Reexamining Racial Disparities in Automatic Speech Recognition Performance: The Role of Confounding by Provenance

no code implementations19 Jul 2024 Changye Li, Trevor Cohen, Serguei Pakhomov

Automatic speech recognition (ASR) models trained on large amounts of audio data are now widely used to convert speech to written text in a variety of applications from video captioning to automated assistants used in healthcare and other domains.

Language Models Resist Alignment

1 code implementation10 Jun 2024 Jiaming Ji, Kaile Wang, Tianyi Qiu, Boyuan Chen, Jiayi Zhou, Changye Li, Hantao Lou, Yaodong Yang

Empirically, we demonstrate the elasticity of post-alignment models, i. e., the tendency to revert to the behavior distribution formed during the pre-training phase upon further fine-tuning.

Too Big to Fail: Larger Language Models are Disproportionately Resilient to Induction of Dementia-Related Linguistic Anomalies

1 code implementation5 Jun 2024 Changye Li, Zhecheng Sheng, Trevor Cohen, Serguei Pakhomov

As artificial neural networks grow in complexity, understanding their inner workings becomes increasingly challenging, which is particularly important in healthcare applications.

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).
