Module control of network analysis in psychopathology [PDF]

open access: yesarXiv
The network approach to characterizing psychopathology departs from traditional latent categorical and dimensional approaches. Causal interplay among symptoms contributed to dynamic psychopathology system. Therefore, analyzing the symptom clusters is critical for understanding mental disorders.

AR(1) Latent Class Models for Longitudinal Count Data [PDF]

open access: yesarXiv, 2015
In a variety of applications involving longitudinal or repeated-measurements data, it is desired to uncover natural groupings or clusters which exist among study subjects. Motivated by the need to recover longitudinal trajectories of conduct problems in the field of developmental psychopathology, we propose a method to address this goal when the data ...

Measuring Mental Health Variables in Computational Research: Toward Validated, Dimensional, and Transdiagnostic Approaches [PDF]

open access: yesarXiv
Computational mental health research develops models to predict and understand psychological phenomena, but often relies on inappropriate measures of psychopathology constructs, undermining validity. We identify three key issues: (1) reliance on unvalidated measures (e.g., self-declared diagnosis) over validated ones (e.g., diagnosis by clinician); (2)

The Importance of Constraint Smoothness for Parameter Estimation in Computational Cognitive Modeling [PDF]

open access: yesarXiv, 2018
Psychiatric neuroscience is increasingly aware of the need to define psychopathology in terms of abnormal neural computation. The central tool in this endeavour is the fitting of computational models to behavioural data. The most prominent example of this procedure is fitting reinforcement learning (RL) models to decision-making data collected from ...

Emergence of Addictive Behaviors in Reinforcement Learning Agents [PDF]

open access: yesarXiv, 2018
This paper presents a novel approach to the technical analysis of wireheading in intelligent agents. Inspired by the natural analogues of wireheading and their prevalent manifestations, we propose the modeling of such phenomenon in Reinforcement Learning (RL) agents as psychological disorders.

Intervention in undirected Ising graphs and the partition function [PDF]

open access: yesarXiv, 2019
Undirected graphical models have many applications in such areas as machine learning, image processing, and, recently, psychology. Psychopathology in particular has received a lot of attention, where symptoms of disorders are assumed to influence each other.

Predictors and (in-)stability of ICD-11 complex posttraumatic stress disorder in older adults: findings from a longitudinal study in Switzerland

open access: yesEuropean Journal of Psychotraumatology
Objective: There is a lack of research on complex post-traumatic stress disorder (CPTSD) in older individuals, with little known about the temporal course of CPTSD.
