| Abstract | Sparse measurement structures - in which each measurement only depends on a small number of the inputs - arise in models of many problems such as sensor networks, group testing and even lossless data compression. The most important question in these applications is ‘How many measurements are sufficient to reconstruct the input ?’. Regular structures, where each input is measured the same number of times, require fewer measurements than when arbitrary measurements are used. In this paper we conduct a general analysis of the performance of these regular measurement structures when used for lossy reconstruction of the input in the presence of measurement noise. The main contribution of our work is the generality of the result which is applicable to lossy detection with arbitrary, even non-linear measurements and with inputs and outputs in any discrete domain. The second contribution is the quantification of the effect of noise in the measurements on the reconstruction performance, which can be used to analyze the robustness of these sparse measurement structures. We show the generality and applicability of our results by analyzing the performance of pooling designs for rare allele detection. |

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.
