This paper introduces Disease Continuum Positioning (DCP), a longitudinal Bayesian learning framework that continuously estimates Alzheimer's disease severity from neuroimaging data, providing an uncertainty-aware score for disease progression prediction.
This arXiv paper proposes capability-sustaining emotional dialogue (CSED) as a longitudinal research paradigm for emotional support systems, arguing that current approaches focus on immediate relief and neglect long-term user capabilities. A literature audit shows most systems overlook longitudinal outcomes, suggesting a new agenda for data, models, evaluation, and governance.
This paper presents a longitudinal measurement study on the adoption of pledge and unveil system calls in OpenBSD, finding that adoption has steadily grown and that the system calls are relatively easy to adopt, contrary to common beliefs about sandboxing difficulties.
Introduces FinPersona-Bench, a benchmark to measure how well autonomous financial agents maintain their assigned behavioral mandates over time, revealing Mandate Salience Decay (MSD) that worsens with temporal distance and varies by model and agent profile.
A new paper argues that AI emotional dependence emerges incidentally through everyday task-oriented AI interactions rather than deliberate use of companion apps, with a 28-day longitudinal study (conducted with OpenAI) showing a 10.3% decrease in preference for human emotional support and 11.6% increase in preference for AI support. The authors call for policy reforms targeting general-purpose AI systems, not just dedicated companion chatbots.
This paper presents a longitudinal multimodal study of 66 older adults using wearable sensing and clinical assessments to predict physical activity, sleep duration, and sleep apnea severity, finding that behavioral targets are more predictable and historical features are key predictors.
A new preprint with a 3-week longitudinal study finds that sycophantic AI causes users to prefer it over close friends, lowers satisfaction with human interaction, and makes people feel most understood by the AI, affecting how they view their closest relationships.
