HGS-Mapping: Online Dense Mapping Using Hybrid Gaussian Representation in Urban Scenes

no code implementations29 Mar 2024 Ke wu, Kaizhao Zhang, Zhiwei Zhang, Shanshuai Yuan, Muer Tie, Julong Wei, Zijun Xu, Jieru Zhao, Zhongxue Gan, Wenchao Ding

However, integrating 3DGS into a street-view dense mapping framework still faces two challenges, including incomplete reconstruction due to the absence of geometric information beyond the LiDAR coverage area and extensive computation for reconstruction in large urban scenes.

A Theory of Multiple-Source Adaptation with Limited Target Labeled Data

no code implementations19 Jul 2020 Yishay Mansour, Mehryar Mohri, Jae Ro, Ananda Theertha Suresh, Ke wu

We present a theoretical and algorithmic study of the multiple-source domain adaptation problem in the common scenario where the learner has access only to a limited amount of labeled target data, but where the learner has at disposal a large amount of labeled data from multiple source domains.

Minimally Supervised Written-to-Spoken Text Normalization

no code implementations21 Sep 2016 Ke Wu, Kyle Gorman, Richard Sproat

In speech-applications such as text-to-speech (TTS) or automatic speech recognition (ASR), \emph{text normalization} refers to the task of converting from a \emph{written} representation into a representation of how the text is to be \emph{spoken}.
