Researchers have developed NarraSpace, a novel system designed to improve dementia classification by grounding language model predictions in visual scene evidence. This system links words and speech times to specific picture elements and retrieves relevant utterances, providing narrative-spatial descriptors that summarize coverage and temporal organization. NarraSpace connects event-indexed language model measurements to their source utterances and speech timing, enabling clinicians to review quantitative summaries alongside original speech evidence. A fixed support vector classifier using NarraSpace achieved 80.88% mean accuracy on a benchmark test set for Alzheimer's disease classification. AI
IMPACT This research could lead to more interpretable and reliable AI-driven diagnostic tools for dementia by grounding predictions in concrete evidence.
