WebHierarchical model. b. Network model. c. Relational model (a) Hierarchical model: This model presents data to users in a hierarchy of data elements that can be represented in a sort of inverted tree. In a sales order processing system, a customer may have many invoices raised to him and each invoice may have different data elements. Hierarchical network models are iterative algorithms for creating networks which are able to reproduce the unique properties of the scale-free topology and the high clustering of the nodes at the same time. These characteristics are widely observed in nature, from biology to language to some social networks.

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. WebHierarchical Data Model: Network Data Model: Relational Data Model: 1.
