Installation

The codes were written in Python 3.9.13. If you want to implement locally,

1. Clone this repository

2. Move to the directory where you clone this repository and install requirements using pip

    pip install -r requirements.txt
   

Experiments using Colab Notebook

We also provide colab notebook for reproducing the results. Note that results from colab notebook shows slightly different performance from the results in the paper.

Simulation: time series with heteroscedastic errors

Conformal prediction on time series with heteroscedastic errors as described in Section 4.2 in the paper.

Real Data Experiment: Electricity dataset

Conformal prediction on the electricity dataset in Section 4.3 in the paper.
