Dynamem: Online Dynamic Spatio-Semantic Memory for Open World Mobile Manipulation

ICRA 2025

Significant progress has been made in openvocabulary mobile manipulation, where the goal is for a robot to perform tasks in any environment given a natural language description. However, most current systems assume a static environment, which limits the system's applicability in realworld scenarios

GraphEQA: Using 3D Semantic Scene Graphs for Real-time Embodied Question Answering

CoRL 2025poster

In Embodied Question Answering (EQA), agents must explore and develop a semantic understanding of an unseen environment in order to answer a situated question with confidence. This remains a challenging problem in robotics, due to the difficulties in obtaining useful semantic representations, updati…

LiSenNet: Lightweight Sub-band and Dual-Path Modeling for Real-Time Speech Enhancement

ICASSP 2025accepted

Speech enhancement (SE) aims to extract the clean waveform from noise-contaminated measurements to improve the speech quality and intelligibility. Although learning-based methods can perform much better than traditional counterparts, the large computational complexity and model size heavily limit th…

Learning to Detect Noisy Labels Using Model-Based Features

EMNLP 2022finding

Label noise is ubiquitous in various machine learning scenarios such as self-labeling with model predictions and erroneous data annotation. Many existing approaches are based on heuristics such as sample losses, which might not be flexible enough to achieve optimal solutions. Meta learning based met…
