Towards robust databases: an ensemble-based workflow for error detection applied to chemical data 1. This study introduces a validated and refined “yellow cards” error detection workflow for chemical data, which can be applied to any property connected to molecular structure. The workflow uses five predictive models to flag potentially erroneous entries with high precision. 2. The core innovation lies in the ensemble approach: each model assigns a “yellow card” to the 5% of entries with the worst prediction accuracy. Entries receiving five “yellow cards” are considered erroneous. This method effectively leverages model diversity to enhance error detection. 3. The study confirms five key hypotheses: models generalize well and ignore errors during training; prediction errors across different model architectures are weakly correlated; the group with the most “yellow cards” is dominated by erroneous entries; the U-shaped distribution of entries across groups and inverted-U pattern in standard deviations serve as robust indicators of workflow performance. 4. The “yellow cards” workflow outperforms simpler methods like absolute error or percentile-based approaches in precision-recall metrics. This makes it a superior choice for identifying and filtering out errors in large chemical datasets. 5. The researchers provide a detailed, actionable plan for applying this method to new datasets, emphasizing model diversity, hyperparameter optimization, threshold selection, and iterative refinement using diagnostic plots. This plan is designed to be adaptable to various molecular properties. 6. The study uses two computational datasets (descriptor-based and QM9-based) with controlled errors to rigorously test and validate the workflow. This approach allows for a thorough assessment of the method’s performance and versatility. 7. The findings have broad implications for improving data quality in chemistry and molecular sciences, potentially enhancing the reliability of machine learning models trained on such data. This work paves the way for more robust and reliable data curation practices. 📜Paper: doi.org/10.26434/chemrxiv-20… #ChemistryData #ErrorDetection #MachineLearning #DataQuality #EnsembleMethods

8/25 Uncertainty Quantification for Clinical Outcome Predictions with (Large) Language Models This paper investigates uncertainty quantification of Language Models (LMs) for clinical prediction tasks using EHRs, addressing the need for reliable automated predictions in healthcare. Using multi-tasking and ensemble methods in both white-box (accessible parameters and logits) and black-box (e.g., GPT-4) settings, they demonstrate uncertainty reduction on longitudinal clinical data from over 6,000 patients across ten clinical prediction tasks. Results show that ensembling and multi-task prompting reduce uncertainty, improving transparency and reliability in AI healthcare. #UncertaintyQuantification #LanguageModels #EHR #ClinicalPrediction #AIHealthcare #EnsembleMethods #MultiTaskLearning Paper Link: arxiv.org/abs/2411.03497
