There is more to graphs than meets the eye: Learning universal features with self-supervision

no code implementations31 May 2023 Laya Das, Sai Munikoti, Mahantesh Halappanavar

We hypothesize that leveraging multiple graphs of the same type/class can improve the quality of learnt representations in the model by extracting features that are universal to the class of graphs.

Uncertainty-aware deep learning for digital twin-driven monitoring: Application to fault detection in power lines

no code implementations20 Mar 2023 Laya Das, Blazhe Gjorgiev, Giovanni Sansavini

In such a scenario, the performance of the DNN model will be influenced by the uncertainty in the physics-based model as well as the parameters of the DNN.

Object detection-based inspection of power line insulators: Incipient fault detection in the low data-regime

no code implementations21 Dec 2022 Laya Das, Mohammad Hossein Saadat, Blazhe Gjorgiev, Etienne Auger, Giovanni Sansavini

We curate a large reference dataset of insulator images that can be used to learn robust features for detecting healthy and faulty insulators.

Scalable Graph Neural Network-based framework for identifying critical nodes and links in Complex Networks

no code implementations26 Dec 2020 Sai Munikoti, Laya Das, Balasubramaniam Natarajan

To overcome these challenges, this article proposes a scalable and generic graph neural network (GNN) based framework for identifying critical nodes/links in large complex networks.

Bayesian Graph Neural Network for Fast identification of critical nodes in Uncertain Complex Networks

no code implementations26 Dec 2020 Sai Munikoti, Laya Das, Balasubramaniam Natarajan

Most existing methods of critical node identification are based on an iterative approach that explores each node/link of a graph.
