Online stability in the low-resolution, real-geography setting is reproducibly achievable across diverse architectures, and offline and online zonal mean biases are near-identical across architectures.

We show that long sequence models are sensitive to the order of patches provided to them, affecting performance by as much as 13%. We propose REOrder, an information-theoretic and RL-based approach to learning an optimal patch ordering to improve performance.

Can LLMs accurately represent probabilities? We find in this work, no! By using biased coin flips as a simple but powerful exemplar, we show that in-context learning can be used to induce semi-accurate probability simulation in LLMs.

China is training machine learning models to target American and Allied navel vessels, but how well do they work? In this paper, we train a state-of-the-art machine learning model on a leaked Chinese dataset that labels Aegis combat system components on military vessels. We propose a new methodology for open source assessment of adversary AI capabilities.

Current US AI hardware export controls are based on the best AI accelerator chip available at that time. This presents wide loopholes which allow adversarial nations to still maintain their capabilities. We propose an alternate way to set export control thresholds based on the analysis of specific ML workloads.
