Sequence to Sequence Learning for Optical Character Recognition
Devendra Kumar Sahu, Mohak Sukhwani
We propose an end-to-end recurrent encoder-decoder based sequence learning approach for printed text Optical Character Recognition (OCR). In contrast to present day existing state-…
Multistage SFM: A Coarse-to-Fine Approach for 3D Reconstruction
Rajvi Shah, Aditya Deshpande, P J Narayanan
Several methods have been proposed for large-scale 3D reconstruction from large, unorganized image collections. A large reconstruction problem is typically divided into multiple co…
Complementarity between Tripartite Quantum Correlation and Bipartite Bell Inequality Violation in Three Qubit States
Palash Pandya, Avijit Misra, Indranil Chakrabarty
We find a single parameter family of genuinely entangled three qubit pure states, called the maximally Bell inequality violating states (MBV), which exhibit maximum Bell inequality…
Quantum no-go theorems in causality respecting systems in presence of closed timelike curves: Tweaking the Deutsch condition
Asutosh Kumar, Indranil Chakrabarty, Arun Kumar Pati +2
We consider causality respecting (CR) quantum systems interacting with closed timelike curves (CTCs), within the Deutsch model. We introduce the concepts of popping up and eliminat…
Diverse Yet Efficient Retrieval using Hash Functions
Vidyadhar Rao, Prateek Jain, C. V Jawahar
Typical retrieval systems have three requirements: a) Accurate retrieval i.e., the method should have high precision, b) Diverse retrieval, i.e., the obtained set of points should…
Significance of Maximum Spectral Amplitude in Sub-bands for Spectral Envelope Estimation and Its Application to Statistical Parametric Speech Synthesis
Sivanand Achanta, Anandaswarup Vadapalli, Sai Krishna R. +1
In this paper we propose a technique for spectral envelope estimation using maximum values in the sub-bands of Fourier magnitude spectrum (MSASB). Most other methods in the literat…
Non-relativistic matter and Dark energy in a quantum conformal model
Pankaj Jain, Gopal Kashyap, Subhadip Mitra
We consider a generalization of the standard model which respects quantum conformal invariance. This model leads to identically zero vacuum energy. We show how non-relativistic mat…
Does normal pupil diameter differences in population underlie the color selection of the #dress?
Kavita Vemuri, Kulvinder Bisla, SaiKrishna Mulpuru +1
The fundamental question that arises from the color composition of the #dress is: 'What are the phenomena that underlie the individual differences in colors reported given all othe…
Machine Learning Based Cooperative Relay Selection in Virtual MIMO
Kunal Sankhe, Chandan Pradhan, Sumit Kumar +1
In cellular systems, virtual multiple-input multiple-output (V-MIMO) technology promises to achieve performance gains comparable to conventional MIMO. In this paper, we propose coo…
Pair Production of Scalar Leptoquarks at the LHC to NLO Parton Shower Accuracy
Tanumoy Mandal, Subhadip Mitra, Satyajit Seth
We present the scalar leptoquark pair production process at the LHC computed at the next-to-leading order in QCD, matched to the PYTHIA parton shower using the MC@NLO formalism. We…
Dynamic Grover Search: Applications in Recommendation systems and Optimization problems
Indranil Chakrabarty, Shahzor Khan, Vanshdeep Singh
In the recent years, we have seen that Grover search algorithm (Proceedings, 28th annual ACM symposium on the theory of computing, pp. 212-219, 1996) by using quantum parallelism h…
Calculation of molecular free energies in classical potentials
Asaf Farhi
Free energies of molecules can be calculated by quantum computations or by normal mode classical calculations. However, the first can be computationally impractical for large molec…
An Optimal Bidimensional Multi-Armed Bandit Auction for Multi-unit Procurement
Satyanath Bhat, Shweta Jain, Sujit Gujar +1
We study the problem of a buyer (aka auctioneer) who gains stochastic rewards by procuring multiple units of a service or item from a pool of heterogeneous strategic agents. The re…
Local, nonlocal quantumness and information theoretic measures
Pankaj Agrawal, Sk Sazim, Indranil Chakrabarty +1
It has been suggested that there may exist quantum correlations that go beyond entanglement. The existence of such correlations can be revealed by quantum discord, but not by the c…
Towards Deep Semantic Analysis Of Hashtags
Piyush Bansal, Romil Bansal, Vasudeva Varma
Hashtags are semantico-syntactic constructs used across various social networking and microblogging platforms to enable users to start a topic specific discussion or classify a pos…
