Everyday Living Artificial Intelligence Hub

no code implementations NAACL (DaSH) 2021 Raymond Finzel, Esha Singh, Martin Michalowski, Maria Gini, Serguei Pakhomov

We present the Everyday Living Artificial Intelligence (AI) Hub, a novel proof-of-concept framework for enhancing human health and wellbeing via a combination of tailored wear-able and Conversational Agent (CA) solutions for non-invasive monitoring of physiological signals, assessment of behaviors through unobtrusive wearable devices, and the provision of personalized interventions to reduce stress and anxiety.

Useful Blunders: Can Automated Speech Recognition Errors Improve Downstream Dementia Classification?

no code implementations10 Jan 2024 Changye Li, Weizhe Xu, Trevor Cohen, Serguei Pakhomov

\textbf{Results}: Imperfect ASR-generated transcripts surprisingly outperformed manual transcription for distinguishing between individuals with AD and those without in the ``Cookie Theft'' task.

TRESTLE: Toolkit for Reproducible Execution of Speech, Text and Language Experiments

1 code implementation14 Feb 2023 Changye Li, Weizhe Xu, Trevor Cohen, Martin Michalowski, Serguei Pakhomov

The evidence is growing that machine and deep learning methods can learn the subtle differences between the language produced by people with various forms of cognitive impairment such as dementia and cognitively healthy individuals.

The Far Side of Failure: Investigating the Impact of Speech Recognition Errors on Subsequent Dementia Classification

1 code implementation11 Nov 2022 Changye Li, Trevor Cohen, Serguei Pakhomov

Linguistic anomalies detectable in spontaneous speech have shown promise for various clinical applications including screening for dementia and other forms of cognitive impairment.

GPT-D: Inducing Dementia-related Linguistic Anomalies by Deliberate Degradation of Artificial Neural Language Models

2 code implementations ACL 2022 Changye Li, David Knopman, Weizhe Xu, Trevor Cohen, Serguei Pakhomov

Deep learning (DL) techniques involving fine-tuning large numbers of model parameters have delivered impressive performance on the task of discriminating between language produced by cognitively healthy individuals, and those with Alzheimer's disease (AD).

A Conversational Agent System for Dietary Supplements Use

no code implementations4 Apr 2021 Esha Singh, Anu Bompelli, Ruyuan Wan, Jiang Bian, Serguei Pakhomov, Rui Zhang

Dietary supplements (DS) have been widely used by consumers, but the information around the efficacy and safety of DS is disparate or incomplete, thus creating barriers for consumers to find information effectively.
