JEP-KD: Joint-Embedding Predictive Architecture Based Knowledge Distillation for Visual Speech Recognition

no code implementations4 Mar 2024 Chang Sun, Hong Yang, Bo Qin

Visual Speech Recognition (VSR) tasks are generally recognized to have a lower theoretical performance ceiling than Automatic Speech Recognition (ASR), owing to the inherent limitations of conveying semantic information visually.

KDSM: An uplift modeling framework based on knowledge distillation and sample matching

no code implementations6 Mar 2023 Chang Sun, Qianying Li, Guanxiang Wang, Sihao Xu, Yitong Liu

The teacher model is the uplift decision tree (UpliftDT), whose structure is exploited to construct counterfactual sample pairs, and the pairwise incremental prediction is treated as another objective for the student model.

Physical Logic Enhanced Network for Small-Sample Bi-Layer Metallic Tubes Bending Springback Prediction

no code implementations20 Sep 2022 Chang Sun, Zili Wang, Shuyou Zhang, Le Wang, Jianrong Tan

In the second stage, under the physical logic, the PE-NET is assembled by ES-NET and SP-NET and then fine-tuned with the small sample BMT dataset and composite loss function.

Digital-twin-enhanced metal tube bending forming real-time prediction method based on Multi-source-input MTL

1 code implementation3 Jul 2022 Chang Sun, Zili Wang, Shuyou Zhang, Taotao Zhou, Jie Li, Jianrong Tan

To address this issue, a digital-twin-enhanced (DT-enhanced) metal tube bending forming real-time prediction method based on multi-source-input multi-task learning (MTL) is proposed.

Improving Correlation Capture in Generating Imbalanced Data using Differentially Private Conditional GANs

no code implementations28 Jun 2022 Chang Sun, Johan van Soest, Michel Dumontier

Finally, we present the balance between data utility and privacy in synthetic data generation considering the different data structure and characteristics of real-world datasets such as imbalance variables, abnormal distributions, and sparsity of data.

A Lightweight Dual-Domain Attention Framework for Sparse-View CT Reconstruction

no code implementations19 Feb 2022 Chang Sun, Ken Deng, Yitong Liu, Hongwen Yang

After the restored Radon data is reconstructed to an image, the image is sent into the second CAGAN trained for recovering the details, so that a high-quality image is obtained.

A Lightweight Structure Aimed to Utilize Spatial Correlation for Sparse-View CT Reconstruction

no code implementations19 Jan 2021 Yitong Liu, Ken Deng, Chang Sun, Hongwen Yang

Sparse-view computed tomography (CT) is known as a widely used approach to reduce radiation dose while accelerating imaging through lowered projection views and correlated calculations.
