Predicting Terrorist Attacks in the United States using Localized News Data

no code implementations12 Jan 2022 Steven J. Krieg, Christian W. Smith, Rusha Chatterjee, Nitesh V. Chawla

From a machine learning perspective, we found that the Random Forest model outperformed several deep models on our multimodal, noisy, and imbalanced data set, thus demonstrating the efficacy of our novel feature representation method in such a context.

A data-driven approach to sampling matrix selection for compressive sensing

no code implementations20 Jun 2019 Elin Farnell, Henry Kvinge, John P. Dixon, Julia R. Dupuis, Michael Kirby, Chris Peterson, Elizabeth C. Schundler, Christian W. Smith

We propose a method for defining an order for a sampling basis that is optimal with respect to capturing variance in data, thus allowing for meaningful sensing at any desired level of compression.
