Robustness of class-based path-vector systems

A.D. Jaggard, V. Ramachandran
Proceedings of the 12th IEEE International Conference on Network Protocols, 2004. ICNP 2004.  
The robustness of these class-based path-vector systems depends on the presence of a global constraint on the system, but an adequate constraint has not yet been given in general.  ...  In this paper, we provide the best known robustness constraint for class-based systems.  ...  The class-based path-vector routing protocol will work as expected as long as the system has been designed to prevent bad policy interactions.  ...

BLSTM Neural Network Based Word Retrieval for Hindi Documents

Raman Jain, Volkmar Frinken, C.V. Jawahar, R. Manmatha
2011 2011 International Conference on Document Analysis and Recognition  
For these reasons, robust OCRs are non existent for Hindi. Therefore, Hindi document repositories are not amenable to indexing and retrieval.  ...  Our scalable retrieval scheme avoids explicit recognition of characters.  ...  The Devanagari script for writing Hindi requires as many as 800 classes for recognition [4] and therefore a large amount of training data is required to build a robust recognition system.  ...
