- Classifier (mathematics)
mathematics, a classifier is a mapping from a (discrete or continuous) feature space"X" to a discrete set of labels "Y".
The applications of classifiers are wide-ranging. They find use in medicine (drug trial analysis,
MRI data analysis), finance (share analysis, index prediction), mobile phones ( signal decoding, error correction), computer vision( face recognition, target tracking), voice recognition, datamining(supermarket purchasing analysis, retail customer analysis) and uncountable other areas.
An example is a classifier that accepts a persons salary details, age, marital status, home address and credit history and classifies the person as acceptable/unacceptable to receive a new credit card or loan.
