IWANN2023 - Special Session on "Ordinal Classification"

IWANN2023 Azores

Scope

Ordinal classification is a recent area including those classification tasks in which exist a natural order between the labels, i. e. the target variable presents an ordering relation. For instance, most of health-related problems are covered by this area, since the different stages of a disease could be categorized by {“initial”, “mild”, “medium”, “severe”, “deep”}. In this way, ordinal classification techniques consider the natural order among the classes and penalize regarding the magnitude of the errors. Specific solutions have been recently proposed in the machine learning and pattern recognition literature, resulting in a very promising field. Moreover, it is also a hot topic in the deep learning field, where several approaches have been presented to the literature.

This special session aims to cover a wide range of works and recent advances on ordinal classification. We hope that this session can provide a common forum for researchers and practitioners to exchange their ideas and report their latest finding in the area.

Topics

In particular we encourage submissions addressing the following issues:

  • Extensions of standard classification methods to ordinal classification (support vector machines, Gaussian processes, discriminant analysis, etc).
  • Extensions of deep learning techniques to ordinal classification.
  • Threshold models and decomposition methods for ordinal classification.
  • Pre-processing methods for ordinal data (data cleaning techniques, feature selection, over-sampling, under-sampling, etc.).
  • Evaluation measures for ordinal classification.
  • Data preprocessing (feature selection, noise filtering, etc.) for ordinal classification.
  • Development of novel ordinal classification frameworks.
  • Time series ordinal classification (extensions of standard time series classification methods to time series ordinal classification).
  • Applications in 4.0 industry, bio-medicine, renewable energies and environmental issues, economy… and any other real-world problems.
