AI-Wired Projects
Our AI-Wired Projects aim to build the next generation of AI-informed, expert-driven clinical decision support tools for aphasia rehabilitation. Although the Western Aphasia Battery–Revised (WAB-R) is widely used to classify aphasia, clinicians consistently report that individuals with the same aphasia type show highly diverse language profiles. As a result, treatment selection often varies significantly across clinicians, limiting consistency, transparency, and scalability in clinical practice.
This research program addresses that challenge by examining how experts make treatment decisions and how AI systems can learn from these decisions to support evidence-based, individualized care. In this project, licensed speech-language pathologists and aphasia researchers review anonymized WAB-R profiles and select treatments using a structured checklist. Their decisions are compared with both rule-based AI recommendations and supervised machine-learning models trained on expert responses.
We analyze inter-rater agreement, human–AI alignment, and machine-learning feasibility to determine how expert clinical reasoning can be transformed into structured, explainable, and scalable frameworks for rehabilitation planning. This work lays the foundation for developing AI-supported treatment recommendation systems that enhance decision-making for clinicians, support early-career practitioners, and improve the reliability of aphasia care.
