The Importance of Experience in Clinical Reasoning
Clinical expertise develops not only from medical education but also from a wealth of real-world experience. Practitioners build a repository of diagnostic patterns based on past case evaluations. Existing large language models (LLMs) have made notable strides in assisting clinicians. However, many of these models evaluate cases independently, thus missing out on the collective wisdom accumulated over countless diagnoses. The SEA agent addresses this shortcoming by implementing a self-learning framework, ensuring that experiences are not merely processed but also continuously adapted and improved upon.
The Dual-Memory Module: A Cognitive Approach
At the heart of SEA’s innovation is its dual-memory module, which is designed to mimic cognitive processes. This module allows the agent to not only retrieve relevant knowledge but also categorize and adapt learned experiences. By doing so, SEA can effectively create reusable diagnostic rules. This cognitive architecture is paramount as it enables SEA to manage its memory and utilize past experiences more efficiently, leading to improved diagnostic accuracy.
Reinforcement Training Framework
To maximize the potential of the SEA agent, the developers have crafted a specialized reinforcement training framework. This innovative approach facilitates the joint optimization of reasoning skills and memory management. The framework is designed to ensure that as SEA learns from each case, it simultaneously refines its diagnostic algorithms and solidifies its memory of previous experiences. This synergy between reasoning and memory is critical in advancing clinical decision-support systems, making SEA distinct from standard diagnostic tools.
Performance Evaluation on MedCaseReasoning
One of the significant highlights of SEA’s capabilities is its performance on the MedCaseReasoning dataset. The results are astounding: SEA achieved an accuracy of 92.46%, significantly surpassing the strongest baseline by a substantial margin of 19.6%. This impressive outcome underscores the effectiveness of jointly optimizing reasoning and memory—demonstrating that a well-integrated approach can yield superior diagnostic tools.

Long-Horizon Evaluation with ER-Reason
Beyond standard evaluations, SEA’s potential shines on long-horizon assessments, particularly through the ER-Reason dataset. Here, SEA reached a final accuracy of 0.7214, showcasing both the reliability and robustness of the agent in varied conditions. The improvement margin of +0.35 Acc@100 further illustrates that while baseline methods struggle with stability, SEA delivers consistent and meaningful advancements in diagnostic accuracy over time.
Expert Evaluation and Practical Implications
Expert evaluations play a crucial role in validating a diagnostic agent’s effectiveness and credibility. The rules synthesized from SEA have received praise for their clinical correctness and usefulness, establishing a trust factor in the induced rules within the dual-memory module. Such assessments highlight that the operational mechanisms of SEA are not merely theoretical but are grounded in practical applicability, making them beneficial for clinicians who rely on evidence-based practices.
Transforming Experience into Knowledge
In essence, SEA exemplifies a paradigm shift in how diagnostic agents operate. By efficiently transforming diverse experiences into actionable knowledge, SEA not only enhances diagnostic reasoning but also supports continuous learning. The implications of such advancements are profound—it signifies a future where AI can continually evolve to better serve clinicians and, by extension, patients.
Conclusion: Advancing AI in Healthcare
The development of SEA heralds a new era for AI in healthcare, where self-learning and memory optimization converge to create powerful diagnostic tools. As the landscape of clinical decision-making evolves, innovations like SEA ensure that experience remains at the forefront, reinforcing that the journey of learning and adaptation is crucial in the medical field.
