Comment on the Positive Predictive Value [PDF]

open access: yesDeutsches Ärzteblatt international, 2011
I enjoyed reading this informative and well structured article. Everyone involved in neonatal screening—in hospital and clinical practice and in the laboratory—would be well advised to have this review article and its practical tables ready to hand. I do not think, however, that the positive predictive value reported by the authors on page 16 for ...

Transformer-based Time-to-Event Prediction for Chronic Kidney Disease Deterioration [PDF]

open access: yes, 2023
Deep-learning techniques, particularly the transformer model, have shown great potential in enhancing the prediction performance of longitudinal health records. While previous methods have mainly focused on fixed-time risk prediction, time-to-event prediction (also known as survival analysis) is often more appropriate for clinical scenarios.

The validity of the claims-based definition of rheumatoid arthritis evaluated in 64 hospitals in Japan

open access: yesBMC Musculoskeletal Disorders, 2021
Background An administrative database covering a whole population such as the national database in Japan may be used to estimate the nationwide prevalence of diseases including rheumatoid arthritis (RA) when a well-validated definition of the disease is ...

Rethinking Position Bias Modeling with Knowledge Distillation for CTR Prediction [PDF]

open access: yesarXiv, 2022
Click-through rate (CTR) Prediction is of great importance in real-world online ads systems. One challenge for the CTR prediction task is to capture the real interest of users from their clicked items, which is inherently biased by presented positions of items, i.e., more front positions tend to obtain higher CTR values.

JPAVE: A Generation and Classification-based Model for Joint Product Attribute Prediction and Value Extraction [PDF]

open access: yesarXiv, 2023
Product attribute value extraction is an important task in e-Commerce which can help several downstream applications such as product search and recommendation. Most previous models handle this task using sequence labeling or question answering method which rely on the sequential position information of values in the product text and are vulnerable to ...

Identifying incident cancer cases in dispensing claims

open access: yesInternational Journal of Population Data Science, 2020
Introduction Dispensing claims are used commonly as proxy measures in pharmacoepidemiological studies; however, their validity is often untested. Objectives To assess the performance of a proxy for identifying cancer cases based on the dispensing of ...

Positive Feature Values Prioritized Hierarchical Redundancy Eliminated Tree Augmented Naive Bayes Classifier for Hierarchical Feature Spaces [PDF]

open access: yesarXiv, 2022
The Hierarchical Redundancy Eliminated Tree Augmented Naive Bayes (HRE-TAN) classifier is a semi-naive Bayesian model that learns a type of hierarchical redundancy-free tree-like feature representation to estimate the data distribution. In this work, we propose two new types of positive feature values prioritized hierarchical redundancy eliminated tree

Positive and negative predictive values by the TOC curve

open access: yesCommunications for Statistical Applications and Methods, 2020
Sensitivity and specificity are popular measures described by the receiver operating characteristic (ROC) curve. There are also two other measures such as the positive predictive value (PPV) and negative predictive value (NPV); however, the PPV and NPV cannot be represented by the ROC curve.
