Research questionHow can reward-based fine-tuning preserve fine-grained fidelity and semantic consistency in conditional medical images?Conditional medical image generators may produce images that match broad semantics while missing clinically relevant intensity, texture, or structural details. A single scalar reward can conflate these failure modes and provide weak guidance for improving them.
