Web14 de abr. de 2024 · Early attempts use sequential models [1,2,3, 12, 13] to encode sequences of visits, but lack consideration of complex relationships between diseases.Thus some works [5, 8, 14] introduce external medical knowledge to capture complex relationships between diseases, but they ignore the hierarchical structure of EHR … WebThe existing KT models have gradually achieved improvements in prediction performance. However, they do not well simulate working memory and long-term memory in human memory mechanism, which is closely related to learning process. In our paper, we propose a Hierarchical Memory Network (HMN) to fit human memory mechanism better in KT.
Web17 de jul. de 2024 · A network database structure is an extension of the hierarchical database structure. In this model, the data elements of a database are organized in the form of parent-child relationships and all types of relationships among the data elements must be determined when the data is the first design. Web14 de out. de 2024 · We perform large-scale training with this hierarchical GMM based loss function and introduce a natural gradient descent algorithm to update the parameters of the hierarchical GMM. With a single deterministic neural network, our uncertainty quantification approach performs well when training and testing on large datasets.
Web26 de jan. de 2024 · The relational model was an advancement from the once-common network and hierarchical database models. They differ in a few ways: The relational model allowed people to access data via a direct relationship between files, rather than by paths to and from files, so new relations between files could easily be added. While the hierarchical database model structures data as a tree of records, with each record having one parent record and many children, the network model allows each record to have multiple parent and child records, forming a generalized graph structure. This property applies at two levels: the schema is a generalized graph of record types connected by relationship types (called "set types" in CODASYL), and the database itself is a generalized graph of record occurrences …
