What is it about?
The paper presents the Persistent Homology Classifier (PHC), a novel machine learning algorithm based on persistent homology, designed for classification tasks, including classification of image datasets like Fashion MNIST. By using topological features and their lifespans to classify data, PHC demonstrated competitive performance, outperforming algorithms like CART and RF while being comparable to KNN but underperforming compared to SVM and LDA. The research highlights PHC’s effectiveness in image classification, particularly showing improved accuracy as dataset size increases.
