Design of a deployable underwater robot for the recovery of autonomous underwater vehicles based on origami technique

ICRA 2021poster

The recovery of autonomous underwater vehicles (AUVs) has been a challenging mission due to the limited localization accuracy and movement capability of the AUVs. To overcome these limitations, we propose a novel design of a deployable underwater robot (DUR) for the recovery mission. Utilizing the o…

A Multitask Active Learning Framework for Natural Language Understanding

COLING 2020main

Natural language understanding (NLU) aims at identifying user intent and extracting semantic slots. This requires sufficient annotating data to get considerable performance in real-world situations. Active learning (AL) has been well-studied to decrease the needed amount of the annotating data and s…
