| Abstract | Current indoor location determination systems require an offline training phase in order to build a radio map that contains a list of radio fingerprints at known locations. The process of building this radio map is usually a time-consuming and requires an intensive work where the accuracy of these systems depends on various factors such as the number of collected radio fingerprints and the time in which they were collected. This paper presents an indoor location determination system that does not require a time-consuming offline training phase in order to build the radio map. Instead, the system uses the online phase for both reading the current Received Signal Strength (RSS) and inferring the location values for each random variable using Bayesian Graphical Model (BGM). The proposed system is based on Markov Chain Monte Carlo (MCMC) sampling techniques in order to draw samples from the posterior distribution. We will also introduce the Feed and Infer algorithm to be used in conjunction with the proposed graphical model. The proposed system will be compared with other single-phase systems. |

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.
