  • Interval Fisher’s Discriminant Analysis and Visualisation

    Interval Fisher’s Discriminant Analysis and Visualisation arXiv:2512.11945v1 Announce Type: new Abstract: In Data Science, entities are typically represented by single valued measurements. Symbolic Data Analysis extends this framework to more complex structures, such as intervals and histograms, that express internal variability. We propose an extension of multiclass Fisher’s Discriminant Analysis to interval-valued data, using Moore’s…

  • Any-Step Density Ratio Estimation via Interval-Annealed Secant Alignment

    Any-Step Density Ratio Estimation via Interval-Annealed Secant Alignment arXiv:2509.04852v1 Announce Type: new Abstract: Estimating density ratios is a fundamental problem in machine learning, but existing methods often trade off accuracy for efficiency. We propose textit{Interval-annealed Secant Alignment Density Ratio Estimation (ISA-DRE)}, a framework that enables accurate, any-step estimation without numerical integration. Instead of modeling infinitesimal…

  • Adapted Prediction Intervals by Means of Conformal Predictions and a Custom Non-Conformity Score

    Adapted Prediction Intervals by Means of Conformal Predictions and a Custom Non-Conformity Score How confident should I be in a machine learning model’s prediction for a new data point? Could I get a range of likely values? Image by author When working on a supervised task, machine learning models can be used to predict the outcome for…
