About this paper
Gangsu Kim, Won-Ki Jeong
LaGuadia, a language-guided adaptive distillation framework, enables a compact (87M parameter) student model to effectively learn from multiple large Pathology Foundation Models. This approach achieved performance comparable to or superior to significantly larger PFMs (e.g., GigaPath 1.13B) across generative and discriminative pathology tasks, enhancing factual consistency and generalization by leveraging clinical language reports as a semantic guide.
Key insights
- Clinical linguistic reports serve as an effective objective semantic anchor for guiding knowledge distillation, enabling more context-aware and diagnostically relevant knowledge transfer compared to purely visual or uniformly weighted multi-teacher approaches.
- Adaptive weighting of multi-teacher contributions based on semantic alignment with clinical narratives effectively resolves potential knowledge conflicts among disparate teachers, leading to more robust student models.
- A compact student model can achieve comparable or superior performance to significantly larger Pathology Foundation Models across diverse tasks by leveraging sophisticated, language-guided distillation, demonstrating parameter efficiency without sacrificing representational power.
