One-shot Imitation Learning via Interaction Warping
Ondrej Biza, Skye Thompson, Kishore Reddy Pagidi +7
Imitation learning of robot policies from few demonstrations is crucial in open-ended applications. We propose a new method, Interaction Warping, for learning SE(3) robotic manipul…
Interlayer excitons in semiconductor bilayers under a strong electric field
S. Kovalchuk, K. Greben, A. Kumar +7
Excitons in bilayer transition metal dichalcogenides (2L-TMDs) are Coulomb-bound electron/hole pairs that can be viewed as broadly tunable analogs of atomic or molecular systems. H…
Reference Resolution and Context Change in Multimodal Situated Dialogue for Exploring Data Visualizations
Abhinav Kumar, Barbara Di Eugenio, Abari Bhattacharya +2
Reference resolution, which aims to identify entities being referred to by a speaker, is more complex in real world settings: new referents may be created by processes the agents e…
Topological polarization networking in uniaxial ferroelectrics
Y. Tikhonov, J. R. Maguire, C. J. McCluskey +8
Discovery of topological polarization textures has put ferroelectrics at the frontier of topological matter science. High-symmetry ferroelectric oxide materials allowing for freedo…
Adaptive Multi-User Clustering and Power Allocation for NOMA Systems with Imperfect SIC
Nemalidinne Siva Mouni, Pavan Reddy M., Abhinav Kumar +1
Non-orthogonal multiple access (NOMA) is recognized as a promising radio access technique for the next generation wireless systems. We consider a practical downlink NOMA system wit…
-Fairness User Pairing for Downlink NOMA Systems with Imperfect Successive Interference Cancellation
Nemalidinne Siva Mouni, Pavan Reddy M., Abhinav Kumar +1
Non-orthogonal multiple access (NOMA) is considered as one of the predominant multiple access technique for the next-generation cellular networks. We consider a 2-user pair downlin…
Spectral and Energy Efficient User Pairing for RIS-assisted Uplink NOMA Systems with Imperfect Phase Compensation
Kusuma Priya P., Pavan Reddy M., Abhinav Kumar
Non-orthogonal multiple access (NOMA) is considered a key technology for improving the spectral efficiency of fifth-generation (5G) and beyond 5G cellular networks. NOMA is benefic…
Location reference identification from tweets during emergencies: A deep learning approach
Abhinav Kumar, Jyoti Prakash Singh
Twitter is recently being used during crises to communicate with officials and provide rescue and relief operation in real time. The geographical location information of the event,…
Parametric Synthesis of Text on Stylized Backgrounds using PGGANs
Mayank Gupta, Abhinav Kumar, Sriganesh Madhvanath
We describe a novel method of generating high-resolution real-world images of text where the style and textual content of the images are described parametrically. Our method combin…
Streaming Video QoE Modeling and Prediction: A Long Short-Term Memory Approach
Nagabhushan Eswara, S Ashique, Anand Panchbhai +5
HTTP based adaptive video streaming has become a popular choice of streaming due to the reliable transmission and the flexibility offered to adapt to varying network conditions. Ho…
Modeling Continuous Video QoE Evolution: A State Space Approach
Nagabhushan Eswara, Hemanth P. Sethuram, Soumen Chakraborty +3
A rapid increase in the video traffic together with an increasing demand for higher quality videos has put a significant load on content delivery networks in the recent years. Due…
Neural Signatures for Licence Plate Re-identification
Abhinav Kumar, Shantanu Gupta, Vladimir Kozitsky +1
The problem of vehicle licence plate re-identification is generally considered as a one-shot image retrieval problem. The objective of this task is to learn a feature representatio…
Estimation of Bandlimited Grayscale Images From the Single Bit Observations of Pixels Affected by Additive Gaussian Noise
Abhinav Kumar, Animesh Kumar
The estimation of grayscale images using their single-bit zero mean Gaussian noise-affected pixels is presented in this paper. The images are assumed to be bandlimited in the Fouri…
Resource Allocation for CoMP in Cellular Networks with Base Station Switching
Yoghitha Ramamoorthi, Abhinav Kumar
Base station switching (BSS) can results in significant reduction in energy consumption of cellular networks during low traffic conditions. We show that the coverage loss due to BS…
Using Elimination Theory to construct Rigid Matrices
Abhinav Kumar, Satyanarayana V. Lokam, Vijay M. Patankar +1
The rigidity of a matrix A for target rank r is the minimum number of entries of A that must be changed to ensure that the rank of the altered matrix is at most r. Since its introd…
The D_4 root system is not universally optimal
Henry Cohn, John H. Conway, Noam D. Elkies +1
We prove that the D_4 root system (equivalently, the set of vertices of the regular 24-cell) is not a universally optimal spherical code. We further conjecture that there is no uni…
