1) Canonical correlation analysis (CCA) is a statistical method that analyzes the correlation relationship between two sets of multidimensional variables.
2) CCA finds linear transformations of the two sets of variables so that their correlation is maximized. This can be formulated as a generalized eigenvalue problem.
3) The number of dimensions of the transformed variables is determined using Bartlett's test, which tests the eigenvalues against a chi-squared distribution.
The document discusses pattern recognition and classification. It begins by defining pattern recognition as a method for determining what something is based on data like images, audio, or text. It then provides examples of common types of pattern recognition like image recognition and speech recognition. It notes that while pattern recognition comes easily to humans, it can be difficult for computers which lack abilities like unconscious, high-speed, high-accuracy recognition. The document then discusses the basic principle of computer-based pattern recognition as classifying inputs into predefined classes based on their similarity to training examples.
