• Title: Analyzing the Effect of Data Impurity on the Detection Performances of Mental Disorders
• Authors: Rohan Kumar Gupta and Rohit Sinha
• Abstract summary: It is widely recognized that certain mental disorders share similar symptoms, causing the collected behavioral data to encompass a variety of attributes associated with multiple disorders. In this study, we investigate this hypothesis in the context of major depressive disorder (MDD) and post-traumatic stress disorder detection (PTSD) The results show that upon removal of such data impurity, MDD and PTSD detection performances are significantly improved.

• Abstract: The primary method for identifying mental disorders automatically has traditionally involved using binary classifiers. These classifiers are trained using behavioral data obtained from an interview setup. In this training process, data from individuals with the specific disorder under consideration are categorized as the positive class, while data from all other participants constitute the negative class. In practice, it is widely recognized that certain mental disorders share similar symptoms, causing the collected behavioral data to encompass a variety of attributes associated with multiple disorders. Consequently, attributes linked to the targeted mental disorder might also be present within the negative class. This data impurity may lead to sub-optimal training of the classifier for a mental disorder of interest. In this study, we investigate this hypothesis in the context of major depressive disorder (MDD) and post-traumatic stress disorder detection (PTSD). The results show that upon removal of such data impurity, MDD and PTSD detection performances are significantly improved.

  Self-supervised learning (SSL) has been investigated to generate task-agnostic representations across various domains. This study employs SSL models trained by predicting multiple fixed targets or masked frames. We propose a list of fixed targets to make the generated representation more efficient for detecting MDD and PTSD.

  Major depressive disorder (MDD) is a complex psychiatric disorder that affects hundreds of millions of individuals around the globe. The application of deep learning tools to neuroimaging data has the potential to provide diagnostic and predictive biomarkers for MDD. Previous attempts to demarcate MDD patients and healthy controls (HC) based on segmented cortical features via linear machine learning approaches have reported low accuracies.

  We propose to improve the recognition performance by making use of the observation that patients tend to show specific behaviors at certain times of the day or week. All time segments within a cluster then consist of similar behaviors and thus indicate a behavioral predisposition (BPD) Empirically, we demonstrate that when the BPD per time segment is known, activity recognition performance can be substantially improved.
