Sequential Inference of Hospitalization Electronic Health Records Using Probabilistic Models

no code implementations27 Mar 2024 Alan D. Kaplan, Priyadip Ray, John D. Greene, Vincent X. Liu

Inference algorithms are derived that use partial data to infer properties of the complete sequences, including their length and presence of specific values.

Tangent functional connectomes uncover more unique phenotypic traits

no code implementations13 Dec 2022 Kausar Abbas, Mintao Liu, Michael Wang, Duy Duong-Tran, Uttara Tipnis, Enrico Amico, Alan D. Kaplan, Mario Dzemidzic, David Kareken, Beau M. Ances, Jaroslaw Harezlak, Joaquín Goñi

(ii) In tangent-FCs, Main-diagonal regularization prior to tangent space projection was critical for ID rate when using Euclidean distance, whereas barely affected ID rates when using correlation distance.

Unsupervised Probabilistic Models for Sequential Electronic Health Records

no code implementations15 Apr 2022 Alan D. Kaplan, John D. Greene, Vincent X. Liu, Priyadip Ray

We develop an unsupervised probabilistic model for heterogeneous Electronic Health Record (EHR) data.

Mixture Model Framework for Traumatic Brain Injury Prognosis Using Heterogeneous Clinical and Outcome Data

no code implementations22 Dec 2020 Alan D. Kaplan, Qi Cheng, K. Aditya Mohan, Lindsay D. Nelson, Sonia Jain, Harvey Levin, Abel Torres-Espin, Austin Chou, J. Russell Huie, Adam R. Ferguson, Michael McCrea, Joseph Giacino, Shivshankar Sundaram, Amy J. Markowitz, Geoffrey T. Manley

Using a data-driven approach on many distinct data elements may be necessary to describe this large set of outcomes and thereby robustly depict the nuanced differences among TBI patients' recovery.

Functional Connectome Fingerprint Gradients in Young Adults

no code implementations10 Nov 2020 Uttara Tipnis, Kausar Abbas, Elizabeth Tran, Enrico Amico, Li Shen, Alan D. Kaplan, Joaquín Goñi

Our differential identifiability results show that the fingerprint gradients based on genetic and environmental similarities are indeed present when comparing FCs for all parcellations and fMRI conditions.

AutoAtlas: Neural Network for 3D Unsupervised Partitioning and Representation Learning

1 code implementation29 Oct 2020 K. Aditya Mohan, Alan D. Kaplan

AutoAtlas consists of two neural network components: one neural network to perform multi-label partitioning based on local texture in the volume, and a second neural network to compress the information contained within each partition.

Feature Importance Representation Learning

Attend and Decode: 4D fMRI Task State Decoding Using Attention Models

1 code implementation10 Apr 2020 Sam Nguyen, Brenda Ng, Alan D. Kaplan, Priyadip Ray

We also investigate the transferability of BAnD's extracted features on unseen HCP tasks, either by freezing the spatial feature extraction layers and retraining the temporal model, or finetuning the entire model.
