Pattern cognition

This technique allows the simultaneous treatment of about m — 3 to about m — 10 features for the visual assessment of similarities or dissimilarities of n objects. The m features are arranged as vectors with one starting point in a star. Values of the features (star axis) can be connected and a star is formed. Each object is represented as one star. Similarities between the objects are easily seen and human imagination is only necessary for pattern cognition.

In this chapter we have only addressed a selected number of topics and for lack of space we have left out many others. Cluster analysis has played a larger role in QSAR than appears from our overview. This technique is an established QSAR tool in recognition or classification of known patterns [38,60] as well as for cognition or detection of novel patterns [61]. 

Fetal alcohol syndrome (FAS) is a pattern of birth defects caused by maternal consumption of ethanol during pregnancy. It is recognized by growth deficiency, a characteristic set of craniofacial features and neurodevelopmental abnormalities leading to cognitive and behavioral deficits [85]. FAS is considered to be the most common non-hereditary cause of mental retardation.
