in research outputs both quality and quantity are of critical value and evaluation of both aspects is required for best evaluation. several studies have worked on single or two-dimensional methods that provide the assessment of quality, quantity or both simultaneously in different branches of sciences, but none of them have played a role in a particular area of medicine. this study has been con...

The optimal storage capacity of a perceptron with a finite fraction of sign constrained weights, which are prescribed a priori, is examined. The storage capacity is calculated by considering the fractional volume of weights which can store a set of a N random patterns, where N is the size of the input. It is found that in the case where (1 s ) N weights are sign constrained the capacity is (1 +...

SIERRa is a program that learns procedures incrementally from examples, where an example is a sequence of actions. StERRA learns by completing explanations. Whenever the current procedure is inadequate for explaining (parsing) the current example, SIERRA formulates a new subprocedure whose instantiation completes the explanation (parse tree). The key to SIERRA'S success lies in supplying a smal...
