IAPR Technical Committee 2 (TC2)

The IAPR TC2 on Structural and Syntactical Pattern Recognition is one of the official Technical Committees of the International Association for Pattern Recognition. The aim of the TC2 is to promote interaction and collaboration among researchers working on Structural and Syntactical Pattern Recognition (SSPR).

Since 1996, the IAPR TC1 and TC2 jointly organise the biennial conference S+SSPR. The event is traditionally colocated with the International Conference on Pattern Recognition (ICPR), attracting participants working in a wide variety of fields that make use of statistical, structural or syntactic pattern recognition techniques.

S+SSPR 2026

S+SSPR is a well-established forum bringing together researchers working on statistical, structural, and syntactic approaches to pattern recognition, as well as their applications. The workshop will take place shortly after ICPR 2026 and will be hosted by the University of Bern, Switzerland.

Topics include, but are not limited to:

Statistical Pattern Recognition (SPR)

Classification, prediction, Gaussian processes; Feature selection, ensemble methods, dimensionality reduction; Metric and representation learning; Semi- and weakly supervised learning; Active learning, novelty detection; Deep, generative, and adversarial models; Reinforcement learning, transfer learning, domain adaptation; Clustering and data modeling

Structural and Syntactic Pattern Recognition (SSPR)

Graph-based methods; Graph neural networks; Structural matching and complexity; Graphical models and structural kernels; Spectral methods; Spatio-temporal pattern analysis; Shape analysis and document understanding; Multimedia retrieval and intelligent sensing
