前言
Advances in data generation and collection are producing data sets of massire size in commerce and a variety of scientific disciplines.Data warehouses store details of the sales and operations of businesses,Earth-orbiting satelfites beam high-resolution images and sensor data back to Earth.and genomics ex- periments generate sequence,structural,and functional data for an increasing number of organisms.The ease with Which data can now be gathered and stored has created a new attitude toward data analysis:Gather whatever data you can whenever and wherever possible.It has become an article of faith that the gathered data will have value.either for the purpose that initially motivated its collection or for purposes not yet envisioned.The field of data mining grew out of the limitations of current data analysis techniques in handling the challenges posed by these new types of data sets.Data mining does not replace other areas of data analysis,but rat.Her takes them as the foundation for much of its work.While some areas of data mining,such as association analysis,are unique to the field,other areas,such as clustering,classification, and anomaly detection,build upon a long history of work on these topics in other fields.Indeed.the willingness of data mining researchers to draw upon existing techniques has contributed to the strength and breadth of the field,as well as to its rapid growth.

章节摘录
插图:What Is an attribute?We start with a more detailed definition of an attribute.Definition 2.1. An attribute is a property or characteristic of an object that may vary, either from one object to another or from one time to another.For example, eye color varies from person to person, while the temperature of an object varies over time. Note that eye color is a symbolic attribute with a small number of possible values brown, black, blue, green, hazel, etc.}, while temperature is a numerical attribute with a potentially unlimited number of values.At the most basic level, attributes are not about numbers or symbols. However, to discuss and more precisely analyze the characteristics of objects, we assign numbers or symbols to them. To do this in a well-defined way, we need a measurement scale. Definition 2.2. A measurement scale is a rule (function) that associates a numerical or symbolic value with an attribute of an object.Formally, the process of measurement is the application of a measurement scale to associate a value with a particular attribute of a specific object. While this may seem a bit abstract, we engage in the process of measurement all the time. For instance, we step on a bathroom scale to determine our weight, we classify someone as male or female, or we count the number of chairs in a room to see if there will be enough to seat all the people coming to a meeting. In all these cases, the "physical value" of an attribute of an object is mapped to a numerical or symbolic value.With this background, we can now discuss the type of an attribute, a concept that is important in determining if a particular data analysis technique is consistent with a specific type of attribute.
