I want to know what is metadata and what is meant by meta features?
When I google Meta Features what I get is feature selection tool called Meta-Feature. What is the function of feature selection tools ?
Also, what I want is the definition and meaning of the meta features ?
Topic classification metadata feature-extraction feature-selection clustering
Category Data Science
Gramatically "Meta" comes from greek and means beyond something. "Meta-Feature" means beyond the feature.
Normally refers to how the feature was obtained, the uncertainty, error measurements... For example, in atmospheric modeling, for the features "Temperature" you can have a lot of different meta features like, with which tool are you measuring the temperature? what is the error of the tool? in which conditions is the measurement happening?
I understand the term meta feature as a generalization of this concept but in Data Science.
