An Audio-textual Diffusion Model For Converting Speech Signals Into Ultrasound Tongue Imaging Data

no code implementations9 Mar 2024 Yudong Yang, Rongfeng Su, Xiaokang Liu, Nan Yan, Lan Wang

In this model, the inherent acoustic characteristics of individuals related to the tongue motion details are encoded by using wav2vec 2. 0, while the ASR transcriptions related to the universality of tongue motions are encoded by using BERT.

Effective Open Intent Classification with K-center Contrastive Learning and Adjustable Decision Boundary

1 code implementation20 Apr 2023 Xiaokang Liu, Jianquan Li, Jingjing Mu, Min Yang, Ruifeng Xu, Benyou Wang

In this paper, we introduce novel K-center contrastive learning and adjustable decision boundary learning (CLAB) to improve the effectiveness of open intent classification.

Schema Inference for Interpretable Image Classification

1 code implementation12 Mar 2023 Haofei Zhang, Mengqi Xue, Xiaokang Liu, KaiXuan Chen, Jie Song, Mingli Song

In this paper, we study a novel inference paradigm, termed as schema inference, that learns to deductively infer the explainable predictions by rebuilding the prior deep neural network (DNN) forwarding scheme, guided by the prevalent philosophical cognitive concept of schema.

Multivariate Functional Regression via Nested Reduced-Rank Regularization

no code implementations10 Mar 2020 Xiaokang Liu, Shujie Ma, Kun Chen

We propose a nested reduced-rank regression (NRRR) approach in fitting regression model with multivariate functional responses and predictors, to achieve tailored dimension reduction and facilitate interpretation/visualization of the resulting functional model.

CommanderSong: A Systematic Approach for Practical Adversarial Voice Recognition

no code implementations24 Jan 2018 Xuejing Yuan, Yuxuan Chen, Yue Zhao, Yunhui Long, Xiaokang Liu, Kai Chen, Shengzhi Zhang, Heqing Huang, Xiao-Feng Wang, Carl A. Gunter

For this purpose, we developed novel techniques that address a key technical challenge: integrating the commands into a song in a way that can be effectively recognized by ASR through the air, in the presence of background noise, while not being detected by a human listener.
