Deep Graph Unfolding for Beamforming in MU-MIMO Interference Networks

1 code implementation2 Apr 2023 Arindam Chowdhury, Gunjan Verma, Ananthram Swami, Santiago Segarra

We develop an efficient and near-optimal solution for beamforming in multi-user multiple-input-multiple-output single-hop wireless ad-hoc interference networks.

Stability Analysis of Unfolded WMMSE for Power Allocation

1 code implementation14 Oct 2021 Arindam Chowdhury, Fernando Gama, Santiago Segarra

Power allocation is one of the fundamental problems in wireless networks and a wide variety of algorithms address this problem from different perspectives.

Label Propagation across Graphs: Node Classification using Graph Neural Tangent Kernels

no code implementations7 Oct 2021 Artun Bayer, Arindam Chowdhury, Santiago Segarra

In this context, our current work considers a challenging inductive setting where a set of labeled graphs are available for training while the unlabeled target graph is completely separate, i. e., there are no connections between labeled and unlabeled nodes.

GIST: Distributed Training for Large-Scale Graph Convolutional Networks

1 code implementation20 Feb 2021 Cameron R. Wolfe, Jingkang Yang, Arindam Chowdhury, Chen Dun, Artun Bayer, Santiago Segarra, Anastasios Kyrillidis

The graph convolutional network (GCN) is a go-to solution for machine learning on graphs, but its training is notoriously difficult to scale both in terms of graph size and the number of model parameters.

Unfolding WMMSE using Graph Neural Networks for Efficient Power Allocation

1 code implementation22 Sep 2020 Arindam Chowdhury, Gunjan Verma, Chirag Rao, Ananthram Swami, Santiago Segarra

We study the problem of optimal power allocation in a single-hop ad hoc wireless network.

ChartNet: Visual Reasoning over Statistical Charts using MAC-Networks

no code implementations21 Nov 2019 Monika Sharma, Shikha Gupta, Arindam Chowdhury, Lovekesh Vig

To this end, we formulate the problem of reasoning over statistical charts as a classification task using MAC-Networks to give answers from a predefined vocabulary of generic answers.

Deep Reader: Information extraction from Document images via relation extraction and Natural Language

no code implementations11 Dec 2018 Vishwanath D, Rohit Rahul, Gunjan Sehgal, Swati, Arindam Chowdhury, Monika Sharma, Lovekesh Vig, Gautam Shroff, Ashwin Srinivasan

In this paper, we propose a novel enterprise based end-to-end framework called DeepReader which facilitates information extraction from document images via identification of visual entities and populating a meta relational model across different entities in the document image.
