Benchmarking changepoint detection algorithms on cardiac time series

no code implementations16 Apr 2024 Ayse Cakmak, Erik Reinertsen, Shamim Nemati, Gari D. Clifford

This work represents the first time change point detection algorithms have been compared in a meaningful way and utilized in a classification task, which demonstrates the effect of changepoint algorithm choice on application performance.

Reinforcement Learning in Healthcare: A Survey

no code implementations22 Aug 2019 Chao Yu, Jiming Liu, Shamim Nemati

As a subfield of machine learning, reinforcement learning (RL) aims at empowering one's capabilities in behavioural decision making by using interaction experience with the world and an evaluative feedback.

DeepAISE -- An End-to-End Development and Deployment of a Recurrent Neural Survival Model for Early Prediction of Sepsis

no code implementations10 Aug 2019 Supreeth P. Shashikumar, Christopher Josef, ASHISH SHARMA, Shamim Nemati

Sepsis, a dysregulated immune system response to infection, is among the leading causes of morbidity, mortality, and cost overruns in the Intensive Care Unit (ICU).

Specificity Time Series Analysis

Does the "Artificial Intelligence Clinician" learn optimal treatment strategies for sepsis in intensive care?

1 code implementation8 Feb 2019 Russell Jeter, Christopher Josef, Supreeth Shashikumar, Shamim Nemati

The results of studies involving machine learning, artificial intelligence (AI), and big data have captured the attention of healthcare practitioners, healthcare managers, and the public at a time when Western medicine grapples with unmitigated cost increases and public demands for accountability.

Addressing Class Imbalance in Classification Problems of Noisy Signals by using Fourier Transform Surrogates

no code implementations20 Jun 2018 Justus T. C. Schwabedal, John C. Snyder, Ayse Cakmak, Shamim Nemati, Gari. D. Clifford

To quantify how well the distributions of the surrogates and the original data match, we evaluated a trained classifier on surrogates of correctly classified examples, and summarized these conditional predictions in a confusion matrix.

Detection of Paroxysmal Atrial Fibrillation using Attention-based Bidirectional Recurrent Neural Networks

1 code implementation7 May 2018 Supreeth P. Shashikumar, Amit J. Shah, Gari. D. Clifford, Shamim Nemati

We also demonstrate the cross-domain generalizablity of the approach by adapting the learned model parameters from one recording modality (ECG) to another (photoplethysmogram) with improved AF detection performance.

Patient Flow Prediction via Discriminative Learning of Mutually-Correcting Processes

no code implementations14 Feb 2016 Hongteng Xu, Weichang Wu, Shamim Nemati, Hongyuan Zha

By treating a sequence of transition events as a point process, we develop a novel framework for modeling patient flow through various CUs and jointly predicting patients' destination CUs and duration days.
