A Provably Accurate Randomized Sampling Algorithm for Logistic Regression

1 code implementation26 Feb 2024 Agniva Chowdhury, Pradeep Ramuhalli

When the number of observations greatly exceeds the number of predictor variables, we present a simple, randomized sampling-based algorithm for logistic regression problem that guarantees high-quality approximations to both the estimated probabilities and the overall discrepancy of the model.

Robust Errant Beam Prognostics with Conditional Modeling for Particle Accelerators

no code implementations22 Nov 2023 Kishansingh Rajput, Malachi Schram, Willem Blokland, Yasir Alanazi, Pradeep Ramuhalli, Alexander Zhukov, Charles Peters, Ricardo Vilalta

To avoid these faults, we apply anomaly detection techniques to predict any unusual behavior and perform preemptive actions to improve the total availability of particle accelerators.

Fault Prognosis in Particle Accelerator Power Electronics Using Ensemble Learning

no code implementations30 Sep 2022 Majdi I. Radaideh, Chris Pappas, Mark Wezensky, Pradeep Ramuhalli, Sarah Cousineau

Early fault detection and fault prognosis are crucial to ensure efficient and safe operations of complex engineering systems such as the Spallation Neutron Source (SNS) and its power electronics (high voltage converter modulators).
