An Edge-Host-Cloud Architecture for Robot-Agnostic, Caregiver-in-the-Loop Personalized Cognitive Exercise: Multi-Site Deployment in Dementia Care
Wenzheng Zhao, Ruth Palan Lopez, Shu Fen Wung +1
We present Speaking Memories, a distributed, stakeholder-in-the-loop robotic interaction platform for personalized cognitive exercise support. Rather than a single robot-centric sy…
An Interactive LLM-Based Simulator for Dementia-Related Activities of Daily Living
Kruthika Gangaraju, Shu-Fen Wung, Kevin Berner +2
Effective dementia caregiving requires training and adaptive communication, but assistive AI and robotics are constrained by a lack of context-rich, privacy-sensitive data on how p…
Causal Reinforcement Learning based Agent-Patient Interaction with Clinical Domain Knowledge
Wenzheng Zhao, Ran Zhang, Ruth Palan Lopez +2
Reinforcement Learning (RL) faces significant challenges in adaptive healthcare interventions, such as dementia care, where data is scarce, decisions require interpretability, and…
Smarter Together: Combining Large Language Models and Small Models for Physiological Signals Visual Inspection
Huayu Li, Zhengxiao He, Xiwen Chen +8
Large language models (LLMs) have shown promising capabilities in visually interpreting medical time-series data. However, their general-purpose design can limit domain-specific pr…
