WAE_RN: Integrating Wasserstein Autoencoder and Relational Network for Text Sequence

no code implementations CCL 2020 Xinxin Zhang, Xiaoming Liu, Guan Yang, Fangfang Li

In spite of the success of pre-trained language model in many NLP tasks, the learned text representation only contains the correlation among the words in the sentence itself and ignores the implicit relationship between arbitrary tokens in the sequence.

RedCore: Relative Advantage Aware Cross-modal Representation Learning for Missing Modalities with Imbalanced Missing Rates

no code implementations16 Dec 2023 Jun Sun, Xinxin Zhang, Shoukang Han, Yu-Ping Ruan, Taihao Li

Multimodal learning is susceptible to modality missing, which poses a major obstacle for its practical applications and, thus, invigorates increasing research interest.

A Reinforcement Learning Framework for Online Speaker Diarization

no code implementations21 Feb 2023 Baihan Lin, Xinxin Zhang

Our approach considers speaker diarization as a fully online learning problem of the speaker recognition task, where the agent receives no pretraining from any training set before deployment, and learns to detect speaker identity on the fly through reward feedbacks.

RTN: Reinforced Transformer Network for Coronary CT Angiography Vessel-level Image Quality Assessment

no code implementations13 Jul 2022 Yiting Lu, Jun Fu, Xin Li, Wei Zhou, Sen Liu, Xinxin Zhang, Congfu Jia, Ying Liu, Zhibo Chen

Therefore, we propose a Progressive Reinforcement learning based Instance Discarding module (termed as PRID) to progressively remove quality-irrelevant/negative instances for CCTA VIQA.

Steady-state nonlinearity of open-loop reset systems

no code implementations21 Jun 2022 Marcin B. Kaczmarek, Xinxin Zhang, S. Hassan HosseinNia

In this paper, we introduce a new representation for open-loop reset systems.

Frequency-domain analysis for reset systems using pulse-based model

no code implementations1 Jun 2022 Xinxin Zhang, Marcin B Kaczmarek, S. Hassan HosseinNia

In this paper, a new analytical technique for reset controllers is proposed to break the limitations.

Geodesic Paths for Image Segmentation with Implicit Region-based Homogeneity Enhancement

no code implementations16 Aug 2020 Da Chen, Jian Zhu, Xinxin Zhang, Ming-Lei Shu, Laurent D. Cohen

Minimal paths are regarded as a powerful and efficient tool for boundary detection and image segmentation due to its global optimality and the well-established numerical solutions such as fast marching method.

Speaker Diarization as a Fully Online Learning Problem in MiniVox

1 code implementation8 Jun 2020 Baihan Lin, Xinxin Zhang

We proposed a novel machine learning framework to conduct real-time multi-speaker diarization and recognition without prior registration and pretraining in a fully online learning setting.

Hierarchical Optimization Time Integration for CFL-rate MPM Stepping

1 code implementation18 Nov 2019 Xinlei Wang, Minchen Li, Yu Fang, Xinxin Zhang, Ming Gao, Min Tang, Danny M. Kaufman, Chenfanfu Jiang

We propose Hierarchical Optimization Time Integration (HOT) for efficient implicit time-stepping of the Material Point Method (MPM) irrespective of simulated materials and conditions.
