Instance based kNN modification for classification of medical data

Orczyk T., Porwik P., Lewandowski M., Cholewa M.

Journal of Medical Informatics & Technologies

2015

Vol. 24

99--106

Paper describes a novel modification to a well known kNN algorithm, which enables using it for medical data, which often is a class-imbalanced data with randomly missing values. Paper presents the modified algorithm details, experiment setup, results obtained on a cross validated classification of a benchmark database with randomly removed values (missing data) and records (class imbalance), and their comparison with results of the state of the art classification algorithms.
