摘要:

与许多其他领域相比,健康服务中的推荐系统可能特别受益于健康领域知识的整合,因为它有助于提供有意义的和个性化的推荐,以满足个人的健康需求。随着表示学习的最新进展,使健康知识的分层嵌入到双曲庞加莱空间,这项工作提出了一个基于内容的推荐系统,在初级保健的基础上,病人的健康档案,丰富的预训练庞加莱嵌入的ICD-9代码通过迁移学习。建议的模型优于传统的同行在推荐准确性方面,并有几个重要的商业影响,改善医患关系。

英文摘要:

In contrast to many other domains, recommender systems in health services may benefit particularly from the incorporation of health domain knowledge, as it helps to provide meaningful and personalised recommendations catering to the individual's health needs. With recent advances in representation learning enabling the hierarchical embedding of health knowledge into the hyperbolic Poincare space, this work proposes a content-based recommender system for patient-doctor matchmaking in primary care based on patients' health profiles, enriched by pre-trained Poincare embeddings of the ICD-9 codes through transfer learning. The proposed model outperforms its conventional counterpart in terms of recommendation accuracy and has several important business implications for improving the patient-doctor relationship.
