Study Notes
Data Mining and Machine Learning Terminology
- An attribute is also referred to as a feature or variable in Data Mining and Machine Learning.
- In a given data set, an attribute that is an example of a nominal type is one that has no inherent order or ranking, such as marital status or occupation.
Attributes and Attribute Values
- Attribute values are the specific instances of an attribute, whereas the attribute itself is the characteristic or property being measured.
- For example, "eye color" is an attribute, while "blue" and "brown" are its attribute values.
Nominal Attributes
- Nominal attributes include examples like ID numbers and eye color, which are categorical and have no inherent order or ranking.
Objects in Data Mining and Machine Learning
- An object is also referred to as a record, tuple, or data point in Data Mining and Machine Learning, and it represents a single instance or observation.
