GOMAA-Geo: GOal Modality Agnostic Active Geo-localization

NeurIPS 2024poster

We consider the task of active geo-localization (AGL) in which an agent uses a sequence of visual cues observed during aerial navigation to find a target specified through multiple possible modalities. This could emulate a UAV involved in a search-and-rescue operation navigating through an area, obs…

Embodied Visual Active Learning for Semantic Segmentation

AAAI 2021technical

We study the task of embodied visual active learning, where an agent is set to explore a 3d environment with the goal to acquire visual scene understanding by actively selecting views for which to request annotation. While accurate on some benchmarks, today's deep visual recognition pipelines tend t…

Generating Scenarios with Diverse Pedestrian Behaviors for Autonomous Vehicle Testing

CoRL 2021poster

There exist several datasets for developing self-driving car methodologies. Manually collected datasets impose inherent limitations on the variability of test cases and it is particularly difficult to acquire challenging scenarios, e.g. ones involving collisions with pedestrians. A way to alleviate…

Domes to Drones: Self-Supervised Active Triangulation for 3D Human Pose Reconstruction

NeurIPS 2019poster

Existing state-of-the-art estimation systems can detect 2d poses of multiple people in images quite reliably. In contrast, 3d pose estimation from a single image is ill-posed due to occlusion and depth ambiguities. Assuming access to multiple cameras, or given an active system able to position itsel…

Deep Reinforcement Learning of Region Proposal Networks for Object Detection

CVPR 2018poster

We propose drl-RPN, a deep reinforcement learning-based visual recognition model consisting of a sequential region proposal network (RPN) and an object detector. In contrast to typical RPNs, where candidate object regions (RoIs) are selected greedily via class-agnostic NMS, drl-RPN optimizes an obje…
