| Question 662 |
In Data mining, ______ is a method of incremental conceptual clustering.
| STRING | |
| COBWEB | |
| CORBA | |
| OLAD |
Question 662 Explanation:
→ COBWEB is an incremental system for hierarchical conceptual clustering. COBWEB incrementally organizes observations into a classification tree. Each node in a classification tree represents a class (concept) and is labeled by a probabilistic concept that summarizes the attribute-value distributions of objects classified under the node. This classification tree can be used to predict missing attributes or the class of a new object. There are four basic operations COBWEB employs in building the classification tree.
1. Merging Two Nodes
2. Splitting a node
3. Inserting a new node
4. Passing an object down the hierarchy
→ Common Object Request Broker Architecture (CORBA) is an architecture and specification for creating, distributing, and managing distributed program objects in a network. It allows
programs at different locations and developed by different vendors to communicate in a network through an “interface broker.” CORBA was developed by a consortium of vendors through the Object Management Group (OMG), which currently includes over 500 member companies.
→ STRING and OLAD is irrelevant options.
