GRASP: Accelerating Shortest Path Attacks via Graph Attention

no code implementations12 Oct 2023 Zohair Shafi, Benjamin A. Miller, Ayan Chatterjee, Tina Eliassi-Rad, Rajmonda S. Caceres

We consider an APX-hard problem, where an adversary aims to attack shortest paths in a graph by removing the minimum number of edges.

Disentangling Node Attributes from Graph Topology for Improved Generalizability in Link Prediction

1 code implementation17 Jul 2023 Ayan Chatterjee, Robin Walters, Giulia Menichetti, Tina Eliassi-Rad

Our proposed method, UPNA (Unsupervised Pre-training of Node Attributes), solves the inductive link prediction problem by learning a function that takes a pair of node attributes and predicts the probability of an edge, as opposed to Graph Neural Networks (GNN), which can be prone to topological shortcuts in graphs with power-law degree distribution.

Quality Assurance in MLOps Setting: An Industrial Perspective

no code implementations23 Nov 2022 Ayan Chatterjee, Bestoun S. Ahmed, Erik Hallin, Anton Engman

The increased use of automated ML software engineering practices in industries such as manufacturing and utilities requires an automated Quality Assurance (QA) approach as an integral part of ML software.

Gravitationally collapsing stars in $f(R)$ gravity
