Zero-Shot Clinical Acronym Expansion via Latent Meaning Cells

1 code implementation29 Sep 2020 Griffin Adams, Mert Ketenci, Shreyas Bhave, Adler Perotte, Noémie Elhadad

We introduce Latent Meaning Cells, a deep latent variable model which learns contextualized representations of words by combining local lexical context and metadata.

A Coreset-based, Tempered Variational Posterior for Accurate and Scalable Stochastic Gaussian Process Inference

no code implementations2 Nov 2023 Mert Ketenci, Adler Perotte, Noémie Elhadad, Iñigo Urteaga

We present a novel stochastic variational Gaussian process ($\mathcal{GP}$) inference method, based on a posterior over a learnable set of weighted pseudo input-output points (coresets).

Maximum Likelihood Estimation of Flexible Survival Densities with Importance Sampling

no code implementations3 Nov 2023 Mert Ketenci, Shreyas Bhave, Noémie Elhadad, Adler Perotte

We propose a survival analysis approach which eliminates the need to tune hyperparameters such as mixture assignments and bin sizes, reducing the burden on practitioners.
