From free association to free parameters: machine-learning empowers artificial intelligence models to rate the affective-relational aspects of narratives like an expert psychologist
Background Narrative assessment offers unique insight into psychological functioning but is resource-intensive, requiring extensive expert training and time. Recent work suggests Artificial Intelligence (AI), including moderately sized, adaptable large language models (LLMs), can master narrative assessment's complex, multi-step scoring rules. This study examined whether fine-tuning could enable AI raters to accurately assess narratives. Method We fine-tuned five diverse LLMs (3–7 billion parameters) on two dataset …
