内容：

In this talk, I will first provide a brief overview of conformal prediction, covering its core algorithms and theoretical guarantees. As a prominent framework in uncertainty quantification, conformal prediction has gained attentions for its simplicity and theoretical foundations. We will begin by discussing the practical deployment of conformal prediction—addressing when and how to apply it in real-world scenarios. I will then delve into its theoretical guarantees, focusing specifically on the coverage properties of the confidence bands it produces. Moving beyond the foundational framework, I will introduce a series of works aimed at improving the precision and reliability of the confidence bands returned by conformal prediction. These include: (a) enhancing precision under neural network regimes; (b) modifying the confidence bands without changing the training process; (c) investigating the evaluation metrics regarding the reliability requirements; and (d) developing variants tailored to different data structures.
