| Abstract | Control chart pattern analysis is a crucial task in statistical process control. There are various types of nonrandom patterns that may appear on the control chart indicating that the process is out of control. The presence of nonrandom patterns manifests that a process is affected by assignable causes, and corrective actions should be taken. From a process control point of view, identification of nonrandom patterns can provide clues to the set of possible causes that must be searched; hence, the troubleshooting time could be reduced in length. In this paper, we discuss two implementation modes of control chart pattern recognition and introduce a new research issue concerning pattern displacement problem in the process of control chart analysis. This paper presents a neural network-based pattern recognizer with selected features as inputs. We propose a novel application of statistical correlation analysis for feature extraction purposes. Unlike previous studies, the proposed features are developed by taking the pattern displacement into account. The superior performance of the feature-based recognizer over the raw data-based one is demonstrated using synthetic pattern data. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
