set (full-CP)” of a Sparse High-order Interaction Model (SHIM). To the best of our knowledge, this is the first attempt to compute an exact full-CP of a complex model such as a SHIM. This is also the first attempt to construct a conformal prediction set in the context of a pattern mining model which is fitted with a branch and bound approach. As of today, an efficient exact full-CP is possible only for simple regression models such as LASSO, ridge regression, and ordinary least square regression. The proposed method adds SHIM to that list.
See our paper https://arxiv.org/pdf/2205.14317.pdf for more details.
This package has the following requirements:
We recommend installing or updating anaconda to the latest version and use Python 3 (We used Python 3.9.7).
All commands are run from the terminal.
NOTE: Due to the randomness of data generating process, we note that the results might be slightly different from the paper. However, the overall results for interpretation will not change.
All the figure results are saved in folder "/results"
