| Abstract | Many studies have been performed to train a classification network using supervised learning. In order to enable a recognition network to learn autonomously or to later improve its recognition performance through simpler confirmation or rejection, it is desirable to model networks that have an intrinsic motivation system. Although reinforcement learning has been extensively studied, much of the existing models are symbolic whose internal nodes have preset meanings from a set of handpicked symbolic set that is specific for a given task or domain. Neural networks have been used to automatically generate internal (distributed) representations. However, modeling a neuromorphic motivational system for neural networks is still a great challenge. By neuromorphic, we mean that the motivational system for a neural network must be also a neural network, using a standard type of neuronal computation and neuronal learning. This work proposes a neuromorphic motivational system, which includes two subsystems — the serotonin system and the dopamine system. The former signals a large class of stimuli that are intrinsically aversive (e.g., stress or pain). The latter signals a large class of stimuli that are intrinsically appetitive (e.g., sweet and pleasure). We experimented with this motivational system for visual recognition settings to investigate how such a system can learn through interactions with a teacher, who does not give answers, but only punishments and rewards. |

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.
