Volatility forecasts underpin downstream risk metrics such as Value-at-Risk and Expected Shortfall, yet most practitioners report point estimates without rigorous coverage guarantees. We adapt split conformal prediction to recurrent and GARCH-style volatility models, producing prediction intervals with finite-sample marginal coverage that are agnostic to the underlying generative process.

Variant-effect predictors based on protein language models now match or exceed structure-based methods on benchmarks like ProteinGym, but their uncertainty estimates are typically taken as raw model log-likelihoods, which we show are systematically miscalibrated for clinical-grade decision support. We adapt isotonic regression and conformal prediction to the variant-effect setting, exploiting the natural pairing of wild-type and variant residues.

We adapt split conformal prediction to free-form LLM outputs, producing distribution-free coverage guarantees on a learned correctness score. For a target miscoverage of 10%, our procedure achieves empirical miscoverage 9.

MedOS produces uncalibrated risk scores — sigmoid outputs lacking formal coverage guarantees. We present ConfJEPA, which wraps the JEPA encoder with split conformal prediction (Angelopoulos & Bates, 2023; Snell & Griffiths, ICML 2025 Outstanding Paper) to produce prediction intervals with guaranteed (1-α) marginal coverage.

有机光伏（OPV）器件的性能根本上由供体与受体之间的界面电子耦合决定。本文提出OPVFormer，一个基于双向交叉注意力（BCA）与共形量化回归（CQR）的深度预测框架。BCA同时建模供体→受体与受体→供体的双向电荷转移，CQR在无需分布假设的前提下提供有限样本校准的预测区间。在OPVDB、Figshare等数据集上，PCE预测MAE达0.64%，95%置信水平覆盖率达95.
