Statistical Pattern Recognition Paradigm Approach
The SHM problem can be addressed in the context of a statistical pattern recognition paradigm. This paradigm can be broken down into four parts: (1) Operational Evaluation, (2) Data Acquisition and Cleansing, (3) Feature Extraction and Data Compression, and (4) Statistical Model Development for Feature Discrimination. When one attempts to apply this paradigm to data from real world structures, it quickly becomes apparent that the ability to cleanse, compress, normalize and fuse data to account for operational and environmental variability is a key implementation issue when addressing Parts 2-4 of this paradigm. These processes can be implemented through hardware or software and, in general, some combination of these two approaches will be used.

Famous quotes containing the words pattern, recognition, paradigm and/or approach:
“In almost every marriage there is a selfish and an unselfish partner. A pattern is set up and soon becomes inflexible, of one person always making the demands and one person always giving way.”
—Iris Murdoch (b. 1919)
“I shall earnestly and persistently continue to urge all women to the practical recognition of the old Revolutionary maxim. “Resistance to tyranny is obedience to God.””
—Susan B. Anthony (1820–1906)
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
“Genuine polemics approach a book as lovingly as a cannibal spices a baby.”
—Walter Benjamin (1892–1940)
