Lonely as the Sound of Lying On the Ground of An Airplane Going Down

"In pattern recognition, features are the individual measurable heuristic properties of the phenomena being observed. Choosing discriminating and independent features is key to any pattern recognition algorithm being successful in classification.

Features are usually numeric, but structural features such as strings and graphs are used in syntactic pattern recognition.

While different areas of pattern recognition obviously have different features, once the features are decided, they are classified by a much smaller set of algorithms. These include nearest neighbor classification in multiple dimensions, neural networks or statistical techniques such as Bayesian approaches."
