SitterConformal

SitterConformal is a proposed method in statistical inference that aims to provide reliable prediction intervals for machine learning models. Traditional conformal prediction methods often rely on assumptions about the data distribution that may not hold in practice. SitterConformal seeks to address these limitations by introducing a "sitter" element, which acts as a reference point or baseline for comparison. This sitter helps to anchor the prediction intervals and make them more robust to distributional shifts or violations of standard assumptions.

The core idea behind SitterConformal is to construct prediction intervals that are valid for any new data point, regardless of its underlying distribution, as long as it comes from the same distribution as the training data. This is achieved by defining a non-conformity measure that quantifies how "unusual" a new data point is compared to the observed training data, considering the sitter's influence. The intervals are then calibrated based on these non-conformity scores.

While still a developing area, SitterConformal offers a promising direction for improving the reliability and trustworthiness of machine learning predictions. Its ability to provide guarantees on prediction intervals without strong distributional assumptions makes it attractive for applications where uncertainty quantification is critical, such as in healthcare, finance, and scientific research. Further research is ongoing to explore its theoretical properties and practical performance across various machine learning tasks.
