In comparison to the hierarchical model, data can be retrieved faster. This is because the data in the network model is more related, and there may be more than one path to a given node. As a result, the data can be accessed in a variety of ways. Data integrity is present since there is a parent-child relationship.

WebThe hierarchical network model for semantic memory was proposed by Quillian et al. In this model, the primary unit of LTM is concept. Concepts are related to one another and then form a hierarchical structure. As shown in Fig. 8.5, the block is a node representing concept, and the line with an arrow point expresses the dependence between the concepts.

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. WebConvolutional neural networks (CNNs) have made significant advances in remote sensing scene classification (RSSC) in recent years. Nevertheless, the limitations of the receptive field cause CNNs to suffer from a disadvantage in capturing contextual information.

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 … http://hnm.stat.cmu.edu/
