Subset selection strategy

چکیده
J. Chemom A new technique for representative subset selection is presented. The advocated method selects unambiguously the most important objects among the calibration set and uses this subset for themodel development without significant deterioration in the predictive ability. Themethod is called boundary subset selection and it is an inherent part of the Simple Interval Calculation (SIC) approach. SIC is a method for linear modeling, which is based on the assumption of error boundedness. The primary SIC consequence is an object status classification (OSClas) that reveals the most influential objects and also designates the most stable and reliable ones. The OSClas is used as the main tool for representative subset selection. The presented results are compared with widely used Kennard–Stone algorithm and D-optimal design procedure employing three real-world examples. Copyright 2008 John Wiley & Sons, Ltd.

The increasing complexity of decision making in a severely dynamic competitive environment of the universe has urged the wise managers to have relevant strategic plans for their firms. Strategy is not formulated from one criterion but from multiple criteria in environmental scanning, and often, considering all of them is not possible. A list of criteria utilizing Delphi was selected by consu...
متن کاملA Parallel Genetic Algorithm Based Method for Feature Subset Selection in Intrusion Detection Systems
Intrusion detection systems are designed to provide security in computer networks, so that if the attacker crosses other security devices, they can detect and prevent the attack process. One of the most essential challenges in designing these systems is the so called curse of dimensionality. Therefore, in order to obtain satisfactory performance in these systems we have to take advantage of app...

Introduction: Amajor problem in the treatment of cancer is the lack of an appropriate method for the early diagnosis of the disease. The chemical reaction within an organ may be reflected in the form of proteomic patterns in the serum, sputum, or urine. Laser mass spectrometry is a valuable tool for extracting the proteomic patterns from biological samples. A major challenge in extracting such ...
