Single-Codec: Single-Codebook Speech Codec towards High-Performance Speech Generation

no code implementations11 Jun 2024 Hanzhao Li, Liumeng Xue, Haohan Guo, Xinfa Zhu, YuanJun Lv, Lei Xie, Yunlin Chen, Hao Yin, Zhifei Li

The multi-codebook speech codec enables the application of large language models (LLM) in TTS but bottlenecks efficiency and robustness due to multi-sequence prediction.

Disentangling Heterogeneous Knowledge Concept Embedding for Cognitive Diagnosis on Untested Knowledge

Distributed Extended Object Tracking Using Coupled Velocity Model from WLS Perspective

no code implementations24 Aug 2023 Zhifei Li, Yan Liang, Linfeng Xu

Under the consensus scheme, a distributed WLS filter over a realistic network with ``naive'' node is developed by proper weighting of the priors and measurements.

Object Tracking

Distributed Extended Object Tracking Information Filter Over Sensor Networks

no code implementations3 Nov 2021 Zhifei Li, Yan Liang, Linfeng Xu, Shuli Ma

This work aims to design a distributed extended object tracking (EOT) system over a realistic network, where both the extent and kinematics are required to retain consensus within the entire network.

Are You for Real? Detecting Identity Fraud via Dialogue Interactions

1 code implementation IJCNLP 2019 Weikang Wang, Jiajun Zhang, Qian Li, Cheng-qing Zong, Zhifei Li

In this paper, we focus on identity fraud detection in loan applications and propose to solve this problem with a novel interactive dialogue system which consists of two modules.

A Teacher-Student Framework for Maintainable Dialog Manager

no code implementations EMNLP 2018 Weikang Wang, Jiajun Zhang, Han Zhang, Mei-Yuh Hwang, Cheng-qing Zong, Zhifei Li

Specifically, the {``}student{''} is an extended dialog manager based on a new ontology, and the {``}teacher{''} is existing resources used for guiding the learning process of the {``}student{''}.
