How does knowledge grow? It may reorganize itself by which conclusions become explicit that were hidden before. Some rules are needed to make this consistent. These rules should be known as well. So next to the knowledge specific for some topic, say biology, transformation rules have to be available. Examples of such rules are arithmetic and logic….

We see an object and we know what it is: a tree, a table, a pen. There is no doubt. Only in a new, unfamiliar environment like a museum, a scientific lab, an industrial workshop, we may see unknown objects and an explanation is need. But in daily life we recognize the objects, even if we…
What is the core business of pattern recognition?

Around 2000 Fabio Roli raised the question “what is the core business of pattern recognition?”. Given very related areas like machine learning, statistical decision theory and neural networks it became natural, and even urgent to wonder about the identity of the field of pattern recognition. These fields are all dealing with learning from examples, with…

Pattern recognition may be considered both as a science and an art and every scientist in this field possesses such an art as well. It is better explained here. The scientist can read, recognize people, understand speech and learn new patterns every day. Moreover, in his work as a scientist in pattern recognition he uses…
The art and science of pattern recognition

In 1978 Godfried Toussaint announced his intention to write a book on “the art and science of pattern recognition” (the final words of a paper on the use of context in pattern recognition [1]). In 1983 George Nagy used the same expression, but now in an ironic way when he criticized the way pattern recognition…

This post is an excerpt from R.P.W. Duin and E. Pekalska, The Science of Pattern Recognition; Achievements and Perspectives, in: W. Duch, J. Mandziuk (eds.), Challenges for Computational Intelligence, Studies in Computational Intelligence, vol. 63, Springer, 2007, 221-259. In science, new knowledge is phrased in terms of existing knowledge. The starting point of this process…
What is pattern recognition?

For a very small child a walk into the world is a walk into the wild: all is new and exciting. Every object, every sound, every shape provides a new experience. Consequently, he doesn’t know how to interpret what is happening. He doesn’t know how to hold an item or how to walk. That is…
