Abstract: Firefighters still rely on coarse remote sensing and inaccurate eyewitness reports to localize spreading wildfires. Despite advances in sensing, UAVs, and computer vision, the community has yet to combine the right modalities to achieve effective wildfire geolocalization and spotting. We present FireLoc, a fast and accurate wildfire crowdsensing system that localizes and maps wildfires combining ground cameras and landscape data. Prior image-based localization techniques fail in vegetated areas as they are tuned for close-range human-built environments. Instead, FireLoc integrates monocular depth mapping models, topography models, and cross-camera methods to achieve over 1000m range in vegetated environments leveraging low-cost smartphones. Due to the paucity of historical wildfire data, we built a wildfire simulator to provide additional data for validation. We show that FireLoc surpasses prior wildfire mapping work and reduces wildfire mapping time from hours to seconds.In future work, we propose a complete system that ensures landscape monitoring beyond the early wildfire propagation phase. We then emphasize multimodal approaches to landscape understanding for adaptive fuel analysis. Beyond monitoring the wildfire expansion, future systems can structurally understand the shifting landscape.Location: Henry Salvatori Computer Science Center (SAL) - 300

Presentation Title: Decision Making in Complex Action Spaces

Abstract: The action space of a reinforcement learning agent defines how it interacts with the world, whether selecting discrete items in a recommender system or controlling continuous movements in robotics. An agent is considered optimal when, at every step, it chooses an action within its action space that maximizes the expected future return. In this thesis, I study the relationship between expected returns and action space, identifying three key complexities that make certain tasks challenging. Specifically, I address decision-making in (1) unseen actions, such as new items to recommend; (2) changing action spaces, like variable inventory or toolset; and (3) locally optimal actions that hinder the search for the global best action. For each, we propose solutions to enhance agent adaptability and decision-making across complex action spaces.
