AI 4 Continuous Learning

About the Group

AI 4 Continuous Learning is dedicated to developing and applying adaptive artificial intelligence systems to study ageing as a continuous, lifelong process. The group investigates how continuous, lifelong learning models can capture dynamic, nonlinear changes in biological, clinical, and functional states across the lifespan.

By treating ageing as a time-evolving phenomenon, the group moves beyond static disease models, enabling AI systems that learn from longitudinal and multimodal data while preserving knowledge over time.

Vision & Impact

AI 4 Continuous Learning contributes to MIA-Portugal's mission by positioning AI as a core enabler for understanding ageing across the lifespan. By developing adaptive, interpretable, and privacy-preserving AI systems, the group aims to support early prevention, personalised interventions, and healthier ageing at both individual and population levels

Mission and Research Aims

The mission of AI 4 Continuous Learning is to advance AI-driven ageing research by designing lifelong, interpretable, and trustworthy learning systems. The group aims to:

  • Model ageing as a continuous adaptive process rather than a set of isolated conditions.
  • Develop a continuous, lifelong-learning AI capable of evolving with new data, settings, and populations.
  • Integrate AI with biomedical, clinical, and population-level ageing data.
  • Support personalised prevention and intervention strategies for healthy ageing.
  • Promote responsible, transparent, and human-centric AI in biomedical research.

Research Areas

  • The group conducts interdisciplinary research at the intersection of artificial intelligence, ageing research, and precision medicine. Core research areas include:
  • Continuous & Lifelong Learning AI
  • Development of adaptive models that learn over time without catastrophic forgetting, enabling robust longitudinal modelling.
  • AI-Based Modelling of Ageing Trajectories
  • Representation of ageing as a dynamic process across molecular, physiological, behavioural, and clinical scales
  • Distributed & Privacy-Preserving Learning
  • Distributed learning frameworks for collaborative research across institutions while preserving data privacy.
  • Interpretable & Trusted AI
  • Explainable and reliable models to support biological insight, clinical understanding, and decision-making.
  • AI for Prevention & Intervention Design
  • Data-driven simulation and optimisation of personalised interventions and timing to improve long-term outcomes.
