Dynamic Graph Node Classification via Time Augmentation
Jiarui Sun, Mengting Gu, Chin-Chia Michael Yeh +3
Node classification for graph-structured data aims to classify nodes whose labels are unknown. While studies on static graphs are prevalent, few studies have focused on dynamic gra…
Last-Mile Embodied Visual Navigation
Justin Wasserman, Karmesh Yadav, Girish Chowdhary +2
Realistic long-horizon tasks like image-goal navigation involve exploratory and exploitative phases. Assigned with an image of the goal, an embodied agent must explore to discover…
Proactive Anomaly Detection for Robot Navigation with Multi-Sensor Fusion
Tianchen Ji, Arun Narenthiran Sivakumar, Girish Chowdhary +1
Despite the rapid advancement of navigation algorithms, mobile robots often produce anomalous behaviors that can lead to navigation failures. The ability to detect such anomalous b…
Visual Servoing for Pose Control of Soft Continuum Arm in a Structured Environment
Shivani Kamtikar, Samhita Marri, Benjamin Walt +3
For soft continuum arms, visual servoing is a popular control strategy that relies on visual feedback to close the control loop. However, robust visual servoing is challenging as i…
Disentangling Successor Features for Coordination in Multi-agent Reinforcement Learning
Seung Hyun Kim, Neale Van Stralen, Girish Chowdhary +1
Multi-agent reinforcement learning (MARL) is a promising framework for solving complex tasks with many agents. However, a key challenge in MARL is defining private utility function…
Distributed State Estimation with Deep Neural Networks for Uncertain Nonlinear Systems under Event-Triggered Communication
Federico M. Zegers, Runhan Sun, Girish Chowdhary +1
Distributed state estimation is examined for a sensor network tasked with reconstructing a system's state through the use of a distributed and event-triggered observer. Each agent…
