Multimodal hierarchical multi-task deep learning framework for jointly predicting and explaining Alzheimer disease progression

no code implementations4 Apr 2024 Sayantan Kumar, Sean Yu, Thomas Kannampallil, Andrew Michelson, Aristeidis Sotiras, Philip Payne

We proposed a multimodal hierarchical multi-task learning approach which can monitor the risk of disease progression at each timepoint of the visit trajectory.

Prescribing Large Language Models for Perioperative Care: What's The Right Dose for Pre-trained Models?

1 code implementation27 Feb 2024 Bing Xue, Charles Alba, Joanna Abraham, Thomas Kannampallil, Chenyang Lu

Adapting models further improved performance: (1) self-supervised finetuning by 3. 2% for AUROC and 1. 5% for AUPRC; (2) semi-supervised finetuning by 1. 8% for AUROC and 2% for AUPRC, compared to self-supervised finetuning; (3) foundational modelling by 3. 6% for AUROC and 2. 6% for AUPRC, compared to self-supervised finetuning.

Utilizing Semantic Textual Similarity for Clinical Survey Data Feature Selection

1 code implementation19 Aug 2023 Benjamin C. Warner, Ziqi Xu, Simon Haroutounian, Thomas Kannampallil, Chenyang Lu

A relatively unexplored source of information in the feature selection process is the usage of textual names of features, which may be semantically indicative of which features are relevant to a target outcome.

Self-explaining Neural Network with Concept-based Explanations for ICU Mortality Prediction

no code implementations9 Oct 2021 Sayantan Kumar, Sean C. Yu, Thomas Kannampallil, Zachary Abrams, Andrew Michelson, Philip R. O. Payne

Complex deep learning models show high prediction tasks in various clinical prediction tasks but their inherent complexity makes it more challenging to explain model predictions for clinicians and healthcare providers.

Predicting Intraoperative Hypoxemia with Hybrid Inference Sequence Autoencoder Networks

no code implementations30 Apr 2021 Hanyang Liu, Michael C. Montana, Dingwen Li, Chase Renfroe, Thomas Kannampallil, Chenyang Lu

We present an end-to-end model using streaming physiological time series to predict near-term risk for hypoxemia, a rare, but life-threatening condition known to cause serious patient harm during surgery.
