Factors Affecting the Performance of Automated Speaker Verification in Alzheimer's Disease Clinical Trials
Detecting duplicate patient participation in clinical trials is a major challenge because repeated patients can undermine the credibility and accuracy of the trial's findings and result in significant health and financial risks.
Cost-effective Models for Detecting Depression from Speech
Our findings suggest that models trained on conventional acoustic features perform equally well or better than the ones trained on deep representation features at significantly lower computational cost, irrespective of other factors, e. g. content and length of speech, gender of the speaker and severity of the disorder.
Multi-modal deep learning system for depression and anxiety detection
We find that augmenting hand-crafted features with deep-learned features improves our overall classification F1 score comparing to a baseline of hand-crafted features alone from 0. 58 to 0. 63 for depression and from 0. 54 to 0. 57 for anxiety.

Comparing Acoustic-based Approaches for Alzheimer's Disease Detection
Robust strategies for Alzheimer's disease (AD) detection are important, given the high prevalence of AD.
Augmenting BERT Carefully with Underrepresented Linguistic Features
Fine-tuned Bidirectional Encoder Representations from Transformers (BERT)-based sequence classification models have proven to be effective for detecting Alzheimer's Disease (AD) from transcripts of human speech.
Fantastic Features and Where to Find Them: Detecting Cognitive Impairment with a Subsequence Classification Guided Approach
Despite the widely reported success of embedding-based machine learning methods on natural language processing tasks, the use of more easily interpreted engineered features remains common in fields such as cognitive impairment (CI) detection.
To BERT or Not To BERT: Comparing Speech and Language-based Approaches for Alzheimer's Disease Detection
Research related to automatically detecting Alzheimer's disease (AD) is important, given the high prevalence of AD and the high cost of traditional methods.
Cross-Language Aphasia Detection using Optimal Transport Domain Adaptation
We learn mappings from other languages to English and detect aphasia from linguistic characteristics of speech, and show that OT domain adaptation improves aphasia detection over unilingual baselines for French (6% increased F1) and Mandarin (5% increased F1).
Lexical Features Are More Vulnerable, Syntactic Features Have More Predictive Power
Understanding the vulnerability of linguistic features extracted from noisy text is important for both developing better health text classification models and for interpreting vulnerabilities of natural language models.

Evaluating the State-of-the-Art of End-to-End Natural Language Generation: The E2E NLG Challenge
Introducing novel automatic and human metrics, we compare 62 systems submitted by 17 institutions, covering a wide range of approaches, including machine learning architectures -- with the majority implementing sequence-to-sequence models (seq2seq) -- as well as systems based on grammatical rules and templates.
The Effect of Heterogeneous Data for Alzheimer's Disease Detection from Speech
We analyze the impact of age of the added samples and if they affect fairness in classification.

Data-driven Natural Language Generation: Paving the Road to Success
We argue that there are currently two major bottlenecks to the commercial use of statistical machine learning approaches for natural language generation (NLG): (a) The lack of reliable automatic evaluation metrics for NLG, and (b) The scarcity of high quality in-domain corpora.
