Abstract | In learning from demonstration (LfD) a human trainer demonstrates desired behaviors to a robotic agent, creating a training set that the agent can learn from. LfD allows non-programmers to easily and naturally train robotic agents to perform specific tasks. However, to date most LfD has focused on single robot, single trainer paradigms leading to bottlenecks in both the time required to demonstrate tasks and the time required to learn behaviors. A previously untested, approach to addressing these limitations is to use distributed LfD with a distributed, evolutionary algorithm. Distributed on-board learning is a model for robust real world learning without the need for a central computer. In the distributed LfD system presented here multiple trainers train multiple robots on different, but related, tasks in parallel and each robot runs its own on-board evolutionary algorithm. The robots share the training data, reducing the total time required for demonstrations, and exchange promising individuals as in typical island models. These experiments compare robotic performance on a task after distributing the behaviors or the simple demonstrations to performance using a non-distributed LfD model receiving complex demonstrations. Our results show a strong improvement to behavior when using distributed simple demonstrations. |

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.
