Pattern Recognition

Closely related to the concept of Machine Learning, Pattern Recognition is the assignment of an output value, termed a label, to a given input value, termed an instance. This is achieved through the application of an algorithm, which usually falls into one of two general categories (although mixed techniques are beginning to be developed): supervised (requires a training set), and unsupervised,...

Pattern Recognition

Pattern recognition stems from the need for automated machine recognition of objects, signals or images, or the need for automated decision-making based on a given set of parameters. Despite over half a century of productive research, pattern recognition continues to be an active area of research because of many unsolved fundamental theoretical problems as well as a rapidly increasing number of...

Pattern recognition

LDA (Linear Discriminant Analysis) is a data discrimination technique that seeks the transformation to maximize the ratio of the scatter between classes and the scatter within each class. Although it has been applied to several applications successfully, it has two limitations that (i) it fails to discriminate the data with complex distributions since each class data is assumed to be distribute...
