This document discusses using machine learning to analyze individual and interpersonal behavior for clinical diagnosis and screening. It focuses on analyzing non-verbal behaviors like interpersonal synchronization that have been shown to be impaired in conditions like autism spectrum disorder. The document proposes that machine learning could provide an objective, automated tool for diagnosing conditions more quickly by analyzing video recordings of social interactions. This may help address bottlenecks in healthcare systems and allow earlier access to treatment.

Screening and diagnosis
• Early screening is crucial
• Urgent need for a faster and objective automatized diagnostic tool
• Alleviate bottlenecks in the healthcare system
• Earlier access to benefits, specific interventions and other healthcare
programs
• A relief in the demand of health care resources associated with mental
health comorbidities in ASD

Screening and diagnosis
• ML for the analysis of individual and interpersonal non-verbal
behaviour in clinical patients
• Interpersonal behavior is associated with other conditions:
• Schizophrenia (Varlet et al., 2012, Kupper et al., 2015)
• Social anxiety disorder (Varlet et al., 2014)
• Borderline personality disorder (Gratier)

Take away
• ML can save years (decades?) of work to domain experts:
the algorithms discover the patterns for them.
• Deployment in far less-constrained environments.
• Same methods can be reused in various applications. Saves time and
costs!
