Temporal Supervised Contrastive Learning for Modeling Patient Risk Progression

1 code implementation10 Dec 2023 Shahriar Noroozizadeh, Jeremy C. Weiss, George H. Chen

To solve this problem, we propose a supervised contrastive learning framework that learns an embedding representation for each time step of a patient time series.

Fair Decision-making Under Uncertainty

no code implementations29 Jan 2023 Wenbin Zhang, Jeremy C. Weiss

There has been concern within the artificial intelligence (AI) community and the broader society regarding the potential lack of fairness of AI-based decision-making systems.

Longitudinal Fairness with Censorship

no code implementations30 Mar 2022 Wenbin Zhang, Jeremy C. Weiss

Recent works in artificial intelligence fairness attempt to mitigate discrimination by proposing constrained optimization programs that achieve parity for some fairness statistic.

Fairness Amidst Non-IID Graph Data: Current Achievements and Future Directions

no code implementations15 Feb 2022 Wenbin Zhang, SHimei Pan, Shuigeng Zhou, Toby Walsh, Jeremy C. Weiss

The importance of understanding and correcting algorithmic bias in machine learning (ML) has led to an increase in research on fairness in ML, which typically assumes that the underlying data is independent and identically distributed (IID).

FARF: A Fair and Adaptive Random Forests Classifier

no code implementations17 Aug 2021 Wenbin Zhang, Albert Bifet, Xiangliang Zhang, Jeremy C. Weiss, Wolfgang Nejdl

This algorithm, called FARF (Fair and Adaptive Random Forests), is based on using online component classifiers and updating them according to the current distribution, that also accounts for fairness and a single hyperparameters that alters fairness-accuracy balance.

Neural Topic Models with Survival Supervision: Jointly Predicting Time-to-Event Outcomes and Learning How Clinical Features Relate

no code implementations15 Jul 2020 Linhong Li, Ren Zuo, Amanda Coston, Jeremy C. Weiss, George H. Chen

As an alternative, we present an interpretable neural network approach to jointly learn a survival model to predict time-to-event outcomes while simultaneously learning how features relate in terms of a topic model.

Predicting Mortality Risk in Viral and Unspecified Pneumonia to Assist Clinicians with COVID-19 ECMO Planning

1 code implementation2 Jun 2020 Helen Zhou, Cheng Cheng, Zachary C. Lipton, George H. Chen, Jeremy C. Weiss

Finally, the PEER score is provided in the form of a nomogram for direct calculation of patient risk, and can be used to highlight at-risk patients among critical care patients eligible for ECMO.

Harmonic Mean Point Processes: Proportional Rate Error Minimization for Obtundation Prediction

no code implementations12 Nov 2019 Yoonjung Kim, Jeremy C. Weiss

We focus on this problem in point processes, a popular modeling technique for the analysis of the temporal event sequences in electronic health records (EHR) data with applications in risk stratification and risk score systems.

Clinical Risk: wavelet reconstruction networks for marked point processes

no code implementations27 Sep 2018 Jeremy C. Weiss

Timestamped sequences of events, pervasive in domains with data logs, e. g., health records, are often modeled as point processes with rate functions over time.

Survival-Supervised Topic Modeling with Anchor Words: Characterizing Pancreatitis Outcomes

no code implementations2 Dec 2017 George H. Chen, Jeremy C. Weiss

For example, by seeing "gallstones" in a document, we are fairly certain that the document is partially about medicine.
