Learning from Animal and Human Videos
Abstract: Animals and humans can learn from the billions of years of life on Earth and the evoluNon that has shaped it. If robots can borrow from that wealth of experience, they too could be enabled to learn from the experience, instead of learning through brute force trial-and-error. Learning from internet-scale videos, such as the […]

Reconstructing Tree Skeletons in Agricultural Robotics: A Comparative Study of Single-View and Volumetric Methods
Abstract: This thesis investigates the problem of reconstructing tree skeletons for agricultural robotics, comparing single-view image-based (Image to 3D) and volumetric (3D to 3D) methods. Accurate 3D modeling is essential for robotic tasks like pruning and harvesting, where understanding the underlying branch structure is critical. Using a custom-generated dataset of synthetic trees, we train encoder-decoder […]

Acoustic Neural 3D Reconstruction Under Pose Drift
Abstract: We consider the problem of optimizing neural implicit surfaces for 3D reconstruction using acoustic images collected with drifting sensor poses. The accuracy of current state-of-the-art 3D acoustic modeling algorithms is highly dependent on accurate pose estimation; small errors in sensor pose can lead to severe reconstruction artifacts. In this paper, we propose an algorithm […]

Towards Natural Language-Driven Shape Arrangement Synthesis using Semantically-Aware Geometric Constraints
Abstract: While diffusion-based models excel at generating photorealistic images from text, a more nuanced challenge emerges when constrained to using only a fixed set of rigid shapes—akin to solving tangram puzzles or arranging real-world objects to match semantic descriptions. We formalize this problem as shape-based image generation, a new natural language-guided image-to-image translation task that […]

Enhancing Reinforcement Learning with Error-Prone Language Models
The correct specification of reward models is a well-known challenge in reinforcement learning. Hand-crafted reward functions, which are usually sparse, often lead to inefficient or suboptimal policies, misalignment with user values, or difficulties in attributing credit or blame within multi-agent systems. Reinforcement learning from human feedback is a successful technique that can mitigate such issues [...]

Foundation Control Model for General Embodied Intelligence
Abstract: With the growing accessibility of humanoid hardware and rapid advances in foundation models, we are entering an era where achieving general embodied intelligence is within reach—enabling humanoid robots to perform a wide range of tasks in human-centric environments. Despite significant progress in language and vision foundation models, controlling humanoids with high degrees of freedom [...]

Learning Humanoid Robots from Simulation to Real to Simulation
Abstract: How do we teach humanoid robots to move like humans—and do so reliably in the real world? In this talk, I’ll share my journey in building a learning-based pipeline that closes the loop between simulation and reality for humanoid whole-body control. Starting from real-time teleoperation (H2O), to scalable data humanoid collection (OmniH2O), to learning [...]

Experience-Based Action Advising for Multi-Agent Teaming
Abstract: We study how to improve coordination efficiency for multi-agent teams with heterogeneously experienced agents. In such a setting, experienced agents can transfer their knowledge to less experienced agents to accelerate their learning, while leveraging the students' initial expertise to inform what knowledge to transfer. Inspired by this idea, this work specifically assumes one teacher [...]

Towards Controllable Sampling and Diverse Score Distillation in Diffusion Models
Abstract: Denoising diffusion models have emerged as a powerful paradigm for generative modeling, which has been widely used for perception, generation, and action. These models can be utilized through sampling or score distillation; however, existing methods lack controllability in sampling and suffer from limited diversity in score distillation. In this thesis, we propose two complementary mechanisms to enhance the [...]

RESCUE Rollers: A Platform for Collaborative, Multi-robot Exploration in Search and Rescue
Abstract: The use of robotic platforms for search and rescue remains a significant challenge for many roboticist. While human and animal first responders play critical roles, their effectiveness can be limited by biological constraints. Robotic systems offer the potential to overcome these limitations, especially in environments inaccessible to humans and animals due to size or [...]

Generative 3D Garment Modeling with Sparse Visual Cues
Abstract: As digital apparel becomes increasingly vital to virtual environments and personalized experiences, there is a growing need for intuitive tools that enable non-experts to create and interact with 3D garments. To broaden accessibility, these tools must function effectively with minimal input - raising the key question: How can we achieve high-quality 3D garment modeling [...]

Towards Efficient and Accurate Neural Geometry and Appearance Representations
Abstract: Neural scene representations have transformed the way we model and understand the visual world, enabling stunningly realistic reconstructions from image data. However, these advances often come at a significant computational cost, particularly due to the inefficiencies in volume rendering. In this talk, I’ll present GL-NeRF, a new approach that tackles this challenge from a [...]
