Nemotron 3 Ultra: Open, Efficient Mixture-of-Experts Hybrid Mamba-Transformer Model for Agentic Reasoning
NVIDIA, :, Aaron Blakeman +572
We introduce Nemotron 3 Ultra, a 550 billion total and 55 billion active parameter Mixture-of-Experts Hybrid Mamba-Attention language model. We pre-trained Nemotron 3 Ultra on 20 t…
Sionna: An Open-Source Library for Next-Generation Physical Layer Research
Jakob Hoydis, Sebastian Cammerer, Fayçal Ait Aoudia +4
Sionna is a GPU-accelerated open-source library for link-level simulations based on TensorFlow. It enables the rapid prototyping of complex communication system architectures and p…
Sparse IDMA: A Joint Graph-Based Coding Scheme for Unsourced Random Access
Asit Pradhan, Vamsi Amalladinne, Avinash Vem +2
This article introduces a novel communication paradigm for the unsourced, uncoordinated Gaussian multiple access problem. The major components of the envisioned framework are as fo…
A Coded Compressed Sensing Scheme for Uncoordinated Multiple Access
Vamsi K. Amalladinne, Jean-Francois Chamberland, Krishna R. Narayanan
This article introduces a novel communication scheme, termed coded compressed sensing, for unsourced multiple-access communication. The proposed divide-and-conquer approach leverag…
A Coupled Compressive Sensing Scheme for Unsourced Multiple Access
Vamsi K. Amalladinne, Avinash Vem, Dileep Kumar Soma +2
This article introduces a novel paradigm for the unsourced multiple-access communication problem. This divide-and-conquer approach leverages recent advances in compressive sensing…
Sub-string/Pattern Matching in Sub-linear Time Using a Sparse Fourier Transform Approach
Nagaraj T. Janakiraman, Avinash Vem, Krishna R. Narayanan +1
We consider the problem of querying a string (or, a database) of length bits to determine all the locations where a substring (query) of length appears either exactly or is…
