This program funds projects that use AI to improve probabilistic forecasting and support sound decision-making. We aim to support the creation of AI models that enhance forecasting accuracy, tools that help with tasks relevant to clear reasoning, and research to understand when models do and do not support truth-oriented reasoning.
