Abstract | A novel control chart pattern recognition system using support vector machine(SVM) is presented. Pattern recognition techniques have been wildly applied to identify abnormal patterns in control charts. Abnormal patterns exhibited by such charts can be associated with certain assignable causes affecting the process. Most of the existing recognition method are capable of recognizing a single abnormal pattern, however, a practical situation is concurrent patterns where two abnormal patterns may exist together. The presented method can enhance recognition capability and accuracy, and avoid the disadvantages, such us over-fitting, weak normalization capability, etc., of artificial neural network(ANN) method. Furthermore, it can recognize these hybrid abnormal patterns existing in control chart by combining voting and binary tree methods. Simulation experimental results are given to demonstrate that, compared with ANN recognition methods, the method proposed is superior in classifying shift, trend and cyclic patterns, and realized the recognition for hybrid abnormal pattern in control charts. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
