Is Imitation All You Need? Generalized Decision-Making with Dual-Phase Training

ICCV 2023poster

We introduce DualMind, a generalist agent designed to tackle various decision-making tasks that addresses challenges posed by current methods, such as overfitting behaviors and dependence on task-specific fine-tuning. DualMind uses a novel "Dual-phase" training strategy that emulates how humans lear…

SMART: Self-supervised Multi-task pretrAining with contRol Transformers

ICLR 2023top-25%

Self-supervised pretraining has been extensively studied in language and vision domains, where a unified model can be easily adapted to various downstream tasks by pretraining representations without explicit labels. When it comes to sequential decision-making tasks, however, it is difficult to prop…

Learning Visuomotor Policies for Aerial Navigation Using Cross-Modal Representations

IROS 2020poster

Machines are a long way from robustly solving open-world perception-control tasks, such as first-person view (FPV) aerial navigation. While recent advances in end-to- end Machine Learning, especially Imitation Learning and Reinforcement appear promising, they are constrained by the need of large amo…

DROAN - Disparity-Space Representation for Obstacle Avoidance: Enabling Wire Mapping & Avoidance

IROS 2018poster

Wire detection, depth estimation and avoidance is one of the hardest challenges towards the ubiquitous presence of robust autonomous aerial vehicles. We present an approach and a system which tackles these three challenges along with generic obstacle avoidance as well. First, we perform monocular wi…

Wire detection using synthetic data and dilated convolutional networks for unmanned aerial vehicles

IROS 2017poster

Wire detection is a key capability for safe navigation of autonomous aerial vehicles and is a challenging problem as wires are generally only a few pixels wide, can appear at any orientation and location, and are hard to distinguish from other similar looking lines and edges. We leverage the recent…
