| Abstract | Large heterogeneous teams will often be in situations where sensor data that is uncertain and conflicting is shared across a peer-to-peer network. Not every team member will have direct access to sensors and team members will be influenced mostly by teammates with whom they communicate directly. Simple models of a large team sharing beliefs to reach conclusions about the world show that the dynamics of such belief sharing systems are characterized by information cascades. These are ripples of belief changes through the system caused by a single additional sensor reading. Glinton et al. showed that such a system will exhibit qualitatively different dynamics sensitive to ranges over system parameters. In addition they showed that In one particular range, the system exhibits behavior known as scale-invariant dynamics which was found empirically to correspond to dramatically more accurate conclusions being reached by team members. In this paper we provide an analytical explanation for the performance of scale invariant dynamics by leveraging signal processing concepts. We show that scale invariant dynamics behave as an adaptive information filter with a response that automatically adjusts to the accuracy of sensor inputs. This adaptation causes the performance gain. |

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.
