We are excited to announce that 15th IAPR-TC15 International Workshop on Graph-Based Representations in Pattern Recognition will be hosted from 9 to 11 June 2025 in Pisa (Italy).

GbR is a biennial workshop organized by the 15th Technical Committee. This workshop series traditionally provides a forum for presenting and discussing research results and applications in the intersection of pattern recognition, image analysis on one side and graph theory on the other side.

Additionally, new emerging topics and approaches in graph representation learning and graph neural networks are becoming relevant in pattern recognition; researchers in this field are encouraged to actively participate. Furthermore, the application of graphs to pattern recognition problems in other fields like computational topology, graphic recognition systems, bioinformatics, cybersecurity and engineering is also highly welcome at the workshop.

The scope of GbR2027 includes, but is not limited to, the following topics:

  • Graph-based Pattern Recognition
    • Graph learning, clustering, matching, and classification
    • Graph similarity, distances, kernels, embeddings
    • Graph signal processing and spectral methods
    • Graph-based representations (images, shapes) and segmentation
    • Statistical, probabilistic, and algorithmic graph theory
    • Graph algorithms, combinatorial & geometric optimization
    • Geometry processing and manifold learning
  • Deep Learning on Graphs
    • Graph Neural Networks (architectures, expressivity, transformers, equivariance)
    • Scalable, self-supervised, and foundation graph models
    • Graph generative models (diffusion, flow, etc.)
    • Robust, trustworthy, and fair graph ML (explainability, adversarial, privacy)
    • Causal inference and reasoning on graphs
  • Applications
    • Life sciences and medicine (bioinformatics, chemistry, health)
    • Social and network analysis
    • NLP, LLMs, and knowledge graphs
    • Computer vision and geometric ML
    • Recommender systems, security, physical sciences
    • Data mining and general graph-based applications
    • Benchmarks, datasets, libraries, and infrastructures

The proceedings of the workshop will be published in the LNCS series, and we are currently in discussions with Pattern Recognition Letters to create a special issue related to GbR topics following the workshop.
