Example Of Data Summarization

Decent Essays

• Characterization: is a summary of common features of items in a target class, and yields what is known as characteristic rules. The information pertinent to a user-specified class are usually retrieved by a database request and run through a summarization segment to mine the soul of the data at diverse levels of mining. For example, one may want to illustrate the OurVideoStore clienteles who frequently lease more than 30 movies a year. With conception chain of command on the traits describing the objective class, the trait based induction technique can be used, for example, to carry out data summarization.
• Discrimination: It produces what is known as discriminant rules and is essentially the comparison of the common traits of items …show more content…

• Classification: It is the association of information in given classes. Also called supervised classification, the cataloguing uses given class tags to edict the items in the information collection. Classification line of attack normally use a training set where all items are already linked with known class tags. The classification algorithm acquires from the training set and builds a model. The model is used to categorize new items. For instance, after starting a credit dogma, the OurVideoStore executives could examine the clients’ behaviors vis-à-vis their credit, and tag consequently the clienteles who established credits with three possible tags “safe”, “risky” and “very risky”. The cataloguing analysis would generate a model that could be used to either accept or reject credit appeals in the future.
Prediction: It has engrossed substantial consideration given the possible implications of fruitful predictions in a commercial context. There are two main types of predictions: one can either try to predict some unobtainable or unavailable data values or undecided trends, or predict a class tag for some data. The latter is knotted to classification. Once a cataloguing model is built grounded on a training set, the class tag of an item can be predicted based on the trait values of the item and the trait values of the classes. Prediction is however more often denoted to the prediction of missing statistical
