New POSSE-kNN method improves binary classification accuracy

A new machine learning method called POSSE-kNN has been developed for binary classification tasks, particularly for tabular data. This ensemble technique combines bootstrap sampling, random feature subspaces, out-of-bag screening, and a novel pathwise selection of neighbors. Evaluations on ten benchmark datasets show POSSE-kNN achieving superior aggregate results in accuracy, Cohen's kappa, and Brier score compared to six established methods. AI

IMPACT Introduces a novel ensemble method that enhances performance on tabular data classification tasks.

    POSSE-kNN: Pathwise Out-of-Bag Selected Subspace Ensembles for Binary Classification

    arXiv:2211.11278v3 Announce Type: replace Abstract: Nearest neighbour classification is attractive for tabular data, but its performance can deteriorate when a fixed query centred neighbourhood does not follow the local class geometry. This study evaluates POSSE-$k$NN, a pathwise…
