| Abstract | Cloud computing is an elastic computing model that the users can lease the resources from the rentable infrastructure. Cloud computing is gaining popularity due to its lower cost, high reliability and huge availability. To utilize the powerful and huge capability of cloud computing, this paper is to import it into data mining and machine learning field. As one of the most influential and open competition in machine learning area, Netflix Prize attached with mass storage had driven thousands of teams across the world to attack the problem, among which the final winner was BellKor’s Pragmatic Chaos team, who bested Netflix’s own algorithm for predicting ratings by 10%. Their solution is an ensemble of a large number of models, each of which specializes in addressing a different aspect of the data. Among such different models, k-nearest neighbors (KNN) and Restricted Boltzmann Machine (RBM) are reported to be two most important and successful models. As a result, we build two predictors based on such two model respectively with the order to testify their performance based on cloud computing platforms. The results show that KNN can achieve root mean square deviation (rmse) with 0:9468 after the Global Effect (GE) data preprocessing, which is better than the Cinematch’s performance with rmse being 0:951. The rmse for RBM algorithm is about 0:9670 on the raw dataset, which can be further improved by KNN model. |

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.
