Assessing Depression and Anxiety in Elderly Brazilians: Transferability of AI Models Trained on a Non-Verbal Working Memory Task

The current study aims to illustrate the preliminary transferability of two established AI models designed for detecting depression and anxiety.

The models were initially trained on data from a non-verbal working memory game (1- and 2-back) in the thymia dataset, encompassing over 6,000 participants from the United Kingdom, United States, Mexico, Spain, and Indonesia

This study successfully demonstrates the preliminary transferability of two AI models trained on a non-verbal working memory task, one for depression and the other for anxiety classification, to a novel demographic of elderly Brazilian adults.

Path Signature Representation of Patient-Clinician Interactions as a Predictor for Neuropsychological Tests Outcomes in Children

This research report presents a proof-of-concept study on the application of machine learning techniques to video and speech data collected during diagnostic cognitive assessments of children with a neurodevelopmental disorder.

The study utilised a dataset of 39 video recordings, capturing extensive sessions where clinicians administered, among other things, four cognitive assessment tests. From the first 40 minutes of each clinical session, covering the administration of the Wechsler Intelligence Scale for Children (WISC-5), we extracted head positions and speech turns of both clinician and child.

Bayesian Networks for the robust and unbiased prediction of depression and its symptoms utilizing speech and multimodal data

Our paper got accepted into interspeech 2023!

In this study, we apply a Bayesian framework to capture the relationships between depression, depression symptoms, and features derived from speech, facial expression and cognitive game data collected at thymia.

Speech and the n-Back task as a lens into depression

Our paper got accepted into interspeech 2022!

This paper presents strong evidence that embedded in any speech signal is a rich combination of cognitive, neuromuscular and physiological information. This richness makes speech a powerful signal in relation to a range of different health conditions, including major depressive disorders (MDD).

We then present a set of machine learning experiments that demonstrate that combining speech with features from an n-Back working memory assessment improves classifier performance when predicting the popular eight-item Patient Health Questionnaire depression scale (PHQ-8).
