Dirichlet Process-Based Robust Clustering Using the Median-of-Means Estimator

IJCAI 2025

Clustering stands as one of the most prominent challenges in unsupervised machine learning. Among centroid-based methods, the classic $k$-means algorithm, based on Lloyd's heuristic, is widely used. Nonetheless, it is a well-known fact that $k$-means and its variants face several challenges, includi

On Some Fast And Robust Classifiers For High Dimension, Low Sample Size Data

AISTATS 2022poster

In high dimension, low sample size (HDLSS) settings, distance concentration phenomena affects the performance of several popular classifiers which are based on Euclidean distances. The behaviour of these classifiers in high dimensions is completely governed by the first and second order moments of t…
