An evaluation of the bootstrap for model validation in mixture models

2017 · Communications in Statistics - Simulation and Computation

Bootstrapping has been used as a diagnostic tool for validating model results for a wide array of statistical models. Here we evaluate the use of the non-parametric bootstrap for model validation in mixture models. We …

MadSGM: Multivariate Anomaly Detection with Score-based Generative Models

2023 · arXiv (Cornell University)

The time-series anomaly detection is one of the most fundamental tasks for time-series. Unlike the time-series forecasting and classification, the time-series anomaly detection typically requires unsupervised (or self-supervised) training since collecting and labeling anomalous observations …

Privacy-Preserving Argumentative Explanations (Student Abstract)

2026 · Proceedings of the AAAI Conference on Artificial Intelligence

We propose a framework for privacy-preserving argumentative explanations using homomorphic encryption. This method applies the Cheon-Kim-Kim-Song scheme, along with a soft k-means adapted for encrypted computation, to generate explanations without exposing sensitive data. By leveraging …
