New CuBAS framework uses information geometry for adaptive data sampling

Researchers have developed CuBAS (Curvature-Based Adaptive Sampling), a novel framework for selecting informative data points for supervised classification tasks. This method leverages information geometry, viewing a labeled dataset as a statistical manifold where local curvature, derived from Fisher information, indicates data complexity. CuBAS constructs a k-nearest-neighbor graph and calculates curvature scores to identify regions of high and low geometric complexity, enabling the creation of compact yet informative training subsets. Empirical results across numerous benchmark datasets show CuBAS consistently outperforms random sampling and uncertainty-based methods, offering computational efficiency and theoretical grounding.
