Neural Fine-Gray: Monotonic neural networks for competing risks

1 code implementation11 May 2023 Vincent Jeanselme, Chang Ho Yoon, Brian Tom, Jessica Barrett

Time-to-event modelling, known as survival analysis, differs from standard regression as it addresses censoring in patients who do not experience the event of interest.

Imputation Strategies Under Clinical Presence: Impact on Algorithmic Fairness

1 code implementation13 Aug 2022 Vincent Jeanselme, Maria De-Arteaga, Zhe Zhang, Jessica Barrett, Brian Tom

Machine learning risks reinforcing biases present in data, and, as we argue in this work, in what is absent from data.

DeepJoint: Robust Survival Modelling Under Clinical Presence Shift

1 code implementation26 May 2022 Vincent Jeanselme, Glen Martin, Niels Peek, Matthew Sperrin, Brian Tom, Jessica Barrett

Observational data in medicine arise as a result of the complex interaction between patients and the healthcare system.

Constrained Clustering and Multiple Kernel Learning without Pairwise Constraint Relaxation

1 code implementation23 Mar 2022 Benedikt Boecking, Vincent Jeanselme, Artur Dubrawski

However, the common practice of relaxing discrete constraints to a continuous domain to ease optimization when learning kernels or metrics can harm generalization, as information which only encodes linkage is transformed to informing distances.

Constrained Clustering

Leveraging Expert Consistency to Improve Algorithmic Decision Support

no code implementations24 Jan 2021 Maria De-Arteaga, Vincent Jeanselme, Artur Dubrawski, Alexandra Chouldechova

However, there is frequently a gap between decision objectives and what is captured in the observed outcomes used as labels to train ML models.
