Thus, the identification of potential DDIs is essential for doctors, patients and the society. Existing traditional machine learning models rely heavily on handcraft features and lack generalization. Recently, the deep learning approaches that can automatically learn drug features from the molecular graph or drug-related network have improved the ability of computational models to predict unknown DDIs. However, previous works utilized large labeled data and merely considered the structure or sequence information of drugs without considering the relations or topological information between drug and other biomedical objects (e.g. gene, disease and pathway), or considered knowledge graph (KG) without considering the information from the drug molecular structure.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Accordingly, to effectively explore the joint effect of drug molecular structure and semantic information of drugs in knowledge graph for DDI prediction, we propose a multi-scale feature fusion deep learning model named MUFFIN. MUFFIN can jointly learn the drug representation based on both the drug-self structure information and the KG with rich bio-medical information. In MUFFIN, we designed a bi-level cross strategy that includes cross- and scalar-level components to fuse multi-modal features well. MUFFIN can alleviate the restriction of limited labeled data on deep learning models by crossing the features learned from large-scale KG and drug molecular graph. We evaluated our approach on three datasets and three different tasks including binary-class, multi-class and multi-label DDI prediction tasks. The results showed that MUFFIN outperformed other state-of-the-art baselines.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Availability and implementation<\/jats:title>\n                  <jats:p>The source code and data are available at https:\/\/github.com\/xzenglab\/MUFFIN.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/bioinformatics\/btab169","type":"journal-article","created":{"date-parts":[[2021,3,11]],"date-time":"2021-03-11T12:24:05Z","timestamp":1615465445000},"page":"2651-2658","source":"Crossref","is-referenced-by-count":177,"title":["MUFFIN: multi-scale feature fusion for drug\u2013drug interaction prediction"],"prefix":"10.1093","volume":"37","author":[{"given":"Yujie","family":"Chen","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, Hunan University , Changsha 410012, China"}]},{"given":"Tengfei","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Hunan University , Changsha 410012, China"}]},{"given":"Xixi","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Hunan University , Changsha 410012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8910-0929","authenticated-orcid":false,"given":"Jianmin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Hunan University , Changsha 410012, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1479-5399","authenticated-orcid":false,"given":"Bosheng","family":"Song","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Hunan University , Changsha 410012, China"}]},{"given":"Xiangxiang","family":"Zeng","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Hunan University , Changsha 410012, China"}]}],"member":"286","published-online":{"date-parts":[[2021,3,15]]},"reference":[{"key":"2023051609171039300_btab169-B1","doi-asserted-by":"crossref","first-page":"706","DOI":"10.1016\/j.jbi.2008.03.004","article-title":"Bio2RDF: towards a mashup to build bioinformatics knowledge systems","volume":"41","author":"Belleau","year":"2008","journal-title":"J.
