In recent years, there has been an increase in interest and explorations of the use of machine learning (ML) to assist in the diagnosis of mental health problems; and for improving access to, engagement with, and the outcomes of, therapeutic treatment. Amongst a wide range of diagnosable mental disorders, affective disorders – such as depression, bipolar and anxiety – are the most common. For these disorders, distortions and inconsistencies in a person’s emotional state (their mood) present the primary cause for disruptions to their life. Here, ML promises to offer new routes for improving the identification of health risk factors; the prediction of disease progression; and the development of personalised health interventions. Research to date has started to explore the identification of mental health problems through inferences about peoples’ behaviours on social media, online searches, or mobile phone app uses; as well as varied approaches to assess, or continuously monitor, a person’s mental health and related symptoms by measuring sleep, mood, stress or physical activity via audio, visual or physiological signal processing.
Despite great potential, the realization of effective ML-enabled applications for mental health remains a hugely challenging area for research and development. Among the very many challenges in this domain are the need for a stronger focus on real-world applications and user-centred design processes to aid the identification of real healthcare needs that can sensibly be supported through ML; and accordingly, careful choices in data collection and the design of reliable and fair algorithmic models. Especially in mental health, where data and ML-supported decisions can have far reaching personal, social and economic impact, we need to be very critical of what reasonable inferences can be drawn from specific data; design interfaces that help people to appropriately interpret system inferences; and ensure that, ultimately, humans remain in control over, and accountable for, important ML-informed decisions.
This workshop seeks to bring together an inter-disciplinary group of researchers and practitioners from academia and industry to discuss the unique opportunities and challenges for developing effective, ethical and trustworthy ML- approaches and interventions for the diagnosis and treatment of affective disorders. The specific focus will be on (but it is not limited to):
We invite submissions of short papers (2-4 pages) in ACII paper format. Submissions will be reviewed by members of the organising and program committee based on relevance to the workshop and potential for contributing to discussions. Workshop proceedings will be published by IEEE Xplore.
Please submit your paper to the "Machine Learning for the Diagnosis and Treatment of Affective Disorders" track via the easychair submission system.

Despite advances in the development of evidence-based mental health interventions, we have seen little movement in the prevalence of mental health disorders. Many have proposed that technology can help address problems in mental health services by making them more accessible, available, and cheaper. However, these proposals have not addressed what might be an unfortunate reality in that mental health services may not be as good as we think. Beyond a lack of engagement, mental health services suffer from a lack of quality and measurement. Advances in machine learning offers the potential to create “smarter” mental health services by improving our way to assess mental health issues and building personalized and more efficacious services. In this talk I will present research focused on both the assessment and treatment of mental health issues through technology including the use of sensor-based technologies to identify mental health issues and the IntelliCare platform, a suite of mini-apps capable of creating personalized sequences of technology-enabled care. I will discuss implications for the application of machine learning to mental health services as well as challenges in the design and implementation of these tools.
Today's mobile phones are far from mere communication devices they were just ten years ago. Equipped with sophisticated sensors and advanced computing hardware, phones can be used to infer users' location, activity, social setting and more. As devices become increasingly intelligent, their capabilities evolve beyond inferring context to predicting it, and then reasoning and acting upon the predicted context. Information about users’ behaviour can also be gathered by means of wearables and IoT devices as well as by sensors embedded in the fabric of our cities. Inference is not only limited to physical context and activities, but in the recent years mobile phones have been increasingly used to infer users' emotional states. The applications of these techniques are several, from positive behavioural intervention to more natural and effective human-mobile device interaction. In this talk I will discuss the work of my lab in the area of mobile sensing for modelling and predicting human behaviour and emotional states. I will present our ongoing projects in the area of mobile systems for mood monitoring and mental health. In particular, I will show how mobile phones can be used to collect and analyse mobility patterns of individuals in order to quantitatively understand how mental health problems affect their daily routines and behaviour and how potential changes in mood can be automatically detected from sensor data in a passive way. Finally, I will discuss our research directions in the broader area of anticipatory mobile computing, outlining the open challenges and opportunities.
Nonverbal behavior is multimodal and interpersonal. In several studies, I addressed the dynamics of facial expression, head, and body movement for emotion communication, social interaction, and clinical applications. Leveraging recent advances in AI and machine learning, my work focuses on developing computational models to automatically analyze, recognize, and interpret multimodal social and communicative behavior. By modeling multimodal and interpersonal communication my work seeks to inform affective computing, social interaction, and behavioral health informatics. In this talk, I will focus on our recent work that has addressed computational methods for multimodal assessment of depression severity in participants undergoing treatment for depression.
Substantial investment from government and commercial organisations in health technology reflects the opportunities to promote uniquely tailored, data-rich and autonomy-supportive tools at scale. Still many digital technologies for health and wellbeing go un-evaluated, lack an evidence base, or fall short of achieving the impact intended. Among the challenges to success is achieving the deep interdisciplinarity involved, which often requires continuous collaboration among medical professionals, psychologists, HCI researchers, user experience designers, software developers and end-users. While some projects lack theoretical grounding or an evidence-base, others fail to involve users effectively in order to understand their needs, perceptions and contexts, resulting in technologies that go unused. Working together, researchers in HCI, health and the social sciences can improve the processes by which digital technologies are developed and distributed for the benefit of population-wide health and wellbeing. In this presentation, I will share some of the multidisciplinary evidence-based approaches to the development of health technologies formerly taken at the Wellbeing Technologies Lab in Sydney, Australia, and now starting at Imperial college London. I will describe some ideas on the contributions HCI can make to this field, and share a number of case studies in the domains of chronic illness, mental health and doctor-patient communication.
