How It Works
PsyEvo operates through three innovative components. The Hierarchical Bayesian Skill Policy (HBSP) personalizes interventions by updating a skill posterior for each client based on session feedback.
Inter-session Listwise Preference Optimization (LiPO) refines how these skills are expressed by learning from preferences across multiple clients. Finally, State-conditioned Ordinal Credit Assignment (SOCA) evaluates and assigns credit to the skills and responses, ensuring that the model adapts effectively to client needs.
