    Enhancing Expressive Power Of Graph Neural Networks Using Geometric Transformations
    (Indian Statistical Institute, Kolkata, 2025-06) Dey, Suranjan
    Graph Neural Networks (GNNs) are highly effective in many real-world tasks, such as molecular property prediction, modeling protein structures, analyzing user-item relationships, and making link predictions. What sets them apart is their ability to learn meaningful representations by capturing not just the features of individual nodes, but also the overall structure of the graph they belong to. This expressive strength allows GNNs to model complex relationships more accurately. In this work, we take a step further by introducing geometric transformations aimed at improving how GNNs handle spatial information. In particular, we focus on angular aggregation methods that maintain rotational consistency, helping the model deliver more stable and reliable predictions even when the input orientation changes
