ContentVec: An Improved Self-Supervised Speech Representation by Disentangling Speakers

1 code implementation20 Apr 2022 Kaizhi Qian, Yang Zhang, Heting Gao, Junrui Ni, Cheng-I Lai, David Cox, Mark Hasegawa-Johnson, Shiyu Chang

Self-supervised learning in speech involves training a speech representation network on a large-scale unannotated speech corpus, and then applying the learned representations to downstream tasks.

Unsupervised Text-to-Speech Synthesis by Unsupervised Automatic Speech Recognition

1 code implementation29 Mar 2022 Junrui Ni, Liming Wang, Heting Gao, Kaizhi Qian, Yang Zhang, Shiyu Chang, Mark Hasegawa-Johnson

An unsupervised text-to-speech synthesis (TTS) system learns to generate speech waveforms corresponding to any written sentence in a language by observing: 1) a collection of untranscribed speech waveforms in that language; 2) a collection of texts written in that language without access to any transcribed speech.

Cooperative Reasoning on Knowledge Graph and Corpus: A Multi-agentReinforcement Learning Approach

no code implementations4 Dec 2019 Yunan Zhang, Xiang Cheng, Heting Gao, ChengXiang Zhai

We model the question answering on KG as a cooperative task between two agents, a knowledge graph reasoning agent and an information extraction agent.

Macross: Urban Dynamics Modeling based on Metapath Guided Cross-Modal Embedding

no code implementations28 Nov 2019 Yunan Zhang, Heting Gao, Tarek Abdelzaher

As the ongoing rapid urbanization takes place with an ever-increasing speed, fully modeling urban dynamics becomes more and more challenging, but also a necessity for socioeconomic development.

Mining Hidden Populations through Attributed Search

no code implementations11 May 2019 Suhansanu Kumar, Heting Gao, Changyu Wang, Hari Sundaram, Kevin Chen-Chuan Chang

When the property of the target entities is not directly queryable via the API, we refer to the property as `hidden' and the population as a hidden population.
