| Abstract | Proposes a multiple hypothesis approach for building and maintaining a world model for an autonomous robot vehicle. Dynamic world modeling requires the integration of multiple sensor observations obtained from multiple vehicle locations at different times. A crucial problem in this interpretation task is the presence of uncertainty in the origins of measurements (data association uncertainty) as well as in the values of measurements (noise uncertainty). The extended Kalman filter (EKF) has seen widespread use in robotics for dealing with the latter problem. The multiple hypothesis filter combines the basic machinery of the EKF with a rigorous Bayesian probabilistic data association framework in which to address temporal and spatial data association uncertainty. For dynamic world modeling, the approach results in multiple world models at a given time step, each one representing a possible interpretation of all past and current measurements and each having an associated probability. A single unified world model can be constructed by integrating all of the hypotheses to form a single hypothesis.< |

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.
