Building embodied AI systems that can follow arbitrary language instructions in any 3D environment is a key challenge for creating general AI.

Kernel Support Vector Machine Classifiers with the $\ell_0$-Norm Hinge Loss

no code implementations24 Jun 2023 Rongrong Lin, Yingjia Yao, YuLan Liu

In consideration of the nonconvexity and nonsmoothness of $\ell_0$-norm hinge loss, we first characterize the limiting subdifferential of the $\ell_0$-norm hinge loss and then derive the equivalent relationship among the proximal stationary point, the Karush-Kuhn-Tucker point, and the local optimal solution of $\ell_0$-KSVM.

Multi-turn RNN-T for streaming recognition of multi-party speech

no code implementations19 Dec 2021 Ilya Sklyar, Anna Piunova, Xianrui Zheng, YuLan Liu

Second, we propose a novel multi-turn RNN-T (MT-RNN-T) model with an overlap-based target arrangement strategy that generalizes to an arbitrary number of speakers without changes in the model architecture.

SynthASR: Unlocking Synthetic Data for Speech Recognition

no code implementations14 Jun 2021 Amin Fazel, Wei Yang, YuLan Liu, Roberto Barra-Chicote, Yixiong Meng, Roland Maas, Jasha Droppo

Our observations show that SynthASR holds great promise in training the state-of-the-art large-scale E2E ASR models for new applications while reducing the costs and dependency on production data.

Using Synthetic Audio to Improve The Recognition of Out-Of-Vocabulary Words in End-To-End ASR Systems

no code implementations23 Nov 2020 Xianrui Zheng, YuLan Liu, Deniz Gunceler, Daniel Willett

Different regularisation techniques are explored and the best performance is achieved by fine-tuning the RNN-T on both original training data and extra synthetic data with elastic weight consolidation (EWC) applied on the encoder.

Streaming Multi-speaker ASR with RNN-T

no code implementations23 Nov 2020 Ilya Sklyar, Anna Piunova, YuLan Liu

Recent research shows end-to-end ASR systems can recognize overlapped speech from multiple speakers.

Equivalent Lipschitz surrogates for zero-norm and rank optimization problems

no code implementations30 Apr 2018 Yulan Liu, Shujun Bi, Shaohua Pan

Specifically, we reformulate these combinatorial problems as equivalent MPECs by the variational characterization of the zero-norm and rank function, show that their penalized problems, yielded by moving the equilibrium constraint into the objective, are the global exact penalization, and obtain the equivalent Lipschitz surrogates by eliminating the dual variable in the global exact penalty.
