| Abstract | According to Domingos’ bias–variance decomposition framework, we study the bias–variance characteristics of the standard Multiple Criteria Linear Programming (MCLP) classification method. The experimental results show that, under Domingos’ bias–variance decomposition framework, bias is much bigger than variance, and boosting ensemble doesn’t behave better than bagging ensemble, and increasing training example can effectively reduce variance rather than bias. We conclude that MCLP intrinsically is a stable classification method, and that an appropriate ensemble method for MCLP rests with the characteristics of a specific data set. When data can be easily linearly separated, MCLP will have low bias and bagging can be employed to lessen variance. When data present complicated no-linear structure, MCLP will have high bias and boosting ensemble can be considered to reduce bias. But, when boosting is used, noises and over fitting should be considered. |

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.
